2011 Young Professionals Congress – Coming Soon!

By Peter Caracappa

The 2011 Young Professionals Congress (YPC 2011) is coming, and the time to register is now! YPC 2011 is an embedded topical of the American Nuclear Society Winter Meeting in Washington, DC, October 30–November 3, 2011. YPC2011 is the fourth YPC, and the second to be held as an embedded topical in parallel with the ANS Winter Meeting.

The YPC is jointly organized by the Young Members Group of ANS and the North American Young Generation in Nuclear (NA-YGN) to provide a forum for young professionals from across the nuclear industry to come together to discuss the challenges facing the next generation of nuclear professionals. Within this venue, young professionals have the opportunity to develop nontechnical professional skills, network among their peers, and explore the roles and functions of industry organizations such as ANS and NA-YGN.

The YPC has a full program beginning on the Monday afternoon of the meeting. Some of the exciting sessions planned include:

  • The Hacker Within: Scientific Computing Tutorial—A special demonstration from the University of Wisconsin, which has developed a series of short courses to provide time-efficient introductions to essential programming languages and tools without trying to turn engineers into computer scientists.
  • The Front of the Room—Tools, techniques, and strategies for effective presentations.
  • The Power of Storytelling—A creative session on knowledge transfer, focusing on an introduction to critical listening and critical question asking skills.
  • Challenges Facing the Young Generation in Nuclear—An interactive session that will build upon the outcomes of each previous YPC to develop a detailed list of recommendations and actions to better meet the needs of young nuclear science and technology professionals and their employers. Session participants will develop recommendations through small-group, moderator-led discussions.
  • …and more!

Registration for the YPC is part of the registration for the ANS Winter meeting. Meeting registration is discounted for ANS members who have not yet reached the age of 36, or are less than five years into their career after graduation. Online registration, as well as full program information, can be found at the ANS website.

Welcome to the June 2011 ANS Conference!

By Eric Loewen

As President-Elect of the American Nuclear Society, I welcome my fellow ANS members and non-members to the 2011 June conference!

One of the great privileges of belonging to a professional society is the opportunity to transcend the limitations of your own place of work and rise above into the overarching global industry. Joining a professional society gives you the opportunity to interact with fellow professionals at all levels and in all disciplines all around the world, which is precisely what we will be doing in Florida over the coming days. In the aftermath of a globally known event like Fukushima-Daiichi, this coming-together of leading nuclear scientists and engineers takes on an added importance due to the tremendous public need for accurate and credible information about nuclear science and technology.

As a nuclear engineer, I was greatly bothered by how the media barely mentioned the many other horrors experienced by survivors of the quake and the resulting tsunami. The Japanese Police Agency has confirmed more than 15,000 deaths and over 9,000 people missing, mostly from drowning, as the tsunami swept away entire villages. Yet, despite the great human toll wreaked by the tsunami and earthquake, TV, radio and newspaper coverage keyed on Fukushima Daiichi. TV reports espoused the ills of nuclear power with the background showing a massive oil refinery fire. Where was the media blitz—or even a mention—of the pollution from those refinery fires containing products that have no half-lives?

Since the events at Fukushima unfolded, ANS has been very proactive in addressing a tremendous number of public and media inquiries. Many of you have worked tirelessly to provide accurate and informed perspectives on the Fukushima incidents to your communities—and we thank you for your efforts.  ANS’ cooperative efforts with other nuclear organizations demonstrate how the nuclear community comes together to share information, lend expertise, and provide a helping hand to our nuclear brothers and sisters in Japan.

The Japan Relief Fund, which was established by ANS in mid-March, embodies that same strong community spirit. Contributions have exceeded $150,000, and the funds have been designated to assist employees and the families of employees at the Fukushima Daiichi, Fukushima Daini, and Onagawa nuclear plants, all located on the damaged east coast of Japan. Contributions, which are tax deductible, are still being accepted at the ANS homepage.

To further the nuclear knowledge base, ANS has established the Special Committee on Fukushima. We are very fortunate to have the leadership of Michael Corradini, chair of the Department of Engineering Physics at the University of Wisconsin, and Dale Klein, former chair of the U.S. Nuclear Regulatory Commission, in serving as committee co-chairs. During this June meeting, special sessions will be held on Monday and Tuesday, June 27 and 28, to discuss in detail the events at Fukushima. I urge you to attend these timely sessions.

As our knowledge and understanding of the events at Fukushima continues to grow, we must double our efforts to translate technical concepts into understandable terms and to counter those who would sow the seeds of Fear, Uncertainty, and Doubt (FUD) among concerned audiences. Providing clear, correct, and positive information about nuclear science and technology is the responsibility of each ANS member. While you are here in Hollywood, Fla., I encourage you to

  • Attend the Special Sessions on Fukushima and learn about what did and what did not happen. You are the nuclear expert to your friends and families—share what you learn with them.
  • Explore the public information and communications sessions at the meeting. Always take advantage of communications training! The tips and techniques you learn are useful in classrooms and boardrooms as well as media stages.
  • Go to the Social Media Gathering on Tuesday evening to learn more about how nuclear professionals are using new communications methods to share clear, correct, and positive information about nuclear. Follow up by stopping by the Public Communications Workshop on Wednesday evening, and join the discussion about how to be effective when sharing those messages with Capitol Hill.

As ANS members, we are best positioned to share our informed perspective and communicate the value of nuclear in our communities. I look forward to seeing you in Hollywood and hearing your ideas on how we can move forward together, as a nuclear society.

Nuclear professionals share facts about safety and aging

By Rod Adams

Some of us are old enough to remember when, in the 1970s, the US News and World Reports annual survey of careers with room for growth placed nuclear energy at or near the top of the list for several years in a row. I was in high school at the time, and had already decided that I was interested in energy production, nuclear in particular. The annual list publication reinforced my decision. My high school career lasted from 1973 to 1977, a period that coincided not only with the apogee of the first Nuclear Age, but that also was sandwiched between two significant oil-price-related recessions.

That era of optimism had come to a near standstill by 1986, the first time I could consider entering the civilian work force. Though there were many contributing factors, one influence that deflated the optimism was the repetitive media portrayal of the industry as risky, inept, and expensive. From the point of view available to most Americans (and we had little access to international news sources at the time), nuclear energy looked like an industry collapsing after an extended bubble.

That was a time in our history when information sources were far more limited and much more controlled. There was only a limited capability for people who knew more about technical reality than professional journalists to engage, respond, and debate. Even though there is still a mismatch between the reach of money-amplified speech and knowledge-based speech, the situation is slowly improving, but there are still major challenges.

Unless you have been too busy working this week to visit your favorite online news aggregation site, pick up a newspaper, or watch television, you will know that the Associated Press has released the first two installments of a planned four-part series about the nuclear industry.

The wire service invested more than a year’s worth of research into the effort, which must have involved a considerable expense. As a former businessman who understands a little bit about how the news business makes money, I am confident that the wire service’s goal from making such an investment included releasing sensational stories that attract a wide audience—that is the best way to obtain a substantial financial return on investment (ROI).

Surprise, surprise. When the first report was released, it weaved an impressionistic tapestry of the industry out of raw Nuclear Regulatory Commission event reports, input from disgruntled former nuclear industry employees, and quotes from professional antinuclear celebrities in an attempt to show that the big bad nuclear industry had developed an excessively cozy relationship with a compliant regulator.

According to the portrayal by the AP reporter, that alliance had conspired to reduce safety standards in order to allow nuclear plants to continue operating past their initial 40-year license period. That was not even the most inaccurate part of the picture—according to the AP reporter and the people he chose to quote as experts, the initial designers, builders, and regulators expected that the plants would have been replaced by the end of their “designed” 40-year lifetimes.

In the 1970s and 1980s, there was no established way for nuclear professionals to respond to such a slanted story. There is now, however, a growing network of writers that happens to also have nuclear training and its own established voice. Some members of that network frequently communicate with other nuclear professionals with a broad range of technical expertise on a mailing list hosted by the American Nuclear Society (ANS). That established “social media” network of people who know and trust each other swung into action.

One of the members of the group, Dr. John Bickel, has deep experience in the issues associated with aging nuclear plants. He shared a letter that he had written to the AP, calling them out for a misinformed report that ignored a number of key facts.

Within minutes of sharing his lengthy letter, Dr. Bickel received several offers from experienced bloggers to work together to produce a response article. As the bloggers realized, there was little chance of a long letter to the editor actually appearing in the press. Even if a shortened version did make it through the screening process, there would also be enough of a time delay to allow the story to experience the amplification of positive feedback to become a deafening screech.

Dan Yurman, who produces the well-respected Idaho Samizdat, got together with Dr. Bickel for a detailed interview. The product of that effort, titled Associated Press Nukes the NRC on Reactor Safety, was published on June 20, 2011, the same day that the AP report was released in the advertiser-supported media. Of course, coming from a wire service that has a world-wide reach, the AP report had a significant head start, but by day two, it no longer stood alone.

In addition to Dan’s response, the Nuclear Energy Institute produced a formal press release, a communication to its members, and a post on the NEI Nuclear Notes blog titled The AP Trawls for Nuclear Wickedness.

Now comes the hard part. These technically accurate, well-written responses need some amplification to give them a chance at competing with the reach of a wire service. We need the help of that often silent majority of people that support nuclear energy development to get involved and to use available tools (Facebook, Twitter, their own blogs, other social networks) to share better information. It would help the effort to add links back to Dan Yurman’s piece.

The second installment of the AP report pulled together incidents that have occurred over several decades to try to paint a picture of an industry that is plagued by leaking pipes, most of which carry water that contains incredibly tiny quantities of tritium. I took on that article with an Atomic Insights piece titled Buried pipes versus buried pipelines – hype versus hazard that quoted the findings of a year-long U.S. Government Accountability Office report titled NUCLEAR REGULATORY COMMISSION: Oversight of Underground Piping Systems Commensurate with Risk, but Proactive Measures Could Help Address Future Leaks.

What GAO Found

While experts in our public health discussion group generally agreed that radioactive leaks at the three nuclear power plants in our case studies of actual events had no discernible impact on the public’s health, these experts noted that additional information could enhance the identification of the leaks and the characterization of their impacts. The experts in our environmental impact discussion group concluded that environmental resources beyond the plant site have not been impacted discernibly(emphasis added)

There are two more planned AP releases. There is no reason to expect that the AP will praise the industry’s exceptional record of 10 years in a row of capacity factors that have hovered at 90 percent, its incredibly cost effective power that has a marginal cost of about 2 cents per kilowatt hour, or the fact that the operating plants produce virtually zero pollution of any kind. As ANS members gather in sunny South Florida, I hope they talk about real efforts to take advantage of our technical skills to spread the truth and work to overcome the well-marketed hype.

Thoughts on a Chart

By Meredith Angwin

Vermont’s Department of Public Service (DPS) is holding local meetings about a proposed Vermont Comprehensive Energy Plan, which is supposed to be on the governor’s desk in October.

On June 7, I went to the DPS meeting in Springfield, Vt. Three of us from the Hartford Energy Commission carpooled down and listened to a very good presentation by the new commissioner, Elizabeth Miller. Ms. Miller was appointed by Governor Peter Shumlin, a man who is a fervent opponent of the Vermont Yankee nuclear power plant. I was pleased to see, however, that Ms. Miller is thoughtful and articulate. I liked her presentation on Vermont’s Energy Future. (Note: the Web site for the Comprehensive Energy Plan is very good, but does not yet include the June 7 presentations.)

Why did I like her presentation so much? One reason is that she used the same chart I use in many of my talks about Vermont Yankee. The chart is from a presentation given by Dave Lamont of the DPS in March of this year.

The chart shows Committed Electric Resources—that is, contracts signed between Vermont’s utilities and electricity generators. The chart tracks 10 years (not a very long time, actually), starting in 2010 and ending in 2020. Here it is:

Click to enlarge

The chart assumes that Vermont Yankee closes in March 2012. You can see all the empty space (electricity demand) not filled with electricity contracts, starting in 2012.

Thoughts on the chart

The chart is quite dramatic. Vermont Yankee’s contribution goes down to zero by 2013, and the existing Hydro-Québec (HQ) contracts go to zero by 2016. There are new, widely-celebrated HQ contracts, but they do not fill in as much as what was provided under the old HQ contracts. (HQ is selling us less power in the future.) Granted, the chart does not include 60 MW from Seabrook, recently announced.

On the other hand, you may note that wind energy—providing almost nothing right now (light-blue near the top)—is supposed to be a significant contributor to Vermont by 2016. Indeed, Vermont utilities have announced purchases of wind power from New Hampshire and Vermont, and these “committed resources” are on the chart. The problem, however, is that the actual wind turbines are not on the ridgelines yet. People are fighting them tooth and nail for various reasons. So, I don’t think that wind will provide much power to Vermont very quickly.

Thoughts on the meeting

I was at the June 7 meeting with two of my fellow Energy commissioners. These people are devoted to energy savings, and they know quite a lot about houses, street lights (we’re all very proud of our street light project), and so forth. As typical Vermont Democrats, however, they are against Vermont Yankee (and they do not read my blog). One of them said that he had never seen the chart before, and he was surprised by it. My fellow commissioners are devoted and hardworking in their roles on the town’s Energy Commission, but they are also devoted to Vermont Yankee closing.

From my point of view, this chart is all over the place:

Also, I show the chart at Rotary presentations, and the DPS commissioner shows the chart at planning meetings. Yet, at least one of my fellow commissioners had never seen it before.

Thoughts on Ms. Merkel and Miss Marple

Merkel

When I get discouraged, I sometimes look at the Big Picture. In this case, it doesn’t help. I look at Germany, and at Prime Minister Merkel saying that Germany will have to build more coal plants to help with the “transition” from nuclear to renewables. These coal plants are likely to stay around awhile, I think.

Then I thought of Miss Marple, Agatha Christie’s senior-citizen detective. Miss Marple understands the world because, after all, “everything happens in a village,” she said. The motivations are the same in the microcosm of a village and in the larger world. In other words, the people of Vermont have a chart of future electricity sources, yet many people are ignoring it (despite my best efforts). The people of Germany will build coal plants—they aren’t ignoring their chart, perhaps. But they are deluded if they think that a coal plant won’t run for at least 20 to 40 years, once built. Those plants will not quietly fade away in 10 years in honor of wind turbines. As Miss Marple says, everything happens in a village. In this case, everything happens in Vermont. But with any luck, we will keep our nuclear plant, and Vermont will show the big world (including Germany) that nuclear, not fossil, is the proper bridge to a renewable future.

Small Modular Reactors and Current Policy Initiatives—Part 2

by Jim Hopf

Continued from Monday, June 20

Legislative Initiatives

Two bills concerning small modular reactors (SMRs) have been introduced recently in the Senate Energy and Natural Resources Committee.

Colvin

The first bill, S. 512, instructs the Department of Energy (along with private partners) to develop two standardized SMR designs. The intent is to obtain final Nuclear Regulatory Commission certification of the two designs by 2018, and to have an NRC construction and operating license (COL) for two actual plants by 2021. ANS president Joe Colvin testified before the committee in support of the bill.

The other bill, S. 1067, provides $250 million in funding over the next five years for research and development on how to reduce fabrication and construction costs for SMRs.

Perspective on SMR Legislation

R&D toward reducing construction costs for SMRs (or nuclear plants in general) could be very productive, with up-front capital cost being the most significant impediment to the growth of nuclear power. Thus, S. 1067 should be beneficial, the only question being how much. My personal view is that it doesn’t go far enough.

Current policies provide financial incentives (such as tax credits and loan guarantees) to utilities to build and operate new nuclear plants. The main reason, however, for the recent escalation in new nuclear plant cost is the lack of a sufficient supply chain for large and/or nuclear-grade components.  Therefore, it is possible that financial incentives to develop the supply chain would be an even more strategic investment than direct plant construction incentives, with respect to getting new nuclear deployed. How about tax credits or loan guarantees for fabrication plants and/or assembly lines to build whole reactors (in the case of SMRs) or large plant components (in the case of large reactors)? This should result in a significant drop in nuclear plant construction costs, which could make direct utility construction incentives unnecessary, at least over the longer term.

As for S. 512, some believe that the choice of (only) two standard designs to promote will stifle competition and innovation. There’s probably some truth to that. For me, the bigger issue is the schedule (i.e., a COL by 2021). This seems to be rather slow. In fact, it appears that industry may achieve a shorter schedule all on its own, without any government support at all.

For the two SMR designs that are simply scaled-down light-water reactors (i.e., NuScale and mPower), I believe that the companies in question are planning to file COL applications in the near future. I certainly hope that the COL application will not take about 9 years! My understanding is that the (private) companies’ timelines corresponded to having the first modules actually in operation by about 2020. The Tennessee Valley Authority, which plans to deploy (mPower) SMR(s) at one of its existing nuclear sites, is planning on forgoing the COL process, and opting for the old reactor licensing process, so it they can get started on SMR construction even earlier. If the government is (supposedly) helping, why is its timeline (i.e., merely having a reactor licensed by 2021) even longer?

A Real SMR/Nuclear Wish List

To really help SMRs, what the congress needs to do is reduce the regulatory red tape involved with bringing each SMR module (or any reactor) on line.

As discussed yesterday, SMRs may not make economic sense if the financial burden associated with security and emergency planning is no smaller than it is for large reactors. The much smaller potential release from these reactors should be considered when determining such requirements. At a minimum, SMRs deployed at existing plant sites should be able to just make use of the existing emergency plans, and be able to mostly just make use of existing site security. If the NRC does not take the initiative here, legislation may have to be an option.

Dry cask storage system

Another (aggressive) approach would be to have an SMR licensing process similar to that used for used fuel dry storage casks. With casks, once the NRC grants a license for a specific cask design, they can be fabricated and deployed from that point forward, without having to obtain any kind of license for each individual unit. (The NRC can and does have inspectors overseeing cask construction, but further license applications are not required.) Casks of a given design can even be deployed at different sites without additional licensing action. The only requirement is that the utility document all important site-specific parameters (such as maximum seismic accelerations) and show that they are bounded by the design’s generic licensing analyses.

I see no reason why a similar approach could not be used for SMRs. Such a change would be significant, because having to go through an NRC licensing process for each individual reactor module may add substantially to the overall cost of the unit, given its small size. At a minimum, a utility should be able to get a license to deploy a specific SMR design at a specific site, and then be able to add units without further license applications.

For nuclear in general, I think an effort should be made to reign in the cost and time associated with NRC licensing, particularly for follow-on COL applications for an already-licensed reactor design. A telling example of how onerous things are at present is the fact that one of the main legislative issues in Missouri this year was on the question of whether the utility should be able to charge customers in advance for just the cost of licensing (not building!) a new nuclear plant in the state. Even though this plant will merely be a copy of a licensed reactor (Calvert Cliffs would be the lead application for the design in question), the licensing process is expected to take several years and cost on the order of a hundred million dollars; a burden so great that it requires the attention of the state legislature. The NRC simply must do better than this.

I personally think that a COL application for a copy of an existing design (which supposedly is mainly about site characterization issues) should take no more than two years, and not cost anything close to $100 million. I also think that this is something that legislation can, and should, require.

Small Modular Reactors and Current Policy Initiatives

by Jim Hopf

Over the past year or so, there has been a lot of buzz about small modular reactors (SMRs). These are reactors whose electrical output ranges anywhere from ~25 MW to ~300 MW, as compared with over 1000 MW for large “conventional” nuclear power plants. With SMRs, the entire reactor (or possibly the entire nuclear island—NSSS) could be built in a factory and shipped to the site. Any site construction would be much more limited, and would only involve the (non-nuclear) balance of plant. Descriptions of some proposed SMRs can be found herehere and here.

Advantages of SMRs

Whereas SMRs start off with an apparent disadvantage due to lack of economy of scale, it is hoped that with volume production, assembly-line-produced reactors could wind up being cheaper than site-constructed large reactors. Performing the fabrication of the reactor and all other nuclear safety related components at a single, dedicated factory site may also result in a higher level of quality control and minimize construction defects.

In addition to the raw cost, SMRs may have less difficulty in obtaining financing than large reactors, and may enjoy lower financing costs (interest rates). This is due to several factors. The cost of each reactor would be much smaller compared with the overall financial assets of the utility, which lowers the risk of default. The construction period (i.e., the delay between borrowing the money and the generation of cash flow) would be significantly shorter for an SMR. In fact, down the road it may even be possible (particularly for the smaller SMRs) that the factory would have an inventory of reactors, allowing a reactor to be simply ordered and put into place. Finally, there would be a much lower risk of construction delays with an SMR, due to the very limited amount of on-site construction.

In addition to the economic benefits, SMRs may allow nuclear to be used in places where it otherwise wouldn’t. This would include in remote locations that don’t have enough demand for a large reactor, by utilities that are not large enough to take on a large reactor, or in regions where electricity demand is growing very slowly and large increments of new generation are not needed.

Potential SMR Drawbacks

Hyperion Power's SMR (Graphic: Hyperion Power)

Many of the potential drawbacks of SMRs revolve around the economy of scale issue mentioned earlier. In addition to the question of whether small reactors can achieve the same per-kW construction cost as large reactors, some requirements for running a nuclear plant, such as having sufficient in-house engineering expertise, plant site security, and emergency planning procedures, do not necessarily (or obviously) scale down with plant size. One of the main questions on the table is the extent to which the Nuclear Regulatory Commission will consider the fact that the potential source term (radioactivity release) from an SMR is much smaller than that of a large reactor, when determining the requirements for things like security and emergency planning.

Some of the above drawbacks may be minimized by deploying SMRs at existing reactor sites that already have security and emergency planning procedures in place. It’s not clear (in the continental United States, anyway) that there is any real need to increase the number of nuclear power sites, at least for now. That may also address the concerns, of some critics, that an increased number of nuclear sites would increase security risks. In any event, employing a large number of SMRs at a given site will certainly reduce these costs.

Continued in Part 2 on Tuesday, June 21, with perspectives on recently-introduced SMR legislation.

57th Carnival of Nuclear Energy Bloggers

Perhaps one of the more enduring cartoons that relates to the quality of information on the Internet is the one that states, “On the Internet no one knows you are a dog.” It shows a drawing of two dogs sitting in front of a computer terminal. Unfortunately, the cartoon is copyrighted material so it can’t be reposted here, but you can see it here along with many variations. The point of the cartoon is that words and images on the screen can come from anywhere and anyone.Clearing up misconceptions and outright falsehoods about nuclear energy since the March 11 Fukushima earthquake and tsunami is getting more attention these days. Problems range from not mainstream journalists not understanding the technical issues to people who are publicity crazed fear mongers out to get their face on a video.

For instance, during a telephone interview a reporter at a newspaper not to be named confused the plutonium content of mixed oxide fuel on Fukushima reactor #3 with weapons-grade plutonium ejected into the atmosphere from cold war atomic bomb testing.

In other instances, anti-nuclear groups have said that radiation levels in the water in Philadelphia are responsible for a spike in infant mortality. (FOX news TV report) These kinds of bogus news stories scare parents and the truth rarely catches up with fiction. Fox news has reportedly removed the video from its website, but, as is often the case with bogus content, it has gone viral and appears in numerous places on the Internet.

Is debunking nonsense likely to be successful?

Nuclear bloggers have been responding to these types of stories. For all their efforts, the more things evolve at Fukushima, the more nonsense appears on the Internet. Still, responding to it was the major preoccupation this week.

Yes Vermont Yankee

For starters, in her post Fuel Pools, Meredith Angwin at Yes Vermont Yankee quotes Arnie Gundersen predicting that fuel pools at Fukushima went critical. Actually, there were hydrogen explosions, but no nuclear explosions. Gundesen’s explanation of deflagration and detonation notwithstanding, hydrogen can and did explode. In other words, worrying that the fuel pools are about to become nuclear bombs is not a reasonable scenario.

Phronesisaical

Cheryl Rofer debunks a video (at her blog Phronesisaical) that has been flying around the Internet, claiming to show an explosion at a Fukushima fuel pool, when in fact it’s just steam and fog. She provides some reliable links with information about the Fort Calhoun, Nebraska, reactor that is withstanding Missouri River flooding ,and points out how Richard Bernstein has been begging the question of Iran’s intentions at the New York Review of Books.

NEI Nuclear Notes

Dave Bradish of the Nuclear Energy Institute takes on Grist’s anti-nuclear campaign. In Bradish’s last part of the three part series at NEI Nuclear Notes, he takes to town Grist’s bogus cost and insurance claims. For example, based on a study cited by Grist’s own author, Paul Gipe, the insurance cost for nuclear is lower than solar. If nuclear is “uninsurable” as the critics proclaim, then solar is catastrophic (at least if we go by their characterizations).

Atomic Power Review

In a blog post titled “How the Misinformation Superhighway Affects Nuclear Energy,” Will Davis writes at Atomic Power Review that the speed at which information travels on the Internet is exceeded only by the speed at which misinformation travels on it.For example, just a few days ago, a compressed video showing an hour’s worth of the Fukuichi Live Camera at the Fukushima Daiichi site, and which clearly shows a fog bank rolling in to the site, was widely circulated on anti-nuclear sites and deliberately mislabeled as having depicted some sort of explosion on the site

Davis attempts to obtain some focus on the position that the pro-nuclear crowd finds itself in, and the positions and hurdles it finds itself facing, in a blog-oriented not-yet-post-Fukushima world where anyone can write anything… but usually leaves a comment feature available.

Idaho Samizdat

At Idaho Samizdat, Dan Yurman posts his view on the conspiracy theories surrounding the flooding of the Missouri River near the Ft. Calhoun nuclear power plant. In addition to pointing out reasons, based on facts, why the plant is safe, he also notes the FAA “no fly” zone was set up primarily to keep news helicopters buzzing the plant at low altitudes from crashing into power lines or each other.


Atomic Insights

For those who think Germany’s retreat from nuclear energy will spark a revolution in renewables, think again, says Rod Adams.

Two articles that appear in the New York Times on June 15, 2011, should help to make it more clear to more thinking people—Russia, the world’s largest natural gas exporter, stands to gain the most money by an illogical, politically driven shift away from nuclear energy.

It baffles me why there is so much reluctance among even my friends and colleagues to accept my assertion that there is a relationship between that monetary gain and the strength of the antinuclear movement that is pushing the ill-considered policies.

Finally, here at ANS Nuclear Cafe, Ted Rockwell debunks myths about how radiation works and why and why not you may be harmed if exposed to it.

Jaczko – Will he stay or will he go?

Like the mascot in a famous advertising contest for the restaurant chain Bob’s Big Boy, NRC Chairman Gregory Jaczko has succeeded in raising questions of whether he’s to stay or go. The reason is his controversial management decisions.

At Next Big Future Brian Wang comments on an article at the National Review by Robert Zubrin calling for Jaczko to be fired. At the heart of the matter, Zubrin says, is the question of honest dealing in policy matters.

Far from being “fair and objective” in dealing with Yucca Mountain, in 2010 Jaczko issued a directive stopping an NRC staff evaluation of the project, precisely because the study would have shown that the project was sound. He then used the resulting lack of safety data as an excuse to order work on the Yucca Mountain project to be stopped altogether.

Breaking his promise to consult other members of the commission on Yucca Mountain matters, according to a report made public by NRC inspector general Hubert Bell last week, Jaczko “strategically withheld” information from the other commissioners and “was not forthcoming” about his intention to use his arbitrary directive to stop the project.

Will Jaczko be thrown under a bus by the White House? It’s not likely, says Margaret Harding, who writes at Four Factor Consulting that he is “untouchable” due to political air cover from Senate Majority Leader Harry Reid (D., Nev.)

The Inspector General of the NRC’s report has been leaked to various agencies and paints a portrait of a leader who is more concerned with his political calculus than leading the agency with which he is charged. Republicans in Congress have been incensed by his actions claiming he has “politicized” the process.

Congress can investigate him every which way they want, could even demonstrate that Dr. Jaczko has abused his position to further the agenda of his former bosses, Senator Reid and Congressman Markey. What they cannot do is to fire him from the position.

Beefing up nuclear safety

Gail Marcus, a former president of the American Nuclear Society, has some ideas at her blog Nuke Power Talk about beefing up nuclear safety regulation in Japan.

She points out that the IAEA preliminary report on the Fukushima nuclear crisis in Japan calls for independence for the Japan Nuclear Industrial Safety Agency (JNISA) which until now has been housed in the Trade Ministry. While it has long been apparent in the U.S. that you can’t promote and regulate an industry from the same government organization, Japan appears to be getting the news for the first time.

Marcus says that finding the right regulatory balance in an independent agency is just as important. She note that the reorganization of JNSIA is only the first step in a continuing process of regulatory evolution.

At Nuclear Green, Charles Barton writes that technology may provide some answers about safety in future reactor designs. Barton writes that although nuclear power is already the safest form of energy production, public fear of the release of radioactive materials, as evinced by the Fukushima reactor accidents, has led Germany and Italy to reject nuclear power.

While this response is irrational, safer reactors may be required to satisfy a fearful public. It is possible to build fluid fuel reactors that produce no plutonium, and to extract volatile fission product from their cores. Coupled with underground reactor placement, an extremely high level of nuclear safety is possible.

Some good news for a change

Brian Wang at Next Big Future does not disappoint with two posts that show that a sound mind and a self-assured approach to analysis can lead to good things all around.The Economist Intelligence Unit (EIU) sees a decade of growth for nuclear power, with only a marginal impact from the Fukushima accident. The EIU reduced its expectations for global nuclear capacity in 2020, but the figure still grows by 27 percent compared with 2010.

Also, Wang writes that he made a series of three bets with Michael Dittmar at the Oil Drum, who had four papers in Arxiv and had a bunch of coverage at the Technology Review, Economist, and newspapers. He predicted a failure to mine more uranium per year and a reduction in nuclear power generation from lack of sufficient uranium.

1. World Uranium production (official win for 2010)
2. World Nuclear power generation bets going to 2018 (official win for 2010)
3. Uranium production in Kazakhstan (official win for 2010)

Wang won the bets

Europe’s retreat from nuclear has unintended consequences

Rick Maltese writes at his blog on nuclear deregulation that the growing list of “cop out” countries like Germany, Italy, Switzerland, and maybe now Japan to increase their renewable energy supply and decrease nuclear energy calls for some honest assessment of the energy situation.

He notes that Japan’s Fukushima events affected Switzerland, Germany, and Italy to the point that they are likely going to need to sacrifice valuable land for wind and solar energy if they stick to their plan of going with so-called “renewable” energy.

A bright star on the horizon

Steve Aplin at Canadian Energy Issues writes that nothing is more exciting and inspiring than working with bright, motivated people in solving the great problems of our time.

Aplin reports on his daily interactions with people in the fields of chemical and nuclear engineering—two fields that, combined, will create the new energy of North America and the world.

Social media and nuclear energy

It’s not the same as selling donuts, cars, or promoting sports entertainment

By Dan Yurman

EBR-1 chalkboard ~ the 1st known nuclear energy blog post 12/21/51 on the Arco desert of eastern Idaho

As blogger on nuclear energy for the past five years, I realize I’m writing on a niche subject that isn’t going to pull in millions of readers. Unlike some entertainment blogs, a site on nuclear energy is never going to be able to link the words “reactor pressure vessel” with the antics of a Hollywood celebrity at a New York night club. So, what can be said about the use of social media and how it has evolved as a new communication tool in a mature industry?

Evidence of acceptance of social media is widespread, with the most recent example being the launch of the Nuclear Information Center, a social media presence by Duke Energy (NYSE:DUK). Content written for the Nuclear Information Center by a team of the utility’s employees is clearly designed to reach out to the general public. This effort goes beyond the usual scope of a utility Web site, which includes things like how to pay your bill online, where to call when the lights go out, and so forth.

The Nuclear Information Center announces right at the top that “In this online space, you will find educational information on the nuclear industry and the nuclear stations operated by Duke Energy. We will feature insights into radiation, new nuclear, emergency planning and more . . . allowing readers to get an inside view of the industry.”

That’s a big step for a nuclear utility. The reason is that like many publicly traded electric utilities, it generates electricity from several fuel sources, including coal, natural gas, solar, wind, and nuclear. Because these utilities have huge customer rate bases and supply chains, they are inherently conservative about the information they publish on their Web sites. Also, there are significant legal and financial reasons why a utility might or might not put information out there for public consumption. Press releases receive scrutiny from the general counsel and chief financial officer for very important reasons having to do with regulatory oversight and shareholder value.

Different approaches to blog rolls

Blogging the nuclear fuel cycle has little in common with news about Hollywood celebrities

Duke’s Web site is a completely modern effort set up like a blog, with new entries on a frequent basis. On the right column, the site has a list of other places to get nuclear energy information, including the American Nuclear Society (ANS), the Nuclear Energy Institute (NEI), and the Nuclear Regulatory Commission (NRC).

While even the NRC now has a blog, going beyond information about its operations in terms of content may be a stretch for the same reasons that Duke is cautious about links on its site. It is probably too much to expect Duke, or any other nuclear utility, to list any of the nuclear energy blogs.

Most nuclear blogs have a “blog roll”which list other publishers of information on the nuclear energy field.  Areva has done this on its North American blog. Areva handles the issue of avoiding any appearance of endorsement by noting that the list with more than two dozen entries is one of “blogs we read.” Areva also has several years of experience reaching out to the nuclear blogger community with monthly conference calls.

The blog of the Nuclear Energy Institute, NEI Nuclear Notes,  lists a wide range of nuclear blogs including this one as well as the blogs published by independent analysts.

Who reads nuclear energy blogs?

So, who is reading nuclear blogs? On the ANS Social Media listserv, I asked this question recently and got some interesting results for the month of May 2011. Here’s a sample of the replies:

  • Michele Kearny, at the Nuclear Wire, a news service, reports for the month of May 18,812 page views. Michele’s blog is a fast-moving series of news links that keeps readers coming back for updates.
  • Will Davis, at Atomic Power Review, who has been publishing high quality, in-depth technical updates about Fukushima, reports 31,613 page views for the same month.
  • Rod Adams, who recently updated the template at his blog at Atomic Insights, reported his numbers in terms of absolute visitors. He cites Google Analytics as reporting 10,583 unique visitors for May. Rod emphasizes commentary and analysis across a wide range of nuclear subjects.
  • At my blog Idaho Samizdat, I can report 6,945 visitors and 24,938 page views for May 2011. The blog covers economic and political news about nuclear energy and nonproliferation issues.
  • At ANS Nuclear Cafe, this blog uses WordPress to track readers, reporting 24,476 page views for the same four-week period as the other blogs. During the height of the Fukushima crisis on a single day, March 14, 2011, the blog attained over 55,000 page views as people poured on to the Internet in search of information about the situation in Japan.

Taken together, the four blogs that reported monthly page views represent 100,000 visits to online information pages on nuclear energy or an effective rate of well over 1 million page views per year. These are real numbers and the data are just for a small sample of the more than two dozen blogs on nuclear energy that update at least once a week.

Another interesting set of statistics is who reads North American blogs overseas? It turns out that the international readership is concentrated in a small group of countries. They include, in alphabetical order for the same sample of blogs, the following countries:

  • Australia
  • Canada
  • France
  • Germany
  • India
  • Japan
  • United Kingdom

Who else invests in social media?

The importance of social media has been recognized for several years by investments in it by organizations such as the Idaho National Laboratory, Areva, and recruiter CoolHandNuke.

A huge group of more than 5,000 people interact on LinkedIn, moderated by nuclear industry consultant Ed Kee. It is called “Nuclear Power Next Generation” and is one of dozens of such groups related to nuclear energy on the professional networking site.

Facebook anyone?

Nuclear energy is not so widely represented on Facebook as on LinkedIn, despite its enormous popularity, and isn’t conducive to the kinds of technical dialogs that populate other nuclear social media sites. While the Facebook format is attractive to lifestyle information such as dating and the promotion of entertainment, sports, and consumer packaged goods, it doesn’t seem to work as well for business and engineering topics.

It turns out Facebook is a good way to offer a “soft sell” for recruitment purposes to drive traffic to nuclear energy organization recruitment pages. It can answer the questions of what’s it like to work for an organization and the attractive amenities of life in the employer’s home town. Videos and photos can help deliver these messages.

Everyone is on Twitter

On the other hand, Twitter, even with its limits of 140 characters, is enormously useful for the nuclear energy field. Twitter users who follow the output of nuclear bloggers number in the tens of thousands, and many nuclear energy organizations, including the major utilities such as Entergy, have invested in a Twitter account to have a presence on the service. The American Nuclear Society “tweets” under @ans_org and posts updates daily on the situation at Fukushima

Traditional media meets social media

The mainstream news media has taken notice of the use of social media in the nuclear industry by reading the nuclear blogs and also by following them on Twitter. Has it made a difference in how the media covers the industry? To some extent, there is evidence that the national dialog on Fukushima and the future of nuclear energy, as covered by the media, was better than if social media was not used by the nuclear industry.

Web sites maintained by NEI and the World Nuclear Organization had to make fast upgrades to their computer servers to handle millions of inquires from the media and the public and on a global scale. Getting out the facts of the situation to respond to these inquiries was facilitated by this online presence at an unprecedented scale.

Even so, newspapers often had anti-nuclear groups on speed dial early in the crisis and their voices reached an unsettled public with messages of fear, uncertainty, and doubt. In response, ANS used technical experts on its social media listserv to information media engagements, which reached millions of views on network television and major newspapers like the New York Times and Washington Post.

This useful mix of free form communication on the listserv and excellent outreach by Clark Communications, working for ANS, made a difference in getting the facts about Fukushima to an understandably anxious public.

Margaret Harding, a consulting nuclear engineer with deep experience with boiling water reactor fuels, was one of the people tapped by ANS to be a spokesperson for the society. She wrote to me in a personal e-mail that social media made a difference for her in many ways.

In summary, she said that it would have been impossible for her to fulfill this role without many hands helping her from various quarters at ANS.

She pointed out that the ANS Social Media listserv group “provided invaluable background information . . that helped me keep up-to-date and ready for the question from the next reporter.”

In fact, she said, she might not have even started down this road if the listserv hadn’t already proven itself as a source of information and expertise.

Another take on the news media’s shift into anti-nuclear skepticism following Fukushima comes from Andrea Jennetta, publisher of Fuel Cycle Week.  Writing in the March 17 issue, she said that this time the “bunker mentality” that has characterized communications in prior years by the nuclear industry gave way to something new.

But instead of rolling over, the nuclear community for once is mobilizing and fighting back. I am impressed at the efforts of various pronuclear activists, bloggers, advocates and professional organizations.

In the U.S., I have to commend the Nuclear Energy Institute and American Nuclear Society, as well as a dedicated band of individuals first connected by social media and now forever bonded like soldiers in war, for being proactive in offering up an antidote to the poison spewed by the mainstream media and the antinuclear lobbyists.”

Engineers need soft skills

Engineers aren’t always comfortable with the soft skills of dealing with the news media. Blogs and other forms of social media, however, are the medium of information exchange for the next generation of leadership in the nuclear industry.

For instance, North American Young Generation in Nuclear (NA-YGN) told a group of nuclear energy bloggers just last week that it recorded 80,000 hours of volunteer time for its members in the past 12 months, and of that number, 36,000 hours were related to public information outreach. NA-YGN has a formal program to train its 7,000 members in 90 chapters how to talk to the public and the news media.

Recruitment and retention of the next generation of nuclear energy leaders to participate in its future will require the industry to clearly demonstrate it has mastered and integrated these technologies into its operations. It appears from the use of social media in the response to Fukushima that the nuclear field is rising to the occasion.

How does radiation damage work?

By Ted Rockwell

A typical description of what happens when you’re “exposed to radiation” sounds scary—a gamma ray slams into a cell! Sounds like something you wouldn’t want to have happen very often.

But we are, in fact, exposed to natural radiation all the time, and about 1 percent of our body’s 100 million million cells are damaged by natural radiation and repaired every day. Any virginal, undamaged cells in our bodies don’t stay that way very long.

Radiation is the least of a cell’s problems, however. The process of metabolism—breathing in oxygen to digest our food—causes each cell to be damaged and repaired a million times a day.

Damage by a gamma ray is somewhat different than metabolic damage, but the nature of that difference is understood. Even after accounting for that difference, there is about a million times more damage from the metabolic process than from natural radiation.

A lethal amount of radiation does its job, not so much by directly damaging the cells, but by inhibiting the body’s defenses—its damage prevention, repair, and removal processes. But an important implication of this radiobiological phenomenon is that when an organism receives a small gamma dose—e.g., 1 mSv—its damage-control processes are stimulated, not only to repair or remove most of the radiation-damaged cells, but also to repair/remove the much greater number of cells that were altered by metabolism and other causes (including cancer metastases). This is the source of hormesis, the process whereby small amounts of a stressor—whether it is radiation, sunshine, exercise, heat, vaccination, or poison—actually cause beneficial effects.

There is a lot more that could be said about radiation damage. You are invited to contribute your thoughts and concerns on the subject.

But would you buy it from Richard Nixon?

by A. Priori

Any time I’m having trouble getting actual work done, I like to barge in on other people and make it harder for them to work too. That’s why I was over at Rerouted River National Laboratory the other day, hanging out in the office of somebody who insists that I refer to him as “Dr. N.” This used to be his way of keeping me from jeopardizing his job by writing about what he actually says, but now he’s also a big-time blogger, with scads of Twitter groupies who know him only as “Dr. N.” So now, if I were to point out that his real name is Barlow Culbertson and he never got a doctorate, it probably wouldn’t create a ripple in the blogosphere; he’s much too cool as “Dr. N” for his first-life persona to matter to anyone.

“Spent reactor fuel has an image problem,” he said. “When people hear that something is ‘spent,’ they associate that with ‘worthless.’ The once-through light-water reactor cycle leaves behind fissile plutonium and plenty of fertile uranium. We need to change the mindset, and get people to start calling it ‘used fuel.’”

Pres. Richard Nixon

“Be careful what you wish for,” I said, wincing. “Do you think that used cars don’t have an image problem? Aren’t you old enough to remember the slogan about whether you’d buy a used car from Richard Nixon?”

“Of course I’m not that old. I have a blog, which now makes me at least 30 years younger than you.”

“I suggest we leave that subject aside until we can get an independent third party to see which of us has more liver spots. Anyway, what you’re facing here is euphemism creep.”

“I’m facing a creep all right, and that might indeed be a euphemism.”

I sighed. This wasn’t going the way it should. I was supposed to be getting on his nerves, not vice versa. There’s nothing like a blog to bring out an otherwise placid individual’s inner lout.

“What I mean by that,” said I, “is that if something is offered as a euphemism for a term that is held in disregard, eventually the euphemism will come to be held in the same disregard. The literal meaning of ‘cheap’ is ‘doesn’t cost much,’ but the public came to define ‘cheap’ as ‘shoddy.’ Then some bright boy in the ad biz tried substituting ‘inexpensive’ for ‘cheap.’ It may have worked for a while, but pretty soon people snickered when they heard ‘inexpensive,’ because its regard was as low as ‘cheap’ and it also seemed deceptive and evasive. More recently, we’ve heard ‘affordable’ offered up as a replacement for ‘inexpensive.’ And so the cycle repeats.”

Not-actually-a-doctor N rubbed his chin. “Haven’t car dealers tried to change the image of used cars?”

“Yep, and it’s really a hoot. The luxury brands, in particular, came up with the terms ‘pre-owned’ and ‘pre-driven,’ making it seem like they provided you this wonderful service of having someone else own and drive the car for you. Even luxury car buyers can see through that.”

“So we probably shouldn’t call the fuel ‘pre-irradiated,’ I guess.”

“Doesn’t come off the tongue very well, does it? Relax, Barlow, I’ll solve this little problem for you.”

He cleared his throat. “For those of you listening to the podcast, I should point out that my guest comes up with odd little pet names for people, and they exist only to amuse him and have nothing to do with the person being addressed.”

“Whatever. Just sign this consulting contract and I’ll give you a new name for fuel-that-is-no-longer-new.”

“All right, if I’m putting taxpayer money at risk, this better be good.”

“It’s simple,” said I, tucking away the contract. “The fuel isn’t spent. The fuel isn’t used. The fuel has passed some time in the reactor, and has been transformed into something which, with a little further transformation, can become something much more worthwhile than a once-through energy source. This fuel is:   maturing.”

“Hmm. Why not just ‘mature’?”

“Because the light-water reactor only took it part of the way there.  There are some small modular reactor folks out there who claim they’ll be able to take fuel right out of an LWR and burn it, but I don’t think anyone should count on that yet.”

He nodded. “I like it. It has an air of poise and responsibility, but also of continuing improvement, like fine wine. ‘Maturing’ fuel it is.”

I stood up. “There’s a lot to be said for maturing. I myself keep doing it every day.” I leaned in close to the podcast microphone. “It probably helps that I don’t have a blog.”

A. Priori

A. Priori doesn’t have a blog. Once in a while, this blog has him. That’s the story of E. Michael Blake (a senior editor of ANS’s Nuclear News magazine who hides behind the A. Priori persona when being particularly curmudgeonly), and he’s epoxied to it.

56th Carnival of Nuclear Energy Bloggers

Fireworks ahead over Yucca Mountain

The 56th Carnival of Nuclear Energy Bloggers is up at NEI Nuclear Notes

There will be fireworks this week as the House Energy & Commerce Committee holds hearings about decisions made by NRC Chairman Gregory Jaczko regarding the Yucca Mountain Project. Several nuclear bloggers took notice.

This week there is continuing news from Fukushima, but there are also a diverse set of posts on nuclear energy topics. If you want to hear the voice of the nuclear renaissance, the Carnival of Nuclear Energy Blogs is where to find it. Contrary to what the anti-nuclear crowd would like you to believe, the wheels have not come off the renaissance.

Past editions have been hosted at Yes Vermont Yankee, Idaho Samizdat, ANS Nuclear Cafe, NuclearGreen, and CoolHandNuke, as well as several other popular nuclear energy blogs.

If you have a pro-nuclear energy blog, and would like to host an edition of the carnival, please contact Brian Wang at Next Big Future to get on the rotation. This is a great collaborative effort that deserves your support. Please post a Tweet, a Facebook entry, or a link on your Web site or blog to support the carnival.

Food Irradiation: A Global Perspective & Future Prospects

By Ronald Eustice

Radura symbol used for irradiated food in the United States

The use of food irradiation has expanded globally during the past decade and is gaining renewed momentum as a steadily increasing amount of irradiated food enters commercial channels in the United States and worldwide. Although irradiated fruits, vegetables, and poultry have been available commercially since the early 1990s, the introduction of irradiated ground beef by Huisken Meat Company in Minnesota during 2000 significantly increased awareness and interest in the technology.

Today, 15 million–18 million pounds of irradiated ground beef and poultry are marketed in the United States annually. Schwan’s and Omaha Steaks have chosen to irradiate 100 percent of their raw ground beef. Ground beef sales at Omaha Steaks have doubled. Wegman’s, a Rochester, N.Y.–based retailer with more than 80 stores in New York, Pennsylvania, Maryland, has offered fresh irradiated ground beef as a value-added product since 2000.

These highly respected food companies have made the decision to irradiate ground beef because of serious concerns about foodborne illness from E. coli and salmonella. The U.S. Centers for Disease Control and Prevention (CDC) estimate that each year roughly one out of six Americans (or 48 million people) become ill from food; 128,000 are hospitalized and 3000 die.

Tauxe

Robert Tauxe of the the CDC estimates that if 50 percent of poultry, ground beef, pork, and processed meats in the United States were irradiated, the potential benefit of the irradiation would be a 25-percent reduction in the morbidity and mortality rate caused by these infections. This estimated benefit is substantial, as irradiation could prevent nearly 900,000 cases of infection, 8500 hospitalizations, more than 6000 catastrophic illnesses, and 350 deaths each year in the United States.

Papaya

While the volume of irradiated meat and poultry sold is holding steady, the amount of irradiated produce is growing rapidly. Estimates are that in 2010 about 15,000 metric tons (35 million pounds) of irradiated fresh produce was consumed in the United States. This volume includes papaya, longans, lychees, and Okinawa sweet potatoes from Hawaii, mangoes, guavas and boniato sweet potatoes from the southeastern United States, mangoes from India and Mexico, guavas from Mexico, dragon fruit from Vietnam, and other items. Australia has become a leader in food irradiation and has seen exports of irradiated mangoes to New Zealand triple in the past three years.

It is estimated that one-third of commercial spices—about 175 million pounds—are irradiated and consumed in the United States. This volume will grow because of recent food safety concerns involving contaminated spices. Rapid worldwide growth is also occurring in the irradiation of pet treats and animal feed because of salmonella concerns.

While irradiation is being used to protect public health by eliminating harmful bacteria and to access new markets by destroying unwanted pests, there is a growing need to use irradiation as a tool to prevent food spoilage by extending shelf life of produce and other foods, especially in developing countries. With 30 percent–50 percent of the food we produce being wasted before it reaches the consumer, the time has come to use irradiation as a tool to extend shelf life and reduce world hunger. While food irradiation remains an underutilized technology, it is an important tool that will make our food safer, keep food fresh longer, prevent insect infestation, and eliminate phytosanitary concerns so that fruits and vegetables can be exported to global markets.

Eustice

Ronald Eustice has served since 1990 as executive director of the Minnesota Beef Council. Among his numerous important contributions to agriculture, food production, and public safety is the demonstration of the effectiveness of irradiation technology in eliminating the scourge of E. coli O157:H7 in meat and produce. He is a new contributor to the ANS Nuclear Cafe.
