Fukushima on Young Members’ agenda

By Elia Merzari

The American Nuclear Society’s Young Members Group, with the help of ANS’s Nuclear Installation Safety Division, is organizing a panel session at the Young Professionals Congress (an embedded topical at the 2011 ANS Winter Meeting) on the history of severe nuclear accidents.

A primary focus for the YMG is the transfer of knowledge, and this session will provide unique perspectives from individuals involved in the world’s most prominent nuclear events. The lessons learned from these front-line individuals will be invaluable for the new generation of workers in the nuclear power industry.

Before the events at Fukushima in Japan, the most recent severe accident took place more than 25 years ago at Chernobyl, making it reasonable for  younger people to have a slim perspective on the impacts of severe events. In addition, young members may have a limited knowledge of past accidents and certainly won’t have direct personal experience. The panel session at the winter meeting will focus on the lessons learned from Chernobyl and Three Mile Island, and how these events have profoundly shaped our understanding of severe accidents. In particular, this session will also address how these lessons have been applied to the response to Fukushima.

With the help of Alan Levin, of Areva, we are able to bring together notable panelists who will tackle the issues from different perspectives:

  • Michael Corradini (University of Wisconsin, ANS Special Committee on Fukushima and ANS vice president/president-elect) will give a brief summary on the conclusions drawn by the ANS special committee.
  • Masanori Naitoh (Institute of Applied Energy, Japan) will discuss in detail the event sequence at Fukushima, and address the very important question, “Why did such a catastrophe occur, even after the lessons learned from TMI and Chernobyl?”
  • Dana Powers (Sandia National Laboratory) and Joy Rempe (Idaho National Laboratory) will discuss what was learned from TMI and Chernobyl. Powers also will discuss the history of the source term in the TMI accident, while Rempe will address insights from TMI’s accident progression. Rempe’s presentation will include videos related to the events immediately following the accident and the relocated debris and damaged internal structures within the TMI-2 vessel.
  • Brian Sheron (Nuclear Regulatory Commission) will discuss the regulator perspective on severe accidents with a focus on recent events.

We hope that you will attend this session at the 2011 Young Professionals Congress, scheduled in the morning on Tuesday, November 1st, 2011, at the Omni Shoreham hotel in Washington DC.

ANS urges NRC to take action on Yucca Mountain

ANS President Eric Loewen sends letter to Chairman Jaczko and NRC commissioners to stress the importance and obligation to complete licensing application

Eric Loewen, president, American Nuclear Society

The American Nuclear Society has delivered an August 22 letter to Nuclear Regulatory Commission chairman Gregory Jaczko and the NRC commissioners to urge the agency to complete the consideration of the licensing application for the Yucca Mountain used fuel repository, ANS President Eric P. Loewen announced.

“As a professional and scientific society, ANS has chosen not to take a position on the suitability of Yucca Mountain as a repository site,” he said. “However, we have become increasingly concerned that NRC has not defined a clear pathway to complete the licensing process. Failure of the NRC to judge the Yucca application on its merits would be a triumph of shortsighted politics over science. That’s why ANS has come off the sidelines.”

The letter noted that the NRC’s Atomic Safety and Licensing Board has determined that the motion to “withdraw” the license application by the Department of Energy does not relieve the commission of its duty to review the application and make a determination on its technical merits.

Loewen added that the United States Court of Appeals, as recently as July 1, 2011, ruled that the NRC is required by the Nuclear Waste Policy Act to review the application. Nevertheless, the letter continues, “the NRC, without an open formal decision of its own, has suspended . . . review of the application and . . . refused to release . . . the Safety Evaluation Report.”

Loewen stated, “Our members are concerned that if the commission does not act, the court will order it to do so, thereby inflicting indelible harm to the commission’s reputation for scientific professionalism and independence. We urge the commission to protect its traditions of openness, objectivity, and excellence by completing the scientific review of this matter.”

The Las Vegas Review Journal has coverage of the ruling by the U.S. Court of Appeals on July 1, 2011.

Click here for the text of the letter from Loewen to the NRC.

Newsweek interviews Loewen

Loewen was interviewed by the online edition of Newsweek magazine  (The Daily Beast) this week about the letter. In the interview, Loewen pointed out that the DOE had studied Yucca since the late 1970s before handing it off to the NRC in 2008. When the funding from Washington ended, the NRC ended its review of the site.

ANS officers, many of them former industry leaders and academics, argue that the licensing process should be finished regardless of the project’s prospect of actually operating.

“We try to stay out of the politics and argue from a technical standpoint, but we’re just so frustrated as a technical community we want to come off the sidelines,” said Loewen.

Yet, the decision to shutter Yucca has long been considered political in nature. President Obama ordered the action under pressure from Senate Majority Leader Harry Reid (D., Nev.).

All five commissioners, including Jaczko, declined to discuss the ANS letter and the NRC’s stalled progress on Yucca with the Daily Beast. But some have taken public stances against Jaczko’s decision to halt the project. William Ostendorff, who sits on the commission until 2016, told Congress last fall that he agreed that the NRC still had an obligation to investigate Yucca and other potential repository sites.

Hurricane Irene Watch ~ Sunday Aug 28; 0830

Follow the ANS Twitter feed for breaking news@ans_org

Update 08/29/11: The NRC Event Report for August 29, 2011, indicates the hurricane had more impact on nuclear reactors over the weekend than reported in the news media.   None of these events involved the release of radiation and there are no injuries associated with them.  See the report itself for details.

One unit shut at CENG

Constellation Energy Nuclear Group (CNEG) reported Unit 1 at its Calvert Cliff, Maryland refinery was shut automatically after a transformer in the switchyard was hit by a piece of aluminum siding from a nearby building.

CENG said the facility is safe, with no impact on employees at the plant or threat to the surrounding area.

The company declared an ‘Unusual Event’ – the lowest of four emergency classifications by the Nuclear Regulatory Commission.

“The Unit 1 reactor at CENG’s Calvert Cliffs, Maryland facility automatically went off-line,” a CENG spokesman said.

“It appears as if due to heavy gusts of winds caused by Hurricane Irene, a large piece of aluminum siding dislodged from a building. The siding came in contact with our main transformer. The facility is safe.”

Oyster Creek shuts down safely

Exelon Corp took its Oyster Creek nuclear power plant in New Jersey offline at 5 pm EDT Saturday. The plant initially lowered power to 30% as part of an orderly and safe shutdown process in anticipation of high winds from the hurricane. The plant must close when winds exceed 75 mph.

Update 1300 hrs; 08/28/11: Oyster Creek reports a walk down of the plant reports no damage to the facilities.

In New Jersey Gov Christie urged sightseers to get off the beach and out of harms way.

Millstone reduces power

Dominion Resources Inc is reducing power at its two-unit Millstone plant in Connecticut, a company spokesman said.

Brunswick reduces power

Progress Energy’s Brunswick nuclear plant, located on the North Carolina coast, cut to 65 to 75 percent power late Friday and does not expect to return to full power until after the storm has fully passed, a spokesman said.

Indian Point Ready

Entergy company officials say their Indian Point nuclear power plant in Buchanan is “designed and built to withstand extreme weather.” Staff has worked “diligently this past week to ensure our plants are prepared for any impacts resulting from this storm,” according to Entergy Nuclear President John Herron.

He said the company is coordinating emergency communications systems with the NRC, FEMA and state agencies and backup diesel-powered generators are available to provide electricity to plant safety systems if power is lost. If offsite power goes down, Indian Point is designed to safely shut down if its needs to, Herron said.

He said under severe weather procedures, plant operators monitoring area wind speeds may actually take precautionary actions to begin shutting the plants down prior to those winds reaching the site.

Update 1300 hrs; 08/28/11: Entergy reports  Indian point and Vermont Yankee are operating normally with no storm damage.

NRC monitoring plant status

The U.S. Nuclear Regulatory Commission said it sent additional staff to monitor conditions and storm preparation at the 14 nuclear units from Maryland to New Hampshire in Irene’s path as well as a nuclear fuel production plant in North Carolina.

Up and down the east coast nearly three million people are without power and more outages are expected as the hurricane heads north northeast at 25 mph into New England states.  At 0830 the center of the hurricane was over central Connecticut.

There are no media reports this morning of any reactor shutdowns, but that may be a function of the wire services. The NRC website does not provide real time information on reactor status.  The Washington Post published this table of the expected progress of the storm over the next several days.

Timing of Impacts from Hurricane - Table source: Washington Post 08/27/11

The Weather Channel is reporting that the hurricane made landfall near Cape Lookout, NC, this morning with 85 mph winds. The NRC requires reactors to shut down when wind speeds exceed 74 mph. Expect closures later today and Sunday assuming wind speeds do not decrease over time.  See AP list of reactors below.

A live stream of the Weather Channel’s coverage of the hurricane’s progress up the east coast is found here.

Weather Channel

Nuclear reactors sit on eight coastal sites along the Eastern seaboard in the projected path of Hurricane Irene. They are built to withstand winds much stronger than those expected from Irene. They are also equipped with backup generators protected from flooding to provide power to keep the reactor cool if outside power is lost. Still, some will likely be shut down as a precaution in advance of Irene’s winds and heavy rains.

Hurricane Irene Watch ~ Friday Aug 26; 1700

Projected path of Hurricane Irene 8/26-28/2011

1700 HRS Aug. 26, 2011—Nuclear energy facilities are prepared to safely withstand high winds and heavy rain as the eastern United States braces for Hurricane Irene to make landfall this weekend.

When hurricanes occur, electric utilities operating nuclear energy facilities take specific actions mandated by U.S. Nuclear Regulatory Commission guidelines and the plants’ emergency preparedness plan. These include:

  • Plant personnel monitor storm conditions, paying close attention to the path of a storm and wind speeds at the site.
  • Personnel inspect the entire facility and secure or move any equipment that could possibly become airborne due to high winds.
  • Each plant site has numerous emergency backup diesel generators that are tested and ready to provide electricity for critical operations in the event of a loss of off-site electricity supply. Diesel fuel tanks are checked and topped off to ensure there is a minimum of seven days of fuel to power backup generators.
  • As a precaution, a reactor will be shut down at least two hours before the onset of hurricane-force winds at the site, typically between 70 and 75 miles per hour.
  • Twelve hours before Hurricane Irene approaches nuclear energy facilities on the East Coast, plant operates at each site will provide status updates to the Nuclear Regulatory Commission.

If there is a loss of off-site power, reactors automatically shut down as a precaution and the emergency backup diesel generators begin operating to provide electrical power to plant safety systems. Plant operators also may manually shut down the reactor as a precaution even if off-site power is still available.

Nuclear power plants are the most robust facilities in the U.S. infrastructure, with reactor containment structures composed of steel-reinforced concrete that have proven their ability to withstand extreme natural events.

In addition, nuclear plant operators are trained and tested one out of every six weeks to safely manage extreme events such as hurricanes. Plant operators also have multi-day staffing plans, and resources, to ensure that personnel are on-site and prepared to respond to situations that may arise as a result of the storm.

NRC notes reactor preparation

The NRC’s Roger Hannah told wire services Aug 26 that typically utilities begin shutting down reactors 12 hours before winds reach speeds of 74 miles an hour.  He pointed out there is a big difference between a storm surge and a tsunami.

In Washington, DC, the NRC is mobilizing its emergency operations center to keep track of conditions at all the nuclear reactors up and down the U.S. eastern seaboard.  The center stays in close touch with resident inspectors at the plants. If land lines go out, they switch to satellite phones to stay in touch.  Once the storm has pass, the NRC works with FEMA to assess any damage.

Social Media

Roundup of site specific news

While preparations are generally the same at all reactors when faced with an imminent hurricane, here are some highlights from the different sites.

* At Dominion’s Millstone nuclear plant in Connecticut, which is located on Long Island sound near Waterford, CT, workers are preparing defenses against an expected storm surge.  Staffing plans for storm emergencies are being put into effect.  Outside maintenance project are being postponed until after the storm passes.

* At Energy’s Indian Point, protection of the two reactors there focuses on possible wind damage to the switch yard. If off-site power is lost, the plant will run on emergency diesel generators.

* Similar preparations are underway at Constellation’s two reactors at Calvert Cliffs, MD, and, at PSEG’s Salem and Hope Creek reactors which face the Delaware River estuary in southwestern NJ.

At Constellation plant manager said that staff working in the Emergency Response Organization (ERO) will be tasked to 12 hour duty shifts and all ERO personnel will remain on site.  Staff use a checklist to insure they bring necessary items with them for the shifts.  Sleeping areas and round the clock cafeteria access are mobilized for the duration.

* At Exelon’s Oyster Creek reactor, which faces the Atlantic ocean in southeastern NJ, workers are securing equipment that might be impacted by high winds.  Emergency diesel generators are checked to insure they are ready to run and have reserves of fuel.

* In North Carolina Progress Energy began preparations on Wednesday of this week at its Harris and Brunswick plants.    Brunswick is designed to withstand a storm surge of 22 feet above sea level.  The plant will continue to operate unless winds rise above 75 mph.

Plants are built to withstand high winds

Nuclear energy facilities are designed to withstand natural occurrences greater than those encountered in the regions where they are located. They are built to withstand floods, earthquakes and high winds, and have numerous safety systems that will operate and safely shut the reactor down in the event of a loss of off-site power. These plant designs are routinely reviewed and modifications are made to assure their integrity and safety.

North Anna restores off-site power

Dominion’s North Anna Power Station Restores Offsite Power

RICHMOND, Va., Aug. 23, 2011 /PRNewswire/ — Dominion Virginia Power’s North Anna Power Station has restored off-site power, eliminating the need to rely on its back-up generators. The station remains in an Alert, the second lowest of the four emergency classifications of the U.S. Nuclear Regulatory Commission.

The station’s two nuclear reactors shut down following an earthquake near the station that occurred at 1:51 p.m. EDT today. The reactors shut down automatically and no damage has been reported to systems required to maintain the station in a safe condition. Several aftershocks felt in the region that occurred later today did not affect the station.

As designed, four diesel generators supplied power to the station while the off-site power was unavailable. One of the four generators was taken off-line to repair a generator coolant leak, but a fifth generator at the station was activated to replace it until the offsite power was restored. Repairs are complete to the diesel generator.

The company also inspected the Lake Anna Dam after the earthquake and determined it sustained no damage. Station inspections are continuing to assure no damage has resulted from the seismic event.

No release of radioactive material has occurred beyond those minor releases associated with normal station operations.

The earthquake was felt at the company’s other nuclear power station, Surry Power Station in southeast Virginia, but not as strongly. Both units at Surry continue to operate safely. Surry has exited a Notification of Unusual Event (NOUE) it declared earlier today, the least serious of four NRC emergency classifications.

U.S. nuclear power stations, including Dominion’s four stations, were built to seismic standards for their regions.

Safe shutdown achieved at Dominion’s North Anna site following 5.8 magnitude earthquake

A 5.8 magnitude earthquake (USGS data) shook much of the east coast at 1:51 PM eastern time today. Dominion’s North Anna reactors went off line safely and are on emergency power using four diesel generators.  (See full text of NRC press release below)

The epicenter was reported the U.S. Geological Survey to be near Mineral, VA, (map) about 15 miles from the plant at a depth of about four miles below the surface.  An aftershock was reported in the area at a magnitude of 2.8 on the Richter scale  soon after.

Dominion reported its reactors shut down safely as a result of a loss of off-site power.  The utility declared an “unusual event” to the NRC.  The Wall Street Journal reported that the power loss was caused by problems in the reactor’s switch yard.

“Jim Norvelle, director of media relations for Dominion Resources Inc., operator of the North Anna plant, said its workers inspected the switch yard, through which electricity enters and leaves the installation, and believe problems there caused the nuclear plant to lose access to grid power. When the plant lost access to grid power, it automatically shut down.”

“We did lose on-site power, but all the diesel generators are up and running,” Dominion spokesman Richard Zuercher said 30 minutes after the quake. “Everything appears to be operating just fine.”  Dominion is providing real time updates via its Twitter feed. @DomVAPower  The first official press release from Dominion repeats this information.

NBC Nightly News reported at 18:45 HRs that one of the four emergency diesel generators did not start.  Bloomberg Wire service reported one of the four diesel generators stopped working after startup, David McIntyre, a spokesman for the U.S. Nuclear Regulatory Commission, said in an e-mail.

Zuercher said North Anna’s operators were preparing to manually shut down the units after the quake when the power station’s operating system automatically powered down both units.

Zuercher told local reporters that diesel generators started as expected to maintain cooling. Dominion’s two-unit Surry nuclear power plant, also in the region, was not affected and continues to operate. Reuters reports that Dominion’s two reactors at its Surry plant in Gravel, VA, continue to operate normally.

Twelve other reactors in the northeast that measured earthquake effects also reported them to the NRC, but none of them shut down. None of them reactors reported any damage from the earthquake.

Nuclear Regulatory Commission spokesman Roger Hannah told wire services the agency was not immediately aware of any damage at nuclear power plants in the southeast.  The NRC reported that all other nuclear reactors in the northeast continued to operate normally.

The North Anna site is composed of two Westinghouse PWR units that generate approximately 1,800 MW of power.

Unit 1 began commercial operation in June, 1978 and Unit 2 followed in December 1980.

NRC MONITORING ALERT AT NORTH ANNA
FOLLOWING VIRGINIA EARTHQUAKE
No. 11-153
August 23, 2011

The U.S. Nuclear Regulatory Commission headquarters in Rockville, Md., is monitoring an Alert at the North Anna nuclear power plant in Virginia, following today’s earthquake in central Virginia. The NRC is also monitoring Unusual Events, the lowest emergency classification, declared at several other Eastern U.S. nuclear power plants. In accordance with agency procedures, the NRC’s regional offices in King of Prussia, Pa., and Atlanta have activated their incident response centers. NRC resident inspectors at the affected nuclear power plants will continue to monitor conditions for the duration of the event.

North Anna declared its Alert, the second-lowest of the NRC’s four emergency classifications, when the plant lost electricity from the grid following the quake just before 2 p.m. Tuesday. Power is being provided by onsite diesel generators and the plant’s safety systems are operating normally. Plant personnel and NRC resident inspectors are continuing to examine plant conditions.

NRC staff in the Maryland headquarters felt the quake and immediately began checking with U.S. nuclear power plants. The NRC is in direct communications with North Anna and is coordinating its response with other federal agencies.

Nuclear power plants are built to withstand environmental hazards, including earthquakes. Even those plants that are located outside of areas with extensive seismic activity are designed for safety in the event of such a natural disaster. The NRC requires that safety-significant structures, systems, and components be designed to take into account the most severe natural phenomena historically reported for the site and surrounding area.

Plants declaring Unusual Events, which indicate a potential decrease in plant safety, include Peach Bottom, Three Mile Island, Susquehanna and Limerick in Pennsylvania; Salem, Hope Creek and Oyster Creek in New Jersey, Calvert Cliffs in Maryland, Surry in Virginia, Shearon Harris in North Carolina and D.C. Cook and Palisades in Michigan. All these plants continue to operate while plant personnel examine their sites.

Profiles of Exceptional Women in Nuclear Energy

Editor: Dan Yurman

Nuclear energy, like many other highly technical science and engineering fields, was led in the post World War II era by men. In the decades that followed, many women entered the field. An indication of how much that presence has grown is that the Women in Nuclear (WIN) organization now lists 4,500 members, according to a press release from the Nuclear Energy Institute, which is a sponsoring organization for WIN.

The latest crowd sourced blog post here at ANS Nuclear Cafe is a series of profiles of exceptional women in the nuclear energy field. ANS asked for brief profiles for publication and we are very pleased to present them here.

These are  first person stories, e.g., “How I become a nuclear professional and the importance of what I have achieved” in terms of career satisfaction, work-life balance, career ladders, technical mastery, or meeting a management challenge.

We published these profiles  because we think that they tell interesting stories, and we hope you agree.

I grew up following the space program and knew by the time that I got to high school that I wanted to study engineering in college. I wanted to be one of the people who knew how complicated things worked and who made complicated things work. The colleges that I was applying to required a choice of major. I literally looked down the list of engineering majors and passed judgment on each option. When I got to “nuclear” on the list, it sounded interesting and hard. I picked nuclear engineering, and have never looked back.

In college, I joined the cooperative education (co-op) program, which meant that I alternated work and school semesters to earn money and gain work experience. Co-op was also a wonderful opportunity to live away from home and school and to test myself in the real world.

In 1989, after 12 years at Savannah River Site, I joined Southern Nuclear as a core designer for the Vogtle 2 nuclear power plant. I worked in core design and fuel-related licensing until 2006, when I moved into nuclear fuel procurement. More recently my responsibilities have expanded to include characterization of burned fuel for dry cask storage, burned fuel inspection activities, and new fuel fabrication oversight—all in addition to fuel procurement.

I love seeing my ideas put into action. I love the idea that I help make electricity, which has such a profoundly positive impact on peoples’ lives.

My mother was an English teacher and my father was an engineer. They seldom agreed on politics or religion, but they always agreed on the importance of education and personal values. Growing up, family time was an opportunity to learn and practice open debate, with the most valuable lesson being that I learned to ask really good questions.

I’ve had exceptional opportunities to study and manage large, complex technological and natural systems to understand energy, environmental, and political intersections. These inextricably integrated systems require our continued stewardship and trade-off solutions by our best scientists, engineers, and social scientists.

As a parent, consumer, engineer, and global citizen, it’s important to me that we evaluate all energy options. As science and technology innovations lead us to review new trade-offs, we must continue to question and weigh options. Our social and economic stability depends on a flexible and diverse energy portfolio. Most of my career I’ve advised policy, business, and industry decision makers. And, it’s clear to me that nuclear energy is an essential component of a sustainable, emissions-free energy system.

I’m proud to be part of the Westinghouse tradition of excellence and innovation in science and technology. The AP1000® is the safest and most efficient nuclear reactor ever designed and licensed. In addition, I’m confident that our small modular reactor will offer an equally safe and efficient choice that customers can rely on in an increasingly carbon-regulated world.

I’ve never been one to plot my career path. Instead, I’ve gravitated toward work that makes a lasting contribution to the world that our children will inherit. We’ll never have all the answers, but we have an ethical responsibility to be fearless about asking all the questions.

I arrived at Westinghouse as a new college graduate two years ago. My first days provided an impressive perspective on the level of responsibility available for young engineers in the nuclear industry. With a growing number of engineers approaching retirement age and the rapid changes around new nuclear technology, there are numerous opportunities to learn and advance. My first months at Westinghouse were spent immersing myself in learning about loss-of-coolant accident (LOCA) long-term cooling analysis for the entire Westinghouse C-E reactor (Combustion Engineering) fleet of plants. The expectation was that, over time, I would amass enough knowledge to serve as the new subject matter expert.

I was initially overwhelmed by the high expectations of the nuclear industry. Getting up to speed with the volumes of knowledge was no small feat. Most knowledge transfer on older technology occurred in one-on-one information sharing sessions. I spent weeks meeting with previous experts, documenting everything they told me.

Now I feel light-years away from where I started. LOCA long-term cooling analysis is a current Nuclear Regulatory Commission focus. As a result, I’ve faced several difficult questions from the staff. I’ve learned to rely on my peers and other resources because an accurate answer is more important than an immediate answer. The biggest lesson learned, however, is to never try to do everything on your own!

This experience has been highly rewarding. I’ve recently presented in front of the NRC, traveled to several plants, and spoken with customers about my work. Although I’ve only worked in the industry for two years, I can now consider myself a subject matter expert!

I was going to major in music. I played clarinet in the Phoenix Youth Symphony and in my high school band. I loved it. But the music programs in high schools were being cut as state budgets were reduced. I’m practical, so I considered other options. I had grown up around engineers and scientists. My father was a chemical engineer and worked at the Lawrence Livermore National Laboratory for many years. I was good at math and science, and I enjoyed it. So I decided to look into engineering, which was a good combination of math, science, and practicality.

My high school physics teacher would often talk about nuclear energy. It sounded interesting, so I decided to major in nuclear engineering. I received my B.S. in nuclear engineering from the University of Arizona (where I had a wonderful mentor in Norman Hillberry, one of the designers of the first nuclear reactor, Chicago Pile), and my M.S. and Ph.D. in nuclear engineering from the University of California, Los Angeles. My area of research was fusion energy. Research in fission was limited then, and fusion energy had lots of interesting research options.

After graduate school, I worked for six months at the Kernforschungszentrum, Karlsruhe, research institution in Germany and then for a year in the Soviet Union, before coming to the Idaho National Laboratory, where I’ve worked for 20 years, first in fusion and then in fission technology.

My husband of 25 years is one of the main reasons that I’m successful. He’s an engineer with a Ph.D., and he has always been supportive of my career. We’ve raised two wonderful boys (my most important job), and I’ve been able to balance work and family most of the time.

My current role at INL is Deputy Associate Laboratory Director for Nuclear Science and Technology, where I’m responsible for the execution of about $250 million worth of research and development programs.

I miss playing clarinet, but began taking piano lessons several years ago, so I still have my foot in that door, too.

Whenever I talk to students about careers, I always tell them that careers are like snowflakes—no two are alike. Even if someone goes to the same university or takes the same first job, the landscape changes over time, and a second person can never follow the identical path.

Therefore, I tell them not to put too much emphasis on a career model. Instead, I emphasize the value of broad skills, diverse experiences, flexibility, and networking. And of how volunteering in one’s professional society can help career progression.

When I first joined ANS, I really didn’t have any expectation of getting involved in Society governance. But ANS ticked me off by issuing a pink badge, used for spouses, to my husband (really!), and then one thing led to another.

At some point, I realized that being involved in Society activities was benefiting me in many ways. Early in my career, it gave me opportunities to learn and exercise skills I later applied in my workplace. Throughout my career, it also gave me a chance to get to know many people outside my own field and my own organization.

If this sounds like an ad for ANS, so be it. The opportunities within ANS are numerous and diverse, so there is something for almost every interest. I encourage every member of ANS, but particularly the younger members, to get involved. Volunteering in ANS will not lead everyone to the same path I followed, but it will almost certainly prove a valuable experience.

As for me, I always wonder how my career would have evolved if ANS had not handed my husband a pink badge. In retrospect, I guess I’m grateful they did.

receiving an undergrad degree in journalism from the University of Texas, a graduate degree in communications management from Syracuse University, and
by working in the publishing world in Manhattan and Birmingham, Ala. But all
roads led her home, back to her roots in Vicksburg, Miss., where she married
an engineer who worked in nuclear at Entergy’s nearby Grand Gulf Nuclear
Station.

Beginning her Entergy career 25 years ago as a technical editor at Grand
Gulf, Barfield has successfully navigated the organization chart from
nuclear to utility positions back to nuclear, giving her a unique breadth
and competency in the nuclear sector. Leading national efforts and
considered a respected, knowledgeable thought-leader, Barfield’s passion for
the nuclear industry is noteworthy.

When Toni Beck was hired by Entergy as a new corporate communications group vice president at the New Orleans headquarters, she saw the opportunity to weave Entergy’s nuclear advocacy efforts into the broader public awareness that Entergy tries to instill about all aspects of energy policy.

Barfield is now shaping a new position created at Entergy: Vice President for Advocacy Communications. With bold thinking for the corporate giant, Beck is
leveraging Barfield’s management and industry expertise, moving her from the
nuclear headquarters in Jackson, Miss., to the New Orleans office
overlooking the Louisiana Superdome.

Barfield commented that the shape of the Superdome reminds her of a short,
fat cooling tower. “Once a nuke, always a nuke,” she remarked as she
packed boxes for her new office. This nuke isn’t going too far, only
up.

How does a kid (especially a girl) who attended high school in the same small Texas town that her mother grew up in end up with a PhD in nuclear engineering and an officer of an 11,000 member organization like the American Nuclear Society?

I often wonder myself, how did I get here? Most of my family (still in rural Texas) think I’m stubborn enough to do anything, but they wonder what DO I do?

In high school, I wrote a research paper on nuclear power. It was totally awe inspiring to think of the amount of energy that is released from something you couldn’t even see. After all the work (grades, testing, essay writing, etc.) associated with applying for colleges and scholarships (my only option for college), I decided I should be pursuing something that really excited me…so I checked a box that said “nuclear engineering.” I spent my first four years of college trying to figure out exactly what an engineer was!

By the time I finished my B.S., we were just getting to the good stuff. I stayed for my M.S., which included spending time at the university’s TRIGA reactor, and then for my PhD, which culminated in a three-year graduate research opportunity at Los Alamos National Laboratory. Wow, was I a long way from home!

I found a lot of support in my early involvement in ANS—both as a student and as a professional. That experience gave me confidence and provided opportunities for me to grow as a professional. ANS was also where I learned that nuclear is so much more than an academic study, a lab experiment, or electricity generation. It’s a powerful science with applications in medicine, space exploration, agriculture, food processing, etc. There are endless opportunities to support and improve current applications and to identify new uses of nuclear science and technology. For many developing countries, nuclear is the option that most effectively enables them to increase the standard of living for the masses.

After more than 25 years, I’m still jazzed by the potential of nuclear and thankful that I have the opportunity everyday to learn something new.

Mysteries and Thrillers in the Dog Days: Lessons for Nuclear Communication

By Meredith Angwin

It’s the Dog Days of Summer (at least by some definitions).

The Connecticut River Valley lies quiet and breezeless at midday. I eat buttery corn and heart-healthy tomatoes.  To everything there is a season, and this is the season when I take my nuclear-communications lessons from mysteries and thrillers.

Success, Not Victory: My First Lesson

John Buchan was a Times correspondent in France during World War I, and later the  Governor-General of Canada.

Buchan was a pretty busy man, but he also managed to write about a hundred books.  In 1915, he wrote The Thirty-Nine Steps, which later became a Hitchcock movie. The hero, Richard Hannay, is also the hero of the book, The Three Hostages, written in 1924.

The hostages present a difficult problem for Hannay.  The man who is holding them is a Very Bad Man.  Luckily, Hannay gets some advice from an older and wiser friend:

A very wise man once said to me that in this life, you could often get success, if you didn’t want victory. In this case, we’re out for success only.  We want to release the hostages.  Victory we can never hope for….we’ll never connect Medina [the bad guy] with this thing.

My lesson: We can’t achieve victory about Vermont Yankee, either.  For example, there’s a meeting at one of the local churches later this month.  Various anti-nuclear groups are gathering to plan “non-violent direct action“  under the aegis of the Clamshell Alliance. They are holding an overnight-camp training session, and they plan to “act” if Vermont Yankee wins the lawsuit.

Sometimes, sometimes I think that Entergy will win the lawsuit.  Sometimes I think it will soon be time to stop advocating for nuclear energy, and maybe write a book about Vermont Yankee.  Sometimes, I imagine Victory.

But, as Hannay’s friend explained:  hoping for Victory can get in the way of achieving Success.

Everybody Matters or Nobody Matters.  My Second Lesson.

Michael Connolly wrote a series of novels about a Los Angeles Police Department detective named Harry Bosch. The character’s real name is Hieronymus Bosch because the detective’s mother, a prostitute, was impressed by the Dutch painter’s nightmarish paintings.  Detective Harry is a hard-boiled guy with a heart of gold.

Harry investigates homicides of prostitutes, drug addicts, and homeless veterans.   At one point, he was a private detective, but he returns to the police.  When asked why he stays in the police job, investigating such deaths, he answers:

Because everybody matters, or nobody matters.

My lesson:  Being for conservation and ignoring nuclear would be an easy life for me.  I am active in my town’s Energy Committee. We write proposals for new street lights and discuss whether we need another “Button Up Vermont” workshop in town. (No, we don’t. There was poor attendance at the last one. )

I could be considered a cheerful matron and a civic volunteer—without nuclear.

Instead, many people in town find me difficult, because I advocate for Vermont Yankee.  Still,  I have to do this.  Harry Bosch and I are birds of a feather.  “Everybody matters, or nobody matters”. My version: “Reducing all CO2 emissions matter, or no CO2 emissions matter.”  We can’t have “CO2 emissions from incandescent bulbs matter, but replacing Vermont Yankee with fossil fuels doesn’t matter.”

Harry Bosch and I have similar philosophies.  Too bad he’s a fictional character.

It All Happens in a Village: My Third Lesson

My final lesson is from the estimable Miss Marple of Agatha Christie.  She solves crimes because, after all, the criminals remind her of people in her village.  As Wikipedia puts it:

Miss Marple is able to solve difficult crimes… because St. Mary Mead…has given her seemingly infinite examples of the negative side of human nature.

My Lesson: Everything is local, and one must grow where one is planted.  That’s why I defend Vermont Yankee.  It is a local issue, and that would be enough.  It may also have national implications, but that is perhaps less important.

Grow where you are planted.

Tomatoes and Novels

Speaking of planting, it’s time for me to go out and pick some tomatoes for dinner. And settle in with my next novel.  What shall I read?

It’s the kind of choice I am capable of making, during the dog days.

66th Carnival of Nuclear Energy Bloggers

Box Scores

  • Southern, Vogtle, and Westinghouse advance in standings
  • Rowe 1, Nukes 0
  • TVA 1, Zombies 0

There was good news and bad this week in the field of nuclear energy, at least in the U.S.  The good news is that the U.S. Nuclear Regulatory Commission pushed out the final safety evaluation reports not only for the licenses to build and operate four new reactors, but also for the reactor design to be used by them.  The reactor projects are Southern’s Vogtle site in Georgia and Scana’s V.C. Summer station in South Caroline.  Both projects reference the Westinghouse 1,100 MW AP1000 light water reactor.

Rowe has bad news for new nukes

The bad news is that Exelon CEO John Rowe delivered another of his “no profits in new nuclear construction” speeches.  That’s distinct from up rates or getting more production of electricity from the existing fleet.

John Rowe, CEO Exelon

According to World Nuclear News, Rowe spoke at the American Nuclear Society’s 2011 Utility Working Conference in Hollywood, Florida, on 15 August, Rowe said that the renaissance of the US nuclear industry is being limited by economics rather than technology.

“The near-term prospects for an expansion in the use of nuclear energy in the USA “will be miserably hard and extremely challenged by economics,” according to the head of Exelon, the country’s largest nuclear utility.

“When making decisions about what to build, the same standards that we say should be applied to renewable, coal and gas must be applied to nuclear.” These include costs, energy demand, energy security and government support. “Politicians ignore many of these factors, especially economics, and want to promote their favorite technologies.”

The first is that we have the right technology. He said that new designs needed more safety features and to be simpler to operate than earlier designs. “The new reactor designs have made great progress in this area, and this condition has been met,” Rowe concluded.

The second requirement is to have a workable solution for dealing with radioactive waste. However, he said, “Unfortunately the federal government is further away from keeping its promise on waste disposal than ever and this condition cannot be met.”

Thirdly, there needs to be demand for new generating capacity. “There is not currently a need for new baseload generation because of minimal load growth and excess generation capacity,” Rowe said. “This could change with more coal plant retirements, but right now this condition cannot be met.”

The final precondition is that there are consistently higher prices for gas, making nuclear a more economical option. However, he noted that new supplies of natural gas “has caused prices to plummet from their historic highs. It is the most affordable fuel for at least one, perhaps two decades.” Therefore, “This condition cannot be met due to the influx of shale gas into the market.” Rowe added, “Shale is good for the country, bad for new nuclear development.”

Margaret Harding has a review of Rowe’s speech at her blog ~ 4 Factor Consulting.

It might not be what we want to hear, but we, as an industry, need to listen. If the CEO of the biggest merchant nuclear fleet in the US is telling us why nuclear isn’t the answer, we need to understand his message and figure out how to change the equation. Not shoot the messenger for telling us the bad news.

Not said in my piece, but I started at GE Nuclear in 1981, three months after Jack Welch came to the corporate HQ and gave them a tough dose of reality. The business plan to sell three plants a year was not based in any factual assessment and required a complete revision to the reality of that market. As much as I might dislike Jack, he was right. John Rowe is giving us a similar assessment. We need to listen.

Also, Rod Adams at Atomic Insights, has additional observations about Rowe’s speech. Is Rowe right? Will natural gas remain cheap for 10-20 years?

When I was trying to sell investors on the idea of building small modular reactors in the 1990s, people told me that natural gas was cheap and would be cheap forever. The EIA projections backed up those assertions. In 1996, when I put Adams Atomic Engines, Inc. to sleep for the first time, natural gas was selling for $1.60 per million BTU in the US.

In the summer of 2008, after a long climb, natural gas topped out at about $14 per million BTU in the US. The rate of increase over that period of time was substantially higher than the EIA’s 1996 projection of 2-3 percent per year.

TVA turns back zombie attacks at Bellefonte

One final piece of good news is that the Tennessee Valley Authority, which does not depend on the merchant model, decided to proceed with completion of construction of the 1,260 MW Bellefonte nuclear reactor in northern Alabama. The reactor will proceed under the old Part 50 licensing process with a construction license and then an operating license.  Brian Wang has a link to TVA’s press release.

Anti-nuclear groups labeled Bellefonte a “zombie plant,” and dressed up in theatrical makeup to add emphasis to their cause, but the TVA board banned costumed speakers from its meeting.  The board’s unanimous vote should be a confidence builder for anyone following the plant’s progress.

This week’s Carnival

At ~ Next Big Future ~ there is an update on small fusion projects – Helion Energy, General Fusion and Tri-alpha energy.  Helion Energy has already received $5 million in funding from NASA and the US Department of Defense among others, is now looking for $20 million from private investors to build what it says could be a commercially viable reactor.

The first laboratory tests of the General Fusion (magnetized target fusion) design have gone well, achieving a temperature of 5 million degrees for 1 microsecond. Tri Alpha Energy, a secretive California-based company, is believed to have raised $90 million for its variant of the field-reversed technique; among its investors is Microsoft co-founder Paul Allen.

John Bickel ~ Evergreen Nuclear – looks back at pro-nuclear talking points for the Seabrook Nuclear power station and finds they have aged will with time.

Charles Barton ~ NuclearGreen ~ has two reports.

The first post focuses on motives for the British Campaign for Nuclear Disarmament during the 1950′s.  In particular it argues that the British Nuclear arms program failed to enhance British National security, while creating a nuclear safety problem and other serious concerns, and reflected ambitions of politicians that had little to do with the well being of the British people.

The second post is a transcript of a 1959 speech by Alvin Weinberg and is cross posted from Energy from Thorium. It is an important and highly relevant statement of the future role nuclear energy can and should play in promoting human well being.

CoolHandNuke – more good news about nuclear energy – in the latest in a continuing series, the site publishes more updates designed to inspire and lift the spirit when it comes to the outlook for nuclear energy.

Meredith Angwin ~ Yes Vermont Yankee ~ says maverick U.S. Senator Bernie Sanders is the sole vote against Small Nuclear Reactors (SMRs).

Senator Bernie Sanders usually says he is against Vermont Yankee because it is run by Entergy and the plant is old and dangerous (in his opinion, at least). However, Sanders is equally against new plants. In a recent bi-partisan Senate Committee vote, Sanders was the only vote against research funding for small modular rectors. Sanders just doesn’t like nuclear energy in any form.

Gail Marcus ~ Nuke Power Talk ~ says spot lighting the facts about failures at Fukushima doesn’t make someone “anti-Japanese.”

In response to a reader’s assertion that her previous posts on Japan have sounded anti-Japanese, she speculates on possible reasons for some of the revelations that have come out in the press about the behavior of the Japanese nuclear organizations, both in the wake of Fukushima and in other instances.  She concludes that, while such behavior may have cultural roots, awareness of the downsides of the actions can cause people and organizations to change their behavior.

Dan Yurman ~ Idaho Samizdat ~ USEC’s American Centrifuge project is at a standstill.  The firm has not yet obtained a $2 billion Department of Energy loan guarantee. While the firm’s investors are patient, that won’t last forever.

At the ANS Nuclear Cafe, Yurman has a review of Saudi Arabia’s nuclear energy ambitions.  While the 16 reactors the Kingdom of Saudi Arabia (KSA) wants to build will likely be located at coastal sites, the electricity from them will support development of the “empty quarter” and turn KSA into a regional exporter of energy to Oman and other Persian Gulf states.

TVA approves completion of Bellefonte

The utility’s board of directors will spend $4 billion–$5 billion completing the 1,260 MW reactor

by Dan Yurman

Tom Kilgore, TVA CEO

In a unanimous vote on August 18, the board of directors of the Tennessee Valley Authority (TVA) voted to finish construction of the Bellefonte nuclear reactor located in northeast Alabama. The vote followed a three-hour meeting that heard from 50 people. TVA chief executive officer Tom Kilgore said that completing the project is the right move for the utility’s nine million rate payers. It will provide needed electricity to the region without adding to carbon emissions.

“With today’s action, TVA will add more clean energy from nuclear sources to its generating fleet,” Kilgore said. He added that the decision implements a key element of the utility’s Integrated Resource Plan.

In response to comments from about 50 people during the meeting, Kilgore said that the board has been fully engaged in understanding safety issues related to the events that took place in Fukushima, Japan, last March.

“As we build Bellefonte we will integrate safety modifications from an extensive review of the lessons learned from Fukushima. Making Bellefonte a productive asset, with state of the art equipment, will add to TVA’s generating mix.”

The Bellefonte plant is one of two reactors started in the 1980s, but which were never completed due to low electricity demand. Much of the original equipment was subsequently removed from the plant. New pumps, pipes, and a digital control room are on tap for the completion of the project.

The construction phase of the project, which will begin after TVA completes the Watts Bar-2 reactor in 2013, will generate about 2,800 jobs and 650 permanent positions. It is expected to enter revenue service by 2020.

How TVA will pay for Bellefonte

In a press conference following the board meeting, John Thomas, TVA’s chief financial officer, said that TVA will raise the funds to pay for completing Bellefonte without busting through the utility’s debt ceiling. Instead of issuing bonds for the estimated $4.9 billion in costs, TVA will finance it by leasing two power stations that will be completed by 2013. The first is the Watts Bar-2 reactor and the other is a gas-fired plant.

Thomas said that the way the deal will work is that investors who buy Watts Bar will then lease it back to TVA. Thomas added that the lease-back arrangement will be cheaper for rate payers than having to cover the cost of interest on bonds.

Another financial measure is that TVA will not begin the construction phase at Bellefonte until the Watts Bar plant is completed in 2013. This way, TVA will have only one nuclear reactor under construction at a time. Board member Mike Duncan and CEO Tom Kilgore made the case to the board that this approach would prevent distractions and keep the utility fully focused on both projects with enough time to deal with both of them.

No zombies please

Opponents of the decisions included environmental groups who called the Bellefonte project a “zombie reactor” and paraded outside the meeting dressed up in theatrical makeup. The utility banned anyone wearing these costumes from entering the hearing room to avoid disruptions.

Don Safer, who was not dressed as a zombie, and represented the Tennessee Environmental Council, testified before the board. He ticked off a list of consequences if there was ever an accident at the reactor. Other speakers accused the board of lying about the safety measures that would be imposed on plant operations.

On the pro-nuclear side,  Doug Walters, vice president for regulatory affairs at the Nuclear Energy Institute, told the TVA board that the all new components Bellefonte will be one of the nation’s “most advanced reactors.”

The anticipated completion of Bellefonte has even inspired artists. Suzy Hobbs, a painter and sculptor who has followed the issue, said that she’d like to see TVA paint the cooling towers and offered an artist’s rendition (right) of how they would look.

Saudi Arabia’s nuclear energy ambitions

Curbing domestic oil use is a key driver

By Dan Yurman

The Kingdom of Saudi Arabia (KSA) plans to build 16 nuclear reactors over the next 20 years spending an estimated $7 billion on each plant. The $112 billion investment, which includes capacity to become a regional exporter of electricity, will provide one-fifth of the Kingdom’s electricity for industrial and residential use and, critically, for desalinization of sea water.

This past April, the Saudi government announced the development of a nuclear city to train and house the technical workforce that will be needed to achieve these ambitions. It is clear that KSA’s plans for spending its sovereign wealth fund will be mostly focused on the home front.

At the same time, a former Saudi ambassador to the United States , Prince Turki al-Faisal (served 2005-2006), has warned that a regional nuclear arms race could start if Iran does not curb its nuclear efforts. He told the Wall Street Journal on July 20, “It is in our interest that Iran does not develop a nuclear weapon, for their doing so would compel Saudi Arabia … to pursue policies that could lead to untold and possibly dramatic consequences.”

According to the WSJ, the Saudi government said the former ambassador does not speak for it in an official capacity. Al-Faisal, however, is widely believed to be on a short list to be the next foreign minister of KSA. How credible his claim is about the potential for a regional arms race remains to be seen.

Swapping nukes for oil drums

The main driver for KSA’s plans to build reactors is that at the rate that it is burning its own oil, it may have substantially less to export in just a decade or so. At a minimum, it may lose the excess capacity the rest of the world relies on when there are disruptions in supplies from other countries. One scenario suggested by energy analysts that follow oil markets is that within two decades most of the KSA output would be used for domestic consumption.

Total Saudi reserves are estimated at 267 billion barrels. Debates rage in the news media over so-called peak oil, but energy experts discount them as speculative at best, and fantastic or worse on the downside.

Current production estimates put total KSA production capacity at 12.5 million barrels a day with a maximum output of 15 million barrels a day. The Wall Street Journal reported in April 2011 that production was running at 8 million-9 million barrels a day compared to 11 million barrels a day in 2010 reported by the Energy Information Administration. The difference is the global economic downturn has reduced demand. What’s got the attention of energy planners is that domestic use in KSA could grow from 3.4 million barrels of oil a day in 2009 to 8.3 million barrels a day by 2028.

The official Saudi press agency said in April 2010 that it was “alarmed” by increasing oil and gas consumption for domestic use and the resulting impact on export revenues. Reduction of consumption, which pushes up use of fossil fuel to produce electricity, is not an option for both economic and political reasons. In 2011, the Saudi government has increased its subsidies of energy supplies by $100 million for domestic use, in part to dampen any possibilities of social unrest like that which toppled regimes in Tunisia and Egypt.

Like other Arab countries, KSA has a large population of unemployed young people who have better than average educations.  This is a volatile mix and the arch conservatives that run KSA have defused it with lavish subsidies.

Electricity demand is predicted to increase from 75 GWe by 2018 to more than 120 Gwe by 2030. This growth can’t be sustained by fossil fuel alone and also maintain the income stream the nation depends on from oil exports. Nuclear reactors are an obvious choice to intervene in an unsustainable growth scenario.

Saudia Arabia will likely locate its nuclear reactors at coastal sites to facilitate delivery of large components and desalinization operations. (Map: CIA World Fact Book)

This outlook is sending the Saudi government down a path to develop nuclear

energy. In April, it announced that it was setting up the King Abdullah City for Atomic and Renewable Energy (KA-CARE) to pursue this objective. Saudi Arabia is building up its transmission and distribution grids to interconnect with the UAE on the east and Oman to the south.  It is developing its so-called empty quarter which Middle East experts point out isn’t as empty as it sounds.

The new city’s charter states that nuclear and renewable energies, especially solar, would be developed to ensure continued supplies of drinking water and electricity to its growing population and save hydrocarbon resources such as petroleum and gas for use by future generations. The objective is to make them a source of income for a much longer period.

The 16 reactors KSA plans to build will be part of a strategy of being a regional exporter of electricity as well as meeting its own needs. Most likely, the reactor locations will be along the Red Sea or Persian Gulf coastlines.

Nuclear imports will depend on diplomacy

Executing a plan to build 16 nuclear reactors will require lots of help from other countries. In 2008, a memorandum of understanding was signed with the United States, but there is no agreement under Sec.123 of the Atomic Energy Act that would allow U.S. firms to sell nuclear technology to KSA. There are concerns in Congress that doing so wouldn’t be a good idea.

Rep. Illena Ros-Lehtinen (R., Fla.) is a hawk on U.S. relations with Iran and opposed to inking a 1-2-3 agreement with Saudia Arabia

U.S. Rep. Illena Ros-Lehtinen(R., Fla.), a hawk on containing Iran and the chair of the House Foreign Affairs Committee, told the WSJ on July 30 that she thinks selling nuclear reactor technology to KSA is a bad idea.

“I’m astonished that the administration is even considering a nuclear cooperation agreement with Saudi Arabia,” she said.

She added that she thinks it is an “unstable country in an unstable region.”

Her chief sticking point is the statement by former ambassador al-Faisal about the possibility of developing nuclear weapons if Iran doesn’t curb its program.

Is it 1-2-3 or three strikes you’re out?

The Obama administration would like to see a 1-2-3 agreement with Saudi Arabia along the lines of the one it signed with the UAE, which committed to reliable fuel services rather than developing its own enrichment capabilities. The UAE has been touted as a model for other nations as it has inked a $20-billion contract with South Korea to build four nuclear reactors. The United States has sought to ink similar deals with Jordan and Vietnam, but these discussions are not bearing fruit.

According to Mark Hibbs, a nuclear energy analyst with the Carnegie Endowment for International Peace, the lack of a 1-2-3 agreement with the United States could impact Saudi Arabia’s ability to import nuclear technologies from other nations. France and Japan would not transfer enrichment and reprocessing technologies to Saudi Arabia, as in December 2009, both of these countries, along with the United States and the other members of the G8, pledged indefinitely not to export these items to newcomer countries.

In any case, Hibbs notes that Saudi Arabia has only a limited nuclear engineering workforce and lacks enrichment and related fuel-cycle facilities. This means that claims by its political leaders that it might be part of a regional nuclear arms race are diplomatic posturing but not credible threats.  It would be no surprise that Iran has probably made this assessment as well.

Hashim Abdullah Yamani is in charge of building Saudi Arabia's new nuclear city

Interestingly, the same Prince Turki al-Faisal who engaged in some diplomatic sabre rattling in his comments to the Wall Street Journal also has a lot of influence over Saudi Arabia’s new nuclear city.

The Financial Times reported that the man in charge of the nuclear city project is Hashim Abdullah Yamani, who previously headed ministries for commerce, trade, and electricity. While it may be that the country won’t get its own enrichment facilities, it could import reactors and sign on to reliable fuel services without ever inking a 1-2-3 agreement with the United States.  That doesn’t mean U.S. firms won’t seek market share in the new build.

U.S. firms seek a piece of the pie

In August 2010, one of the biggest export deals that few ever heard of was announced by Chicago-based Exelon Corp. (a nuclear utility), The Shaw Group, and Toshiba, to build nuclear reactors in Saudi Arabia. Toshiba and Shaw would provide the reactors and the construction expertise, while Exelon would operate the reactors once they are built.

Under the terms of the agreement, the group jointly would pursue engineering, procurement, construction, and operations of nuclear power plants using Toshiba’s Advanced Boiling Water Reactor (ABWR), which is a leading-edge nuclear power plant technology with already proven records of performance, reliability, and operation in Japan. The group also is capable of utilizing Westinghouse AP1000 technology.

Like any other deal along these lines, the Saudi government would have to execute a 1-2-3 agreement with the United States to make it work.  With House Republicans likely lined up against it, President Obama will have to make some political magic to get a deal. So far the intractability of the House on just about anything the White House asks for does not bode well for U.S. firms seeking to enter the Saudi nuclear market, at least before the 2012 election.

Up, Up, and Away: Victor Hess and the Cosmic Ray

By Paul Bowersox

Victor Francis Hess was awarded a Nobel Prize in physics for discovering “cosmic rays.” Hess did some of his research in a very bold manner—here’s some of his story.

A strange case of atmospheric ionizing radiation

Ionizing radiation is very potent, as radiation goes, because it has sufficient energy to knock electrons off of atoms or molecules—thus producing positively-charged ions. Ions can also be negatively-charged, such as when a free electron is caught by an atom or molecule—and ions can even be formed by adding other ions.

This “ionizing radiation” was known and measurable in the early 1900s, but the results of some measurements were not as expected. The newly-invented instruments of the time—electrometers, which could detect the presence of energetic charged particles—had been used to detect many radiation sources at ground level. Naturally, moving away from these ground-based radiation sources should  have resulted in lower electrometer readings.

Instead, early experiments, such as Theodor Wulf’s taking his new electrometer to the top of the Eiffel Tower, seemed to indicate that ionizing radiation in the atmosphere increased at levels above the (radioactive) ground. These results were definitely not well accepted by scientific authorities at the time.

Enter Victor Hess

Hess

Victor Hess was very interested in this puzzle. He improved the accuracy and endurance of Wulf’s electrometer, then put this new equipment to good use by taking measurements of charged particles in the atmosphere—from the gondola of a balloon! These were no ordinary balloon excursions. Both during the day and night, in 1911 and 1912, Hess measured ionizing radiation at altitudes up to 3 miles high. A risky endeavor at the time.

Hess’s work showed that, as one ascended above the surface of the earth, the level of radiation at first decreased just as expected. Then, radiation levels began to increase with increasing altitude—reaching several times that of ground level at Hess’s maximum attainable altitude of about 3 miles.

Hess and his balloon

Hess even made an ascent during a solar eclipse, to rule out the sun as the source of the radiation. With the moon blocking most of the sun’s radiation, levels of radiation in the atmosphere still increased at higher altitudes. Hess could only conclude that the atmospheric radiation came from outer space, and eventually came to be known as cosmic rays.

Cosmic rays

Most cosmic rays are actually protons (hydrogen nuclei without an electron), while about 10 percent are alpha particles (helium nuclei without electrons), 1 percent are heavier charged particles, and most of the remainder are solitary electrons. Also, a small fraction of cosmic rays are antimatter particles.

The earth’s atmosphere does a good job of protecting us on the surface from cosmic rays—and this is fortunate, since some cosmic rays have energies much greater than can even be created with the largest particle accelerators. Cosmic rays interact in the atmosphere to create secondary radiation, including x-rays, muons, protons, alpha particles, pions, electrons, and neutrons.

 

 

 

 

 

 

 

In spite of the atmosphere’s shielding, cosmic rays are still a substantial portion of the natural background radiation that the earth experiences every day.

The effects of cosmic rays explain why airline flight crew workers receive more radiation dose on average than any other worker. Fortunately, for eons our distant ancestors flourished in our (mildly) radioactive environment on earth—equipped  with the ability to successfully repair the occasional damage from ionizing radiation.

Some of the sources of cosmic rays are well understood, including processes occurring in other stars like our sun. Other sources of cosmic rays are unknown and a matter of ongoing research. Hess’s discovery of cosmic rays led to an era of new discoveries in particle physics that still continues. After receiving his Nobel Prize in 1936, he continued a long and outstanding career of research into nuclear physics, radioactivity, and its effects.

Two members named ANS Fellows

Two members of the American Nuclear Society were named Fellows during the June 2011 ANS annual conference. These awards were presented in recognition of the Fellows’ significant contributions and achievements to nuclear science and technology.

Hibiki

The new ANS Fellows are:

Takashi Hibiki, for his extensive and outstanding original research contributions to nuclear thermal-hydraulics, two-phase flow modeling, and two-phase flow instrumentation.

 

Nanstad

Randy K. Nanstad, for his internationally recognized expertise on the effects of irradiation on fracture behavior of reactor pressure vessel steels. His ground-breaking research includes the design and conduct of large national irradiation programs, development and analysis of extensive irradiation effects databases, and critical contributions to our understanding of embrittlement mechanisms.

 

The honored membership grade of Fellow is  awarded to ANS members for outstanding accomplishment in any one of the areas of nuclear science and engineering.  The two new Fellows will be listed with their peers on the ANS Web site.
