“Nuclear Medicine” – National Nuclear Science Week, Day 5 (October 24)

NSWlogoThe fifth and final day of Nuclear Science Week is all about Nuclear Medicine. Have you ever experienced a procedure at a hospital that employed radiation? Did you know that there are actually many different ways that nuclear technology is employed in medicine—and not just at your local hospitals?

According to the American Nuclear Society’s Center for Nuclear Science and Technology Information:

Nuclear medicine and radiology are the whole of medical techniques that involve radiation or radioactivity to diagnose, treat and prevent disease. While radiology have been used for close to a century, “nuclear medicine” began approximately 50 years ago. Today, about one-third of all procedures used in modern hospitals involve radiation or radioactivity. These procedures are among the best and most effective life-saving tools available, they are safe and painless and don’t require anesthesia, and they are helpful to a broad span of medical specialties, from pediatrics to cardiology to psychiatry.

You can learn much more about nuclear medicine at the dedicated CNSTI page on the topic—click here to access it.

The US Nuclear Regulatory Commission has oversight over some, but not all, medical uses of nuclear material and technology. To read about the NRC’s role and to see what it regulates, click here.

The US Food and Drug Administration regulates a portion of the medical field that uses radioactivity; click here to access the FDA’s extensive site portal covering all aspects of what it regulates. You can also find many other useful resources at this link.

“Nuclear Safety” – National Nuclear Science Week, Day 4 (October 23)

NSWlogoDay 4 of the annual National Nuclear Science week is all about Nuclear Safety.

The use of either fission of atoms, or decay of radioisotopes to benefit man (whether that benefit derives from the production of electricity, the diagnosis of a medical patient, the preservation of food, or many other things) brings along with it a serious responsibility to ensure the safety of not only all involved with the process but those uninvolved as well. To this end, a tremendous amount both of time and money are spent by all organizations designing, operating, or using nuclear technology as well as governmental oversight agencies (often called “regulators,” such as the US Nuclear Regulatory Commission.)

The American Nuclear Society’s Center for Nuclear Science and Technology Information has a great page covering the many, varied aspects of nuclear technology safety. Click here to access this CNSTI page.

Don’t forget—you can visit the Nuclear Science Week official website for much more information, including lesson plans, and other resources.

“Nuclear Energy” – National Nuclear Science Week, Day 3 (October 22)

NSWlogoThe third day of National Nuclear Science Week is focused upon the production of energy by nuclear means—and that means energy that can do work for man. Electric power, steam for heating businesses and homes, and mechanical power for propelling ships are perhaps the best known examples of man’s use of nuclear energy.

Regardless of model or type, all nuclear reactors produce heat; this is how we get useful work from them. In the case of a nuclear power plant, the heat is used to boil water into steam, which then is used to run very large turbines; these generate power for thousands of businesses, homes, street lights, traffic lights—everything you see that receives electric power. And did we say “large?” A typical turbine generator at a nuclear plant can be 200 feet long; the parts inside the turbine that rotate can have a total mass of around 700 tons, and the machine overall can develop from 900 MW (megawatts) to 1400 MW. That’s well over one million horsepower!

You can read about nuclear energy in an introductory fashion at the American Nuclear Society’s CNSTI page on Reactors, a special part of the Nuclear Science Week publications.

The U.S. government has two primary offices related to nuclear energy. The Department of Energy’s Office of Nuclear Energy develops and promotes nuclear power technologies, while the Nuclear Regulatory Commission has the responsibility of oversight of all nuclear facilities in the United States.

For more information on the development of nuclear energy:

The path to developing useful work from splitting the atom (known as “fission”) began with Enrico Fermi’s “atomic pile,” the CP-1, which was the first working nuclear reactor. Click here to read about the effort, and its 70th anniversary.

The first full-scale nuclear reactor of any sort was actually not used for power production, but rather was part of the US Manhattan Project. Still, this complicated and large machine proved out concepts that would be used in power reactors. Click here to read about this reactor, the Hanford B Reactor.

The first nuclear reactor plant intended for the production of useful power alone (propulsion and electricity) was the STR Mark I, which was the prototype or dress rehearsal for the world’s first nuclear powered vessel, USS NAUTILUS.  See some details of the prototype’s construction at this link.

“Careers in Nuclear” – National Nuclear Science Week, Day 2 (October 21)

NSWlogoThe second day of National Nuclear Science Week promotes the knowledge of careers in nuclear-related fields.

For most people, the idea of a career in a nuclear-related field might evoke images of the production of electricity by nuclear energy. While that field has a very large number of associated practices, there are many other nuclear-related disciplines. How many times have you passed by, or perhaps even been a patient in, a Nuclear Medicine department of a hospital? Have you ever heard of the use of nuclear technology to evaluate materials? Did you know that nuclear technology can help with the long-term preservation of food items? These are only a few areas of life wherein nuclear technologies are of great benefit to mankind.

The American Nuclear Society’s Center for Nuclear Science and Technology Information has a great resource page on nuclear careers; click here to see it. You might be amazed by the number of points of our lives that are touched by nuclear technologies and made better by having been.

“Get to Know Nuclear” – National Nuclear Science Week 2014, Day One

NSWlogoMonday, October 20, marks the first official day of National Nuclear Science Week—a week long, annual coordinated educational event that promotes nuclear science and technology.

Five years ago the Smithsonian Affiliated National Museum of Nuclear Science and History founded this nationally recognized, week-long celebration. Nuclear Science Week is a unique outreach opportunity that grants teachers, students, and the general public direct access to nuclear technologies and energy experts. A basic introduction to the concept, as well as details of its execution, can be found here.

Each day of the NNSW focuses on a specific theme, and as an introduction the first day is designated as “Get to Know Nuclear.” You might be surprised how many facets of our lives are touched, and enhanced, by nuclear technologies—and you might be surprised how many people know little or nothing about these nuclear technologies. Fortunately, there are a number of great, easy-to-read official sources you can consult if you’re an educator tasked with presenting such material or even if you’re just personally curious.

The American Nuclear Society’s Center for Nuclear Science and Technology Information has set up a special section on National Nuclear Science Week, which can be found here. There is a specially dedicated section for the first day, “Get to Know Nuclear.” ANS also has a variety of educational materials available at this link.

National Nuclear Science Week has its own dedicated stand-alone website, found here, which is presented by the National Museum of Nuclear Science. A schedule of various events throughout the week can be found here.

They Harnessed the ATOM – the first Navy prototype nuclear plant

By Will Davis

This past week, a remarkable article was printed in The Atlantic, which gave a full first-person account of the initial trial run of the STR Mark I nuclear prototype plant—the plant that paved the way for the success of the first nuclear powered vessel ever built, the submarine USS NAUTILUS.

At the time this prototype plant was built in the Idaho desert, at what was at that time called the National Reactor Testing Station (NRTS), there was actually a rather remarkable amount of information provided to the public about the plant—mostly in terms of photographs of the plant, if not anything in any real technical detail. Let’s take a look at some of the unclassified views released to the public and published in widely available resources, along with a few details of the plant’s history.

S1WatNRTSJan201954

The photograph above was released January 20, 1954, and was both distributed by wire photo channels (you are seeing a scan of an original photo) and was published in a remarkable PR brochure entitled “They Harnessed the ATOM,” which you’ll see more of shortly. This is the STR Mark I prototype at NRTS Idaho Falls; “STR” stood for “Submarine Thermal Reactor,” the original designation for this plant that was later redesignated “S1W” for “Submarine, First design, Westinghouse.” At the time this plant was constructed, its designer, the Bettis Atomic Power Laboratory, was operated by Westinghouse for the U.S. government—hence the “W” designation. This of course is the plant whose operation was detailed in the article linked above.

STR Mark I door

Above, the front cover of the brochure “They Harnessed the ATOM” that shows a view into the open door of the STR Mark I prototype. The simulated submarine hull is clearly visible, as is the large tank of water at the opposite end that surrounded the reactor compartment and that was used for shielding.

STR Mark I inside

Inside “They Harnessed the ATOM” is this view (above) looking down onto the STR Mark I prototype power plant. The power plant of course developed a fair amount of waste heat, which had to be dissipated; in these early days, cooling towers were not used but rather spray ponds. The spray pond for STR Mark I is seen below, also from this brochure. The pond, it was said, held 2 million gallons of water and could cool 22 500 gallons of water per minute.

STR Mark I spray pond

Another publication of that time that featured photos and some scant details on the construction of this prototype was “Selected Articles on Nuclear Power,” which took several articles that had appeared in the Westinghouse employee magazine “The Westinghouse Engineer” and republished them essentially as an advertising brochure—although this one was much more pointed at industry than the previous one shown, which was pointed at the general public. Inside the front cover of “Selected Articles,” we find the illustration seen below.

STR Mark I Selected Articles

The upper part of the illustration is a view similar to, but not identical with, that seen earlier while the lower appears to show a student examining a model of the power plant. Naturally, the model is an exterior model only (not a cutaway) and shows no real details of the nature of the construction of the nuclear steam supply system, propulsion or control equipment, or actual plant arrangement.

Inside this publication is an interesting and concise timeline of use to historians:

Timetable of Submarine Thermal Reactor Project

• April 1948 – Formal project established at Argonne National Laboratory

• June 1948 – Original Navy-Westinghouse contract

• December 1948 – Original AEC–Westinghouse contract

• March 1950 – Occupancy of new facilities at Bettis Site

• August 1950 – Commencement of STR Mark I construction, National Reactor Testing Station, Idaho

• August 1951 – Award of NAUTILUS construction contract to Electric Boat Division, General Dynamics Corporation

• June 1952 – Keel plate laying of USS NAUTILUS (SSN-571)

• March 1953 – First critical operation of STR Mark I prototype plant

• January 1954 – Launching of USS NAUTILUS

• September 1954 – Commissioning of USS NAUTILUS

As can be seen from the timetable above, time was of the essence for the prototype power plant, as the keel for the operational submarine (which would house the plant designated STR Mark II) had already been laid down less than a year before the first startup of the prototype reactor. As is so vividly described in the Atlantic account, the actual prototype’s design was already well up the learning curve and the performance so satisfactory that NAUTILUS went to sea confident in its ability to perform. Of course, Admiral Rickover’s choice to build the first prototype plant as a simulated, land-locked submarine section in order to prove out not just concept but physical construction was exactly correct. A similar design process—use of an actual power plant design that could be duplicated perfectly for a production submarine—was employed for the Submarine Intermediate Reactor Mark I, built thousands of miles away to test principles for what would become USS SEAWOLF at the same time.

From the brochure "The Seawolf Story," Knolls Atomic Power Laboratory.  "In the early morning of March 20, 1954, the prototype power plant of the Seawolf was 'launched' into its location in the 225 ft. diameter steel sphere located at the West Milton Site of the Knolls Atomic Power Laboratory."

What happened to STR Mark I, later known as S1W? The plant operated for decades, as an integral part of Admiral Rickover’s system that insisted that Navy nuclear propulsion personnel obtain qualification on a land-based plant before being assigned to a nuclear powered ship or submarine. The plant finally shut down for the last time in October 1989.

It may be difficult to imagine today that photos such as we have seen were released, but several of these have actually circulated fairly widely. In fact, it would certainly appear that India took notice of the design of these early submarine prototype plants; look at the links below, and note the overall, external design of the prototype plant for the first Indian nuclear submarines.

Changing How We Communicate

Preface: Robert Rock, a Canadian professional who authored the post you’re about to read, is relatively new to the field of nuclear communications but isn’t new to communications overall. I believe it’s good to get outside perspectives once in a while—they make us think about and reflect upon our own actions. I hope that his piece, specifically written for us here at ANS Nuclear Cafe, can provoke some discussion and help us develop new perspective. Your Editor, Will Davis.

••••••••

Changing how we communicate.

by Robert Rock

Participating in a LinkedIn Group called Cool Hand Nuke got me to thinking of the movie that it wittily takes its name from—Cool Hand Luke. Specifically, one of the movie’s most famous quotes, “What we have here is … a failure to communicate”

I think that quote sums up the nuclear industry both at the moment and over the last few decades.

Right now, I see a large amount of people looking for safe, cheap, non-carbon emitting energy, which can produce a large amount of power reliably. Dear nuclear crowd, doesn’t that describe nuclear energy? How have we not been able to tap into this desire?

Why haven’t we?

By the very nature of the nuclear industry, we are heavily weighted toward scientists, engineers, and other technical professionals. This is exactly what the industry needs to continue its great track record of safety and reliability.

The flip side is that there are far too few people who are professional communicators. We need these professionals in our industry as well as to improve our ability to connect with our audience.

An analogy that I often hear in the nuclear industry is that we aren’t building 1970s reactors anymore. Why do we still want to communicate like it’s the 1970s?

Communications 101

First, we need to define our audience. In my personal opinion, we have two major audiences for our message, but they’re very closely linked—the general public and politicians. They’re linked because politicians can move forward on new nuclear build without public support, while the public won’t demand new nuclear from politicians without knowledge of the industry.

Next is our message. As an industry, the question is do we have a clear, concise message that we all believe in? If we do, then I’ve never heard it. We desperately need to develop that message, but we have to develop that message with our audience in mind. It has to connect to them and satisfy their “what’s in it for me” desire. We won’t get it right the first time out and that’s okay. We need to experiment, learn from other industries, and have some trial and error. This process will improve our connection to the audience.

Finally, after we know our audience and our message, we now need to define the ways that the audience wants us to relay that message to them. That could be social media, blogs, videos, infographics, radio, TV, a combination of some, or all of the above. Again we need to experiment and constantly review the impact that each method has had in reaching the audience.

Our current society has had an explosion in the amount and variety of ways that we are communicating with one another. We “talk” to one another over email, we text, we participate in online groups in Facebook, Google, and LinkedIn, we tweet each other, we watch videos on YouTube, and sometimes we use Skype to have a conversation “face to face”.

Changing how we communicate

Taking the 101 and mapping it out, we see the components of communication. The most common problem on the sender side of the message is that what they want to say and what they end up saying is often very complex and often not even totally clear to themselves. The message of the industry is filled with technical information, acronyms, and the science of nuclear. Will our desired audience understand the message? Are we delivering the message using words they understand and in a format that they want?

On the receiver side, if the message is complex, they don’t understand it. The reader, listener, viewer immediately wants to know “what’s in it for them.” If there isn’t that connection, then they shut down. This may even include the words the sender has chosen to use in their message (i.e., how many of you non-industry friends know what LFTR or LWR or IMSR stands for?). If they don’t understand the message or it’s too complex, they most often simply reject it. If we aren’t speaking their language, and presenting ourselves in a way that makes “sense and cents” to the audience, they simply aren’t interested.

How we can change

We have to connect our good news stories into the current zeitgeist, and that’s going to mean some strange bedfellows. The documentary Pandora’s Promise really kicked off one of those new strange partnerships linking environmentalists with the nuclear industry. Now before the comment field explodes, I’m not advocating the film, climate change, global warming, or anything else that seems to really upset people in the nuclear industry.

What I am saying though is, this film opened the eyes of a lot of people who have historically been against the nuclear industry. We’ve done nothing to follow up on that opportunity.

How can we be better?

  1. Acknowledge we have a problem—I think intuitively we all know that there are issues connecting all the positive aspects of nuclear with the general public. They believe the myths about the industry much more readily than the truth.
  2. Make a change—We don’t have to continue to communicate the way we always have. We need a new style, message, and method to make the impact that we all want to continue to move nuclear forward in the United States and Canada and not just something the rest of the world is doing.
  3. Review—When we do make a change, we are not going to get it perfect the first time. We’ll experiment and review how our messages have done informing, engaging, and entertaining the audience.

I welcome your comments and feedback and I hope we all work together to change how we communicate about the nuclear industry.

Seven Decades Past, A New Dawn

by Will Davis

Shortly before midnight on September 26, 1944, a sustained chain reaction was begun for the first time in a nuclear reactor whose purpose was not merely to prove that fission could be achieved or sustained. The brand new reactor at Hanford Engineer Works, Washington state, had only been complete for about a month; its first uranium fuel had begun loading only on September 13. Incredibly, this facility, of a nature that had never been attempted before (as man had only been aware of fission, itself, for less than a decade) was built in the incredible time span of 11 months; ground had been broken to build the reactor building in October 1943.

 

Construction begins on the Hanford 105B building -- the "B Reactor," first ever built.  The contractor was E.I. duPont de Nemours, usually just known as "DuPont."

With building construction nearly complete, workers have begun constructing the giant graphite moderator.  Thousands of bricks, eventually totalling 2200 tons, will be installed to slow neutrons to the energies required to interact with uranium fuel.

The completed 105B Building, otherwise known as B Reactor, the world’s first full scale non-experimental nuclear reactor.

The purpose of this reactor was fairly simple; it used a large number of uranium fuel elements that, under bombardment by neutrons from the chain reaction, produced plutonium. This plutonium could be extracted from the fuel through a chemical separation process, also performed at the vast Hanford site, and then concentrated to make atomic weapons. That was, in fact the purpose of this facility—under the purview of the Manhattan Project. The reactor developed a great deal of heat during this process (the original design as built was rated at about 240 megawatts thermal or MWt, but the reactor was substantially upgraded over the years to develop 10 times this) and it was of course natural to expect that this heat could be harnessed for power. At Hanford, the waste heat was simply dumped to the river, but the first nuclear electric generating stations in England and in France were of essentially this type—reactors whose primary purpose was to produce weapons material, but whose waste heat was harnessed to produce useful energy.

Of course, the reactor did not exist in a vacuum; not only were many various support facilities required (including a steam plant and pump house to provide 35,000 gallons of cooling water per minute for the reactor), but there were other reactors of identical type under construction very soon, spread around the giant reservation along the Columbia River.

Today, B Reactor remains unique at the site. While a number of other reactors were built, operated, and eventually shut down (as was B on February 12, 1968, for the last time) over the intervening years, these have been “cocooned” or placed in storage. B Reactor on the other hand is preserved (although long since defueled and cleaned up) and is open for tours; the site has received numerous landmark awards (including from the American Nuclear Society) and is recognized today for the place it played in history in many ways.

It’s quite clear that when the sun rose on September 27, 1944, it did so on a world that had changed—a world that could never turn back. While the immediate result of this project was nuclear weapons, nuclear energy had already been considered (since 1939, in fact, by the US Navy) and both might be thought of as having been born the night before. As the world today pulls back from nuclear weaponry, it finds itself advancing in energy demand, with nuclear playing a role now even into developing countries in Africa as well as established and prosperous countries in the Middle East. The immensity of the achievements of September 1944 cannot be underestimated.

Nucleoelectrica Argentina S.A. announced in July that it had entered into a contract with China National Nuclear Corporation to build a Chinese–sourced version of the traditional Canadian CANDU reactor at its Atucha site. This 800-MWe plant will be the fourth at the site (already occupied by two Siemens pressurized heavy water reactor plants, and the just-begun CAREM Small Modular Reactor plant) and the nation’s fifth nuclear plant overall (adding in the CANDU plant at Embalse.) This new unit will be Argentina’s most powerful nuclear unit, topping Embalse by 200 MWe.

Just yesterday, Nucleoelectrica Argentina released a video (subtitled in English and Chinese) showing the location and construction of this new nuclear plant—a plant that not only marks a step forward for Argentina, but in the bigger picture a step forward for China’s desired goal of widely exporting nuclear power plants.

Atucha III’s construction is expected to last eight years, and is a joint project between Nucleoelectrica Argentina, China National Nuclear Corporation, and Industrial and Commercial Bank of China. Nucleoelectrica Argentina will act as both owner-operator and architect-engineer, with CNNC providing “technical support, services, equipment and instrumentation” as well as materials that will ultimately be fabricated into parts in Argentina. The reference plant for the Atucha III design is the Qinshan CANDU-6.

In March of this year, Nucleoelectrica Argentina proudly announced the 40th anniversary of Atucha I, which it describes as “the first nuclear electric generating plant in Latin America.” The company expects to build yet another, still unspecified large commercial unit at the same site in the future, according to World Nuclear Association.

Another Nuclear Design Approved by the NRC

• This week the GE-Hitachi ESBWR design received its Design Certification from the Nuclear Regulatory Commission.

• “Design Certification” is a step in the licensing process for new nuclear power plants that allows a basic design for a nuclear plant to simply be referenced in the actual licensing process for a site, theoretically speeding the process.

Earlier this week, the US Nuclear Regulatory Commission granted design certification to General Electric’s Economic Simplified Boiling Water Reactor nuclear plant design, ending a years-long effort by GE to get design certification (called a DCA) and potentially paving the way to further new nuclear builds in the United States.

Dr. Solomon Levy mentions in his book “50 Years in Nuclear Power: A Retrospective” (American Nuclear Society, 2007) that the SBWR or “Simplified Boiling Water Reactor,” the predecessor design to the just-certified ESBWR, was begun as a design effort in the 1980s along with several other advanced nuclear plant designs. At that time, design was beginning to shift to passive safety features—those that take effect without operator action, which are included in the new design.

American Nuclear Society Treasurer Margaret Harding was with GE in various capacities for many years, and is familiar with BWR series development; she served as Fuel Engineering Leader for the ESBWR project. “The SBWR was a fully natural circulation reactor (meaning there are no pumps to move water through the core), was simpler, and thus less expensive than the forced recirculation designs that came before it such as the BWR/6 and ABWR,” she said. “The SBWR design eventually evolved into the ESBWR, which is even more simplified and has a number of both passive and active safety features.”

Harding said that there was a major push to reduce equipment and piping overall, leading to the decision to use natural circulation (the tendency of hot water to rise over cold water), but this led to the design of a wider, flatter reactor core that will require a slightly higher uranium enrichment than forced circulation BWR reactors and that may be slightly less economical from a fuel consumption standpoint. “But because fuel is such a small percent of your operating costs, that disadvantage isn’t huge,” she added.

Natural circulation BWR plants aren’t new; the Elk River Reactor, built by Allis-Chalmers (originally ACF) for Rural Cooperative Power Association in Minnesota in the late 1950s, was a natural circulation boiling water power reactor. Early problems with recirculation piping in various makes of boiling water reactors were another factor that led to the determined effort over the years to either move the recirculation pumps inside the reactor vessel and eliminate external piping (GE BWR/6, various ASEA–ATOM BWRs and the Hitachi–GE HP-ABWR) or else eliminate them entirely as in the ESBWR.

Of course, ESBWR is fully a GEN III+ plant (light water reactor with advanced safety features) in every sense of the term, with both fully passive and active core cooling features, a core catcher, a new containment, and more. GE-Hitachi has combined proven features from operating experience with a half century of boiling water reactors with advanced features in this design, which also interestingly is near the high end of available outputs with an electrical rating of 1600 MWe gross. The plant is available with either an 1800 RPM turbine generator for utilities that provide 60 Hz power, or a 1500 RPM unit for those that provide 50 Hz.

As of now, only two projects in the United States that have specified the ESBWR are active—namely, DTE Energy’s plan for a new Fermi-3 unit, and Dominion’s plan for a new North Anna Unit 3. DTE submitted to the NRC for a Combined License Application (COL) in September 2008, while Dominion submitted its COL in November 2007. Neither project presently has a planned date of completion for NRC review/issuance of the COL, however. In the case of North Anna-3, much of the delay centers on the fact that while Dominion initially selected the ESBWR, it switched reactor designs from 2010 to 2013 to the Mitsubishi US–APWR and then reverted to the ESBWR.

What’s next? Well, the next design to be certified in the United States might well be the South Korean APR1400. While the review process for this design was thrown back to Korea Hydro & Nuclear Power in December 2013 and remains officially at the “pre-application” status, a recent announcement by Korea Electric Power Company Engineering & Construction (which designs and builds Korean nuclear plants) reveals a sweeping inter-corporate contract among the major players in the South Korean nuclear industry to restart the push for US NRC design certification with actual application made by the end of 2014.

GE-Hitachi's ESBWR displays a number of highly advanced features, including a new containment, passive core cooling, and a core catcher.
