Canada’s ZED-2 reactor defines the future of Candu designs

Blair Bromley visiting the ANS Media Office during the 2010 winter meeting in Las Vegas (11/09/10)

What is it that gets a Ph.D. reactor physicist up in the morning to do work associated with a 50-year-old research reactor located at the Atomic Energy of Canada Limited’s (AECL) Chalk River Laboratories?

With a worldwide shortage of trained nuclear engineers, Blair Bromley could potentially work in many other countries with growing nuclear power programs. What keeps him in Canada?

It turns out that Bromley likes the fact that with the availability of the ZED-2 low power research reactor, Chalk River is a “one-stop shop for nuclear R&D.”

Bromley stopped by the American Nuclear Society’s media office at the Winter Meeting in Las Vegas in early November to talk about what he calls “the workhorse of Canada’s nuclear reactor physics design program.”

He pointed out that “fundamental reactor physics R&D from ZED-2 has been used in almost every Candu reactor ever built.”

See the ANS Nuclear Cafe blog post: AECL research reactor gets landmark status

Running the numbers

ZED-2 Graphite came from England

The ZED-2 heavy water critical facility (a low power research reactor) is used to produce measurement data for the validation reactor physics computer codes that predict and explain how a reactor will behave during actual operations.

About 30 people work on three teams at the facility. The first team develops computer codes. The second designs and runs ZED-2 experiments, and the third works on validation of codes based on measurements from reactor measurements.

Bromley, who earned his doctorate in nuclear engineering from the University of Illinois, pointed out that a many critical experiments were performed in ZED-2 in support of AECL’s new reactor design – the ACR-1000 (Advanced Candu Reactor).

Looking down on ZED-2

“It is relatively easy to configure the ZED-2 reactor for a variety of experiments,” Bromley said. “The core is a modest size, with a reactor vessel of about 3.3 meters in diameter and height.”

What’s next for the ZED-2 reactor? Bromley ticked off a series of potential new tasks, which may include:

· Finishing up experiments in support of the ACR-1000.

· Additional experiments in support of traditional Candu reactors.

· Testing the physics of experimental thorium-based fuels.

· Testing the physics of Candu-type fuel bundles using simulated recycled light-water reactor fuel.

· Testing the physics of fuel lattices representative of those that might be used in a super-critical-water-cooled Candu reactor (Candu-SCWR).

Global future for Candu?

The worldwide installed base of Candu reactors includes 20 units in Canada, four in South Korea, two each in Romania, China, and India, and one each in Argentina and Pakistan. Since the early 1970s, India has adapted the Candu design for its domestic commercial heavy water reactor program.

“The basic design (the Enhanced Candu-6, EC6) is a 700-MWe unit that runs on natural uranium,” Bromley said.

The future of the Candu design may be defined by its ability to run on spent fuel from LWRs, which has just 0.95 wt%U-235/U.

“I expect heavy water reactors to have a more important role in the future by taking advantage of the energy potential available in spent fuel. As the world reactor base expands, for every four light water reactors, there could be one heavy water reactor utilizing the spent fuel,” Bromley said.

The attractiveness of the Candu design is that it has what is known as a “high neutron economy” and can run on natural uranium, thereby avoiding the need for enriched fuel and large uranium enrichment facilities.

Another advantage is uranium resource utilization.

“With heavy water reactors, you don’t waste neutrons and you save more to generate fission. You get more megawatt-days of energy per kilogram of uranium mined, as much as 30 percent or more compared to a PWR,” Bromley said.

As we closed the interview with Bromley, the wire services were clicking with news that the federal government in Canada was considering the privatization of AECL’s reactor business, while retaining ownership and control of the R&D wing of the government-owned crown corporation.

Bromley declined to comment on these developments. He said that he is hopeful that whatever the outcome may be, the world is going to realize the advantages of heavy water reactors, as embodied in Candu technology, and will start to incorporate it into new fleets of reactors. When that realization occurs, Bromley and his colleagues will be ready to provide the numbers and technical support to show the world how it works.

The View from Vermont

The push for books

By Meredith Angwin

The Ethan Allen Energy Education Project has been running for about two months now. The Project will address current issues, such as relicensing the Vermont Yankee nuclear power plant. For me, the Project’s official start was the kickoff meeting on September 30.

We held the meeting at a local site, the Montshire Museum of Science, in Norwich, Vt. About 20 people attended, and a video of the meeting is available here (at bottom of linked page). Information is also available at my own blog site, Yes Vermont Yankee.

There are many proponents of the Vermont Yankee plant. In October, at Castleton College in Vermont, VY supporter Howard Shaffer (who also writes columns for these View from Vermont posts) debated a man from Public Citizen, the Nader organization headquartered in Washington, DC. Three hundred students attended the event. There also were many smaller events last month, as I noted in my last blog post, the View OF Vermont.

As the holidays approach, I am working on coordinating our pro Vermont Yankee efforts with others, and expanding our scope in new ways.

O’Donnell

Coordination. Patty O’Donnell is a former state representative for the town of Vernon, where the Vermont Yankee plant is located. She didn’t run for office this time around, and instead has devoted herself to Vermont Yankee advocacy. O’Donnell recruited some Vermont Yankee employees to accompany her (on their own time) to attend community meetings to give talks about Vermont Yankee. I knew that O’Donnell (R., Vt.) was doing this, and she knew that I was giving presentations, but only recently did we get together to set up some coordination.

Shaffer

About a week ago, Howard and I sat with Patty in her living room, planning future events. I looked around and thought, “Howard is the ANS Vermont Pilot Project coordinator.  I am head of the Ethan Allen Institute Energy Education Project. Patty is a former legislator who knows the ropes around Vermont.”

(Click here to see Patty O Donnell’s pre-election Op-Ed piece about Vermont Yankee.) 

It felt good to have people to meet with, have brownies, and coordinate plans.  Just having the meeting was a goal achieved for me!

Expansion. The Energy Education Project is expanding its scope. A man who is a member of the Project e-mailed me, saying, “I would love to buy every member of the Vermont legislature a copy of Gwyneth Craven’s book, Power to Save the World.”

I took him up on his offer. Actually, I asked him instead to sponsor the expenses for Cravens to visit Vermont, and I said that I would be the one to raise additional funds to buy the books for the legislators. Gwyneth Cravens will visit Montpelier this January, and all the legislators will be given a copy of her book. We have checked, and legislators can receive books and printed matter in Vermont, without declaring them as “gifts.”

Caldicott

Cravens

Helen Caldicott has done a similar thing, visiting the legislature and doing a booksigning, sponsored by Vermont Yankee opponents. This year, we will have our own celebrity booksigning, featuring Cravens. It feels good to plan something like this for the Vermont Yankee advocates.  Something positive, not just reacting to mud that is thrown at us.

By the way, ’tis the season for giving, and we plan to give away quite a few books. Please consider going to the Energy Education Project Web site and supporting nuclear energy. Your gifts are completely tax-deductible, and there is a “Donate” button through PayPal. Help to buy books!

The success of putting this together has led me to having more ideas. Opponents of the plant are not a homogeneous bunch, all with the same views of nuclear. For example, I have met with one group in Brattleboro that wants to build a new, extra-safe accelerator-driven thorium reactor on the Vermont Yankee site.

Now, these accelerator-driven reactors are only in the design stage, but at least the Brattleboro people are pro-nuclear at some level.

I hope that I will be able hold a public meeting in Brattleboro about the different types of advanced nuclear plants, including the one that the opponents favor. The meeting would feature a guest speaker that the opponents would provide, talking about the accelerator-reactor, and a guest speaker that we would provide, talking about Gen IV reactors. This could lead to increased acceptance of all sorts of nuclear energy (although not necessarily Vermont Yankee). Every little bit of goodwill helps. I’ll keep you informed of my progress on this.

Happy holidays!

2011 ANS Special Award announced

Happy Thanksgiving! The topic for the American Nuclear Society’s Special Award in 2011 is “Innovations in Small Modular Reactors.”

The Special Award was established in 1962 by ANS to recognize individuals for meritorious contributions in research and/or developing understanding into the important areas of the selected topic. A different topic is chosen each year by the ANS Board of Directors based on recommendations from the society’s Honors and Awards Committee. Each topic is selected based on its importance to the peaceful applications of nuclear technology to mankind.

The award is intended to go to an individual, or individuals, rather than to a large group or institution. The candidate/s for the award should have played an outstanding role in the necessary research and analysis and/or in the interpretation and leadership associated with furthering the overall understanding of the topic. Nominees must be living, but need not be ANS members.

Nomination forms are available at the ANS Web site or from ANS Headquarters. Eight copies of the completed form and supporting materials must be received at ANS headquarters before April 1, 2011.

Plaques and a monetary award totaling $1000 will be presented to a winning individual or team at an ANS Annual Meeting in 2011.

Nuclear engineering, going forward

By Peter Caracappa

What does it mean to be a nuclear engineer? That question is not as
easy to answer as it once was.

Looking back on the field of nuclear engineering education in the past 20 years or so, some very interesting changes have taken place. In many ways, nuclear engineering is still a niche program. Compared with the “big boys” such as mechanical and electrical engineering (with hundreds of programs available), there are relatively few nuclear engineering programs – only about 30 – across the United States. Even at its height, there were no more than 50 programs. Many of them closed down as enrollments collapsed through the 1990s, and new programs have only very slowly begun to be added in recent years.

More importantly, there has been a shift in what it means to study nuclear engineering. What happened is that nuclear engineering began to take its  place – and I would say its rightful place – as one of the major fields of engineering.

Gas-cooled fast reactor schematic

The traditional view of nuclear engineering is the study of getting power from nuclear fission. There is plenty of interesting work to be done within this definition. With new reactors being built and Generation IV reactors being designed, there is a significant need for students in this area. But when nuclear engineering departments were struggling, many of them broadened their focus out of necessity more than anything else. They began to think of nuclear engineering as any application of nuclear and atomic interactions. Thinking of it this way, there are many more diverse applications in the field, such as homeland security, medical imaging, and plasma physics.

Considering the history of the different branches of engineering, they
all followed roughly the same pattern. They started out as a fairly
narrow field of study, and matured into a much more general and diverse
field. For example, when the first students began to study mechanical engineering, they all learned how to design steam engines and the things to do with them. Electrical engineering was largely the study of generators and motors. Chemical engineers worked mostly on the things that could be made from petroleum. Clearly, these fields are no longer thought of as narrowly as
that.

What will these departments do now that enrollments are increasing and new construction is beginning? Some may choose to return to traditional definitions of nuclear engineering – to be a niche program feeding the nuclear power industry. The broader applications of nuclear science and technology, however, are only going to become more important. If the idea persists that being a “nuclear engineer” is about more than just fission reactors, nuclear engineering programs may just be as common as mechanical or electrical engineering programs.

With a population of graduates well trained in the applications of atomic and nuclear physics – think of the possibilities!

AECL research reactor gets landmark status

The international nuclear community designated the Atomic Energy of Canada Limited’s (AECL) Zero Energy Deuterium 2 (ZED-2) research reactor a nuclear historical landmark, presented by the American Nuclear Society.  The award, given on November 2 during a technical conference in Ottawa, honored the reactor for its 50 years of operation and for its outstanding contributions to the global nuclear industry.

Chalk River Lab

Over the past five decades, ZED-2 has been involved in testing fuel designs for AECL’s Candu reactor series and testing advanced fuel cycles for future reactors. The reactor continues to serve this purpose. Its landmark status, officially declared in September this year but not awarded until the November meeting, is being marked by a bronze ANS Nuclear Historic Landmark plaque at AECL’s Chalk River Laboratories in Ontario, where the ZED-2 is located.

The award was presented to AECL by ANS President Joe  Colvin, during the Canadian Nuclear Society’s (CNS) Technical Meeting on Low-Power Critical Facilities and Small Reactors, where industry experts and academics gathered to showcase nuclear accomplishments.

The landmark status is given to sites or facilities where outstanding physical accomplishments have taken place that were instrumental to the advancement and implementation of nuclear technology and to the peaceful uses of nuclear energy.

Colvin

Colvin commented on the significance of the award. “The American Nuclear Society is pleased to present this Nuclear Historic Landmark Award to the ZED-2 Heavy Water Critical Facility in recognition of the valuable physics data it provided in heavy water reactors, an outstanding physical accomplishment instrumental in the development and implementation of nuclear technology and the peaceful uses of nuclear energy,” he said.

Benjamin Rouben, CNS executive administrator, added, “We have come from all over the world to mark the historic occasion of the 50th anniversary of ZED-2, and to articulate the important accomplishments that ZED-2 and similar facilities have made in scientific research.”

“This event is a true international celebration of the progress we’ve made in Canada through these nuclear facilities. The ANS award is recognition of this and Canadians should be proud of it,” Rouben said.

ANS certificate

Rick Didsbury, acting vice president and general manager of Research and Development at the Chalk River Laboratories, said, “Over the past 50 years, ZED-2 has proven to be a key facility in the advancement of nuclear science and technology for the benefit of people around the world. This prestigious ANS award is clear evidence of this.”

“This technical conference is an opportunity to celebrate the achievements of this important research facility, as we gather to foster global partnerships around nuclear research,” he said.

About ZED-2
Built in the late 1950s, the ZED-2 Critical Facility achieved first criticality on September 7, 1960, and turned 50 years old earlier this year. ZED-2 is the successor to ZEEP – the first nuclear reactor outside the United States – and was initially built to test the fuel arrangements of Canada’s first power plant.

Since that time, ZED-2 has supported the development of the Candu industry by testing a wide range of fuel bundle designs and fuel arrangements at low power (usually between 5 to 100 watts) under a variety of operating conditions and simulated accident scenarios.

ZED-2 continues to operate today, actively supporting improvements to the current fleet of Candu reactors and to the development of next-generation reactor concepts, including advanced fuel cycles and thorium fuels. ZED-2 is also used to calibrate neutron detectors for use in power reactors.

Federal Affairs brainstorming session: Communicating the benefits of nuclear energy

How to communicate the benefits of nuclear energy more effectively

During the American Nuclear Society’s Winter Meeting on November  7-11 in Las Vegas, Nev., the Society’s Public Information (PI) Committee sponsored a workshop titled “Focus on Communications: How ANS Members Can Carry the Nuclear Energy Message to the New Congress.” This always-popular workshop was hosted by Mimi Limbach, ANS PI Committee member and partner, Potomac Communications Group, and  Craig Piercy, ANS Washington representative and senior vice president of Federal Relations, Bose Public Affairs Group.

Using an interactive, open-microphone format, the workshop included a brainstorming session on how nuclear professionals can better
communicate the advantages and benefits of nuclear energy to the U.S.
Congress and to the public at large.

Here is the list of ideas offered by participants during the workshop:

Communications & Outreach Opportunities

  • Talk to your communities, ally with universities.
  • Don’t be dismissive of the critics – they have challenged us and we’ve become better.
  • Make nuclear energy more accessible to the public – develop a nuclear “Did you know?”’
  • Point out medical applications.
  • Sell the benefits of nuclear energy, don’t trash the competition.
  • Humanize the technology.
  • Social media is a powerful medium – use it! Viral videos, Facebook, Twitter, Linked In, etc.
  • Find a cute mascot.
  • Energy Education vans – bring them back.
  • Bust stereotypes.
  • Establish a positive message with a backbone.
  • Need to communicate best practices among ourselves – help others build on what ANS local chapters have accomplished.

Educational Outreach

  • Concentrate on education from kindergarten through college.
  • Tackle the inherently anti-nuclear textbooks.
  • Entergy integrates nuclear energy materials into state curriculum in partnership with Global Energy Solutions; NA-YGN is going to adopt nationwide.
  • Target teachers, pair with nuclear engineering faculty.
  • Educate current nuclear science & engineering students to be good communicators.
  • Investments in student sections & outreach yield high returns.

Environmental & Natural Resources Benefits of Nuclear Energy

  • Natural resources (gas, oil) are finite = depletion of resources.
  • Position nuclear  energy as inexhaustible.
  • Nuclear energy density is sexy!
  • Emphasize why nuclear energy is a solution to energy sprawl.
  • Build coalitions with local environmental organizations.
  • Solar is really nuclear.
  • Do not concede used nuclear fuel as waste; reposition the Yucca Moutain repository as the “Strategic Nuclear Fuel Reserve.”

Economic Competitiveness of Nuclear Energy

  • Use the French experience as a model – cost efficiency.
  • Invest in nuclear energy to address potential inflation – value for investment.
  • Utilities should provide percentage and cost of each generating source.
  • Energy costs affect our global competitiveness.
  • The issue is financing – Wall Street . Nuclear energy is the only industry that takes care of its waste cradle to grave. Wall St. doesn’t understand financing a 60-year project.

Government Role(s) in Nuclear Energy

  • Change NRC cost recovery formula for Small Modular Reactors.
  • Simplify export rules.
  • Provide more incentive for utilities to build new plants.
  • Public needs to know about importance of government role in energy policy.
  • Need to level the playing field, RE: subsidies, but be careful, it’s a double-edged sword.
  • Government funding has helped make advanced nuclear power plants economically competitive.
  • Convene a workshop with pro-nuclear state legislators to develop a model statute for” Construction Work In Progress” (which allows public utility commissions to give utilities permission to charge ratepayers for a portion of the cost of nuclear plant construction before the plant goes into operation). Take worksops on the road to public utility commissions for feedback. Pitch to Council of State Legislators for support.

Non-Proliferation & National Security

  • Swords into plowshares – we’re not making nuclear weapons, we’re destroying them!
  • 15 percent-18 percent of U.S. defense budget is spent to guard the Straits of Hormuz for energy transport – nuclear is a national energy security solution.

Safety

  • One of safest industries in the nation – more dangerous to work in an office building than a nuclear energy facility.

UAE Ambassador to IAEA pursues development of nuclear energy

Hamad Al Kaabi is a nuclear engineer

By Dan Yurman

In December 2009, the United Arab Emirates awarded a $20 billion contract to a consortium of South Korean firms to build four nuclear reactors on a remote desert location along the Persian Gulf. The consortium, led by state-owned Korea Electric Power Corp. (KEPCO), is committed to having the first reactor in revenue service by 2017. The change from fossil (natural gas) to uranium as a fuel source comes not a moment too soon as the UAE is now a net importer of gas for electricity generation and desalinization.

At the ANS Winter meeting, which took place in Las Vegas, Nev., on November 7-11, I had the opportunity to interview one of the key players in the UAE’s nuclear program. Ambassador Hamad Al Kaabi (right) is the UAE Permanent Representative to the International Atomic Energy Agency (IAEA) in Vienna. He has been personally involved in key milestones of the country’s nuclear energy assessment, including:

  • A national scope energy assessment evaluating future UAE requirements and potential sources of electricity.
  • Drafting and release of the policy of the UAE on the evaluation and potential development of nuclear energy.
  • National nuclear energy legislation.
  • Bilateral agreements related to cooperation in the peaceful uses of nuclear energy between the UAE and various nuclear supplier nations, including France, the United States, the United Kingdom, and the Republic of Korea.
  • The UAE pledge of $10 million to support an IAEA-administered international uranium fuel bank initiative, resulting from a proposal by the Nuclear Threat Initiative.

Ambassador Al Kaabi trained as a nuclear engineer, getting his bachelor’s and master’s degrees from Purdue University in Indiana in the United States. His graduate work focused on nuclear safety.

Background of UAE nuclear deal

In 2006, a UAE energy working group developed projections for electricity needs. It found that demand would expand by three times the current level of use by 2020. The question was how to meet demand.

The UAE evaluated all energy sources including oil, gas, renewables, and nuclear. The working group found that natural gas supplies are not sufficient for future needs. The UAE imports a growing portion of its natural gas supplies. The UAE cannot get more nor produce more since the gas supply is driven by oil production, which is under quota. (see table below)

In addition, the gas has a high sulfur content, which along with burning oil, yields poor environmental performance, and burning oil is a hit on revenues from oil exports. In a nutshell, increased emphasis on fossil fuels had the potential for increased environmental and financial costs that were not acceptable to the UAE.

New technology for desalinization

Desalinization will be supported by nuclear energy. Currently, the UAE is using natural gas to heat seawater and remove fresh water from the process. The UAE will use electricity from the new reactors to run a reverse osmosis plant. While the technology is complicated, recent innovations make it a feasible choice to use on a large scale.

Smaller reverse osmosis units can be placed closer to end users, e.g., factories and cities, thus reducing water pipeline and delivery costs.

“We can make water at night when electricity demand is low,” Al Kaabi said.

Solar not the answer to gas use

Despite abundant sunshine, Al Kaabi said that renewable energy sources are not the answer to the challenges of using fossil fuels.

“Even aggressive investment in renewable energy like solar will yield only a small amount of electricity to meet rapidly growing demand. It is not proven that solar can meet base load requirements,” Al Kaabi said.

He added that the UAE has had some problems with manufacturing issues regarding solar panels delivered to the UAE and problems with dust from the desert cutting down on the efficiency of solar cells.

Nuclear chosen for reliability and capacity to meet demand

Ultimately, nuclear energy was chosen for the energy path forward because it is a proven, reliable technology that is economically competitive.

The UAE set three broad principles for the path forward for nuclear energy:

  • Safety
  • Security
  • Nonproliferation

The UAE held early consultations with the IAEA to develop a “roadmap” for legislative, institutional, regulatory, and technical organizations. In setting up these organizations, the UAE reviewed best practices globally. Due to the urgency of energy issues, the UAE set 2017 as a target date for start of revenue service for the first reactor.

The next issue was site selection. The UAE chose an uninhabited coastal location on the Persian Gulf. The Braka site is about 50 km (31 miles) from the center of Abu Dhabi’s oil industry at Rawis. A port facility will be developed to receive reactor components and construction materials by sea.

The two most important organizations in the UAE new build are the Federal Authority for Nuclear Regulation (FANR), which has 100 employees, and the Emirates Nuclear Energy Corporation (ENEC), which has 300 employees. These employment numbers are expected to grow.

ENEC will manage the construction and operation of the reactors. It will handle all aspects of the supply chain. FANR will handle nuclear safety. A separate government ministry handles security for nuclear facilities.

Another organization is developing a program to educate and certify nuclear engineers in the UAE. The UAE will need them all by 2017.

Of the nation’s three million people in the labor force, more than 80 percent are expatriates. The UAE has a goal of educating its own citizens to run the nuclear plants. The reason is that the reactors offer high paying jobs with long-term stability.

Key factors in the contract award

In December 2009, UAE awarded a $20 billion contract to build four 1400 MW PWR type reactors to a consortium from South Korea. Key factors were a buildable design, procurement and construction of components, and lifetime operability. The tender process was completed in a record time of one year.

Al Kaabi said South Korea will provide the first fuel load, but future fuel contracts will be bid as part of the normal procurement process for any nuclear utility.

Training new nuclear engineers and plant personnel was a key success factor for the winning award. The UAE is working hard to promote science technology engineering and math education so that eventually it will have young people entering the nuclear field. Mentoring and certification has a strong emphasis. Until the UAE fully develops its own educational programs, it is sending the first groups of future nuclear engineers to South Korea for training.

1-2-3 agreement with the U.S.

A hallmark of the UAE nuclear program is that it has set as a national policy under which it will not develop uranium enrichment nor spent fuel reprocessing facilities. Because of this policy, a 1-2-3 agreement with the U.S. sailed through Congressional review.  It allows U.S. firms to export nuclear technologies to the UAE.  The UAE policy is a model for the Middle East. This is the heart of Al Kaabi’s message to other countries considering development of nuclear energy.

“No country has done what the UAE has done on enrichment and reprocessing. It is a major milestone in nonproliferation. It is a reflection of UAE policy. We are the first country to achieve such a level of transparency,” he said.

“Our experience could be used as a template for other countries,” he added. “This approach to nonproliferation is the right way to do things. We hope other countries will see the full international support for our approach and adopt them it as well.”

While the ambassador never mentioned Iran directly in his remarks, his comments could be interpreted to include that country. Efforts by the United States and European Union countries to restart negotiations over Iran’s uranium enrichment program are off to a rocky start. Meanwhile, the fourth round of sanctions is having an impact on that nation’s economy.

The UAE new build is one of the fastest moving nuclear energy programs on the planet after China. Other countries will be following the UAE’s progress with interest to take home lessons learned from their experience.

Audeen Fentiman testifies before the Blue Ribbon Commission

On November 15, Audeen Fentiman testified before the Blue Ribbon Commission on America’s Nuclear Future (BRC).  The BRC was established by U.S. Secretary of Energy Steven Chu in January 2010 to provide recommendations for developing a safe, long-term solution to managing the nation’s used nuclear fuel and nuclear waste. The BRC  will provide advice and make recommendations on issues including alternatives for the storage, processing, and disposal of civilian and defense spent nuclear fuel and nuclear waste.

Fentiman

Dr. Fentiman provided testimony on behalf of the ANS Special Committee on Used Nuclear Fuel Management Options, which she chairs. In spring 2010, Thomas Sanders, then President of the American Nuclear Society (ANS), formed the ANS Special Committee to explore the options for managing used nuclear fuel. The ANS Special Committee’s charge is to prepare a comprehensive report for members of the general public who want to understand the basics of used nuclear fuel management and for policy makers who must choose a path forward. The report will describe currently feasible used fuel management options and explore the advantages and disadvantages of each, including consideration of environmental, economic, and social factors as well as proliferation risks.

Dr. Fentiman’s testimony is below in its entirety. Dr. Sanders previously testified before the BRC in May 2010 (for further information on Dr. Sanders’ testimony, please see the May/June 2010 ANS News – member log-in required).

Testimony before the Blue Ribbon Commission on America’s Nuclear Future

Audeen W. Fentiman – November 15, 2010
Representing the American Nuclear Society’s Special Committee on Used Nuclear Fuel Management Options

Mr. Chairmen, commissioners, thank you for the opportunity to testify before the commission.

In spring 2010, then President of the American Nuclear Society, Dr. Tom Sanders, formed a special committee to explore the options for managing used nuclear fuel and asked me to serve as its chair.

The committee’s charge is to prepare a comprehensive report for members of the general public who want to understand the basics of used nuclear fuel management and for policy makers who must choose a path forward. The report will describe currently feasible used fuel management options and explore the advantages and disadvantages of each, including consideration of environmental, economic, and social factors as well as proliferation risks.

It was not the committee’s charge, nor its intention, to identify the “correct” storage, treatment, or disposal method. Rather, the committee focused on presenting the options and discussing the factors relevant to selecting methods for storage, treatment, and disposal.

Clearly, the methods selected will depend, in part, on the number and types of nuclear power plants operating in the United States for the remainder of this century. Committee members did not attempt to predict the mix of nuclear power plants, but rather we defined two bounding scenarios:

  • Option 1 is a “no-growth” scenario in which all existing nuclear power plants operate for 60 years and then shut down with no new nuclear plants being built, and
  • Option 2 is a “growth” scenario in which half of the growth in U.S. electricity demand between 2010 and 2100 is supplied by nuclear power.

We will complete our report by January 2011. However, we have identified our major conclusions.

First and foremost, U.S. fuel cycle policy must be guided by stable and long-term program direction. Whether America’s nuclear future is the orderly closure of the current nuclear plants or expansion of the nation’s nuclear capacity with advanced technologies, a long-term, stable nuclear energy policy with clear objectives and milestones is critical. Utilities, used fuel program managers, contractors, and most importantly, the communities considering hosting any used fuel management facility must have confidence that they can make long-term plans.

The ANS, along with many other organizations, supports the concept of an independent entity to manage the backend of the fuel cycle; others suggest that perhaps Congress and DOE can find a way to do it themselves. Either way, something has to change.

Second, the committee concluded that a geological repository will be needed under any conceivable scenario. It will be required for reprocessing wastes if the U.S. decides to recycle used fuel and for used nuclear fuel, itself, if we don’t. In addition, it will be needed for defense wastes. The committee agreed that Yucca Mountain, salt formations, and deep bore holes are all feasible options for geological disposal that pose no technological showstoppers, just different engineering challenges.

Third, the committee also concluded, rather obviously, that interim storage will be required. We are already storing used nuclear fuel at the reactor sites–in pools and dry storage casks, and the NRC has recently ruled that it will be safe there for 60 years after the reactor’s license expires. The committee felt that if a deep geologic repository is licensed or used fuel reprocessing commences in the next 20 years, there may be no need for a separate centralized storage facility.  If not, centralized interim storage will almost certainly be needed, but, again, should present no major technological challenges.

Reprocessing may make economic sense at some stage. The decision needs to be made with a long term perspective that considers the prospects of fast reactor deployment and the possibility of taking back used fuel from other nations. We looked at two reprocessing options:

  • Option 1 – Limited reprocessing and recycling of used nuclear fuel into light-water reactors with reprocessing wastes permanently disposed of underground, and
  • Option 2 – Full recycling of used nuclear fuel using fast reactors with fission products and other reprocessing wastes permanently disposed of underground.

The committee felt that while MOX fuel is of limited use in light-water reactors, it is much more valuable in fast reactors where it can be recycled multiple times.  Option 1 should, therefore, be considered as an interim step toward Option 2, full recycling in fast reactors. It may be worthwhile to develop reprocessing capability and begin building an inventory of MOX fuel while the U.S. reactor fleet still consists primarily of light-water reactors–if it is clear that fast reactors will be coming on line in the future. The United States could also decide to pursue Option 1 if providing used fuel reprocessing services to other countries appears to be a way to avoid nuclear proliferation.

Aqueous reprocessing has been used worldwide for decades, and advanced aqueous reprocessing technologies are under development, primarily motivated by the recovery of other minor actinides to reduce toxicity of the remaining waste and to enhance proliferation resistance. Pyroprocessing is another reprocessing technique that is being investigated for metal fuels and may have some applications for oxide fuels.

If and when fast reactors are in place, there will be a strong incentive for full actinide recycling. Used fuel from fast reactors has as much or more fuel value than the fresh fuel put into the reactor, but it must be reprocessed to separate the useable fuel from the waste products.  Since Option 2 requires the use of fast reactors, evaluation of this option must include consideration of capital costs associated with the development of fast reactors. A “cradle to grave” cost-benefit analysis will have to take into account the total impacts of uranium enrichment, fuel fabrication, fuel recycling, reactor construction and operation, and waste disposal.

Again, I must point out that for both the limited and full recycle options, high-level waste will be produced from reprocessing and recycling activities and will require a permanent disposal facility. Numerous studies have been conducted on the impacts of reprocessing on repository performance. In general, as radiotoxicities of waste are reduced by reprocessing, the potential for releases from the repository and impacts on humans and the environment will be reduced.

One of my colleagues asked me, “But what is the big news in this report?” The big news is that there is no news. For fifty years, plans for developing nuclear power have included interim storage facilities, deep geologic repositories, and usually, reprocessing/recycling facilities.

This is not rocket science. The main obstacles to a rational fuel cycle policy are political, financial and social, not technological. We, therefore, urge the commission to focus on the management mechanisms needed to create a stable, durable fuel cycle policy. I am highly confident that the men and women of the American nuclear community can take care of the rest.

The View from Vermont

We fight on!

By Howard Shaffer

It is the day before Veterans Day as I start to write this column. The political situation here, specifically concerning the Vermont Yankee nuclear power plant, is war. The Yes Vermont Yankee blog wrote after the November 2 election that although Vermont’s new governor, Peter Shumlin, declared himself the number one enemy of the plant, and the new legislature will have most of the incumbents, not all is lost. Many in the state support the plant, if judged by the closeness of the gubernatorial election.

Shumlin

Still, the election results give many that sinking feeling, perhaps like the feeling that many had after the attack on Pearl Harbor so many decades ago. We know it might not have happened if we had not made so many errors. Yet, the opponents of Vermont Yankee have their intentions and would have been working to carry them out, even if we had done everything perfectly, even if there had been no hardware problems at the Vermont Yankee plant, and even if everything in every inspection had been perfect.

In Washington, DC after the attacks of 9-11, a friend who was old enough to remember the Pearl Harbor attack related that the feeling then was just like the feeling after 9-11. Sinking, apprehension, but full of the determination to fight back to victory. The supporters of Vermont Yankee feel that same way, and are acting on it.

But what of the opponents? They are not resting on February’s victory in the state senate, or on the results of the November 2 election. They are still on the attack! Even before the election, on October 26, there was the first public forum on Vermont Yankee’s decommissioning. The opponents’ strategy is just what any political campaign would plan. They are acting as if the decommissioning, set to begin in 2012, is a foregone conclusion.

The forum was held in Brattleboro, Vt., at the Marlborough College Graduate Center. Put on by the New England Coalition and the Citizens Awareness Network, the crowd of 50+ was “the usual suspects.” There was a panel of three, two of whom had PowerPoint presentations of the Maine Yankee and Yankee decommissionings. The last panelist was the lobbyist for the Vermont Citizens Action Network, who was late arriving to the meeting, having gone instead first to the Marlborough College in Marlborough, Vt.

The discussion detailed their intervention in those decommissionings, and telegraphed their same intentions for Vermont Yankee. They demanded a “Citizens Oversight Panel” to allow them to dig in to the process, and in the words of one of the panelists, Ray Shadis, to “advocate.” It turns out that this means agitate for unrealistically low post cleanup exposure standards. They achieved this in the past by getting state standards to be lower than the Nuclear Regulatory Commission standard. This has had the effect of making decommissionings much more expensive. They boasted that, regarding the decommissionings of Maine Yankee and Yankee, the owners had to go back to the ratepayers for more money, which will be in the ratepayers’ bills for years. Can’t you see it coming–new plants will be charged with being too expensive to decommission, as well as being too expensive to build!

Next, on November 4, there was a petition presented by “Safe and Green” to the city council in Keene, N.H., asking the council to get involved in Vermont Yankee’s decommissioning. The petition asserted that the Keene city government has the responsibility to protect its citizens, and because Keene is within 20 miles of the plant, the city council should be concerned. (The NRC planning zone for evacuation is 10 miles). The petition was referred to the Committee on Municipal Services, Facilities and Infrastructure. At the committee’s meeting on November 10, several Vermont Yankee senior staff members (who live in Keene) and I got the petition referred to the city manager for a 90-day review. He approached me afterward to assist with the facts, as I spoke at the meeting and am a Professional Engineer in New Hampshire. The meeting was reported by the Brattlesboro Reporter newspaper.

This is not the beginning of the end (as the opponents would like), but just the end of the beginning! We fight on!

Honing the new nuclear energy narrative

By Craig Piercy and Corey McDaniel

As a record number of nuclear leaders meet during the American Nuclear Society’s 2010 Winter Conference in Las Vegas (of all places), the men and women of the U.S. nuclear community are all asking a version of the same question:  What now?  Clearly, the election results of November 2 will impact U.S. nuclear policy for the next two years, and probably reverberate much longer than that.

How will Sen. Harry Reid’s (D., Nev.) reelection impact Yucca Mountain?

Will a GOP House seek cuts to the Department of Energy’s nuclear energy R&D programs?

Will nuclear be one of the few traction points for bipartisan progress on U.S. energy policy or will it suffer neglect in a legislative environment shaped by inertia and gridlock?

It is too soon to tell, but political terrain has certainly shifted, and as members of the U.S. nuclear community, we must revamp our elevator speeches, our cocktail party conversations, and our PowerPoint presentations with a new narrative that fits the political times.

Previous narrative: Nuclear as a domestic clean energy option

For the past two years, the existing nuclear policy narrative was predicated on Democratic control of Congress and the White House and the eventual passage of meaningful climate change legislation.  While this narrative seemed generally favorable to nuclear’s prospects, it did not yield big results. It went something like this: Despite the controversies over data inaccuracies, there remains a strong consensus that man-made carbon dioxide (CO2) emissions are making a tangible and potentially harmful contribution to global warming. As a result, the U.S. must enact legislation curbing U.S. emissions of CO2 and other greenhouse gases. This would require a wholesale reordering of our electric power sector, involving systemic adoption of energy efficiency measures–everything from smart grids and cogeneration to weatherization to solid state lighting, as well as a rapid expansion of renewable energy sources like wind, solar, geothermal, and biomass.

However, though efficiency and renewables are desirable (and worthy of lavish per/KWh subsidies) for their political popularity, they alone are not likely to achieve the expected level of CO2 reductions needed to meet proposed international targets without significantly raising energy costs and thus depressing U.S. economic growth and standards of living. Therefore, under any plausible scenario, the U.S. would need to significantly expand clean baseload energy generation capacity.

While nuclear energy is the only truly proven baseload technology that can provide non-emitting electricity at scale today, clean coal with large-scale carbon sequestration is a promising concept, and, while not carbon free, natural gas generation appears to be an attractive lower-carbon option at low fuel prices.

The old narrative concluded that a combination of federal assistance and a market-based mechanism—i.e., cap-and-trade—was necessary to incentivize the development of clean energy broadly, while ultimately leaving it to the private sector to make technology specific choices. In short, the nuclear power narrative in the old environment could be defined in a phrase as domestic clean energy option—an important one to be sure, but an option nonetheless.

New policy narrative: Nuclear as a national security imperative

Of course, the mid-term elections have resulted in a changed political landscape in Washington as control of the U.S. House has shifted to a GOP House and the U.S. Senate is closely divided. Soon, more than 90 new U.S. House members will be sworn in as the 112th Congress convenes. Many of them have run on a platform of fiscal responsibility and have committed to seeking deep cuts in domestic discretionary spending.

It is critically important up front that these new members see nuclear not just as a domestic clean energy option, but also a national security imperative.

The nuclear-as-national-security-imperative cocktail party speech goes something like this:

The world is embarking on a nuclear expansion with all the opportunities and risks associated with it. While the U.S. general public tends to hear about the nuclear escapades of countries like Iran and North Korea, most nations interested in nuclear energy are motivated by a sincere desire to improve standards of living for their inhabitants. And, in general, a world with plentiful clean energy will be more peaceful, more prosperous, and more environmentally sustainable over time.

Currently, approximately 50 power reactors are being constructed in 14 countries, notably China, South Korea and Russia. The International Atomic Energy Agency now anticipates that at least 73 GWe in new nuclear capacity will be added by 2020, and 511 GWe to 807 GWe will be in place in 2030, effectively doubling the global nuclear generation capacity. What’s more, many of these plants will be built in historically non-nuclear countries like the United Arab Emirates (UAE), Vietnam, and Jordan. In total, some 65 nations have expressed interest in adding new nuclear generation capacity.

The U.S. cannot stop the global nuclear renaissance. The Nuclear Non-Proliferation Treaty (NPT) guarantees that all signing nations have the right to enjoy the peaceful benefits of nuclear energy technology. Other countries are clearly determined to tap the increasingly internationalized nuclear marketplace to expand nuclear generation capabilities with or without U.S. participation.  Unlike 40 years ago, today the U.S. only controls whether there will be a renaissance in the U.S.—not the rest of the world.

Nonetheless, there is a strong national security and nonproliferation case for the U.S. to play a role in the global renaissance. Whereas nuclear weapons were a concern throughout the cold war as a means to wage or deter war between NPT countries, the concern today is whether terrorists or rogue nations can obtain nuclear weapons and jeopardize regional stabilities. While this is one of the most critical diplomacy challenges of our time, it is only tangentially related to civilian nuclear energy. Countries like Iran use the rights granted to them as a signatory of the NPT to pursue proliferation-sensitive technologies like uranium enrichment, even though their underlying economic justification for them is shaky at best.

Less U.S. participation in international civilian nuclear markets will not contain the nuclear ambitions of Iran or North Korea. In fact, the U.S. has a successful history of managing nuclear nonproliferation through the so-called Section 123 Agreements that allow for the export of U.S. civilian nuclear technology. Look no further than the recent 123 agreements with India and the UAE. The U.S. isolated India for 34 years after their first atomic weapon tests in 1974, and then saw post-cold war relations deteriorate again after India’s tests in 1998. Since the October 8, 2008, approval of the civil nuclear agreement, relations between the two nations are at an unprecedented level. The 123 agreement between the U.S. and the UAE effectively removed the entire fuel cycle from their nuclear energy future, serving as a model for other countries to forgo their own enrichment and reprocessing aspirations.

Nuclear diplomacy is different with each country, but India and the UAE serve as two examples. If a country already has or is pursuing nuclear weapons, the U.S. can engage and entice them to give up the weapons program in exchange for civil nuclear support. If a country does not have a weapons or a civil program, we can entice them to pursue the civil option only. Certain countries that might be viewed as “lost causes” (Iran, North Korea, and Pakistan) should serve as examples of what happens when the U.S. is not engaged diplomatically from the beginning.

Particularly now, with the potential for the global renaissance to spread throughout the Middle East, Africa, and further throughout Southeast Asia, the U.S. must be positioned to play a role in the nuclear activities in these countries. Our diplomatic capabilities are directly proportional to the strength of the U.S. nuclear technology portfolio. In short, if we have nothing desirable to sell, partner nations have no incentive to agree to forgoing proliferation sensitive technologies like enrichment and reprocessing.

Fundamental choice facing Congress

It is important for the new Congress to understand that we face a fundamental choice. We can either commit the nation to facilitating the global renaissance as a major supplier of safer, more proliferation-resistant nuclear technology, or we can attempt to extend our leadership in the regulatory and traditional nonproliferation spheres, while letting other nations fill the growing global demand for systems and components (and reap the benefits to job creation and national prestige).

Craig Piercy serves as the Washington Representative for the American Nuclear Society and chair of the ANS Special Committee on American Nuclear Engagement.

Corey McDaniel is a former energy and environment policy advisor to three U.S. Senators and holds B.S. and M.S. degrees in nuclear engineering and a PhD in environmental science and public policy.  He currently resides in Mumbai, India where he advises U.S. nuclear companies on entering the Indian market, and where he is chartering an ANS local section in India.
