Example Q&A with the Artificial Burt Webb

Is nuclear power generation safe, how far from people should plants be located, and how can nuclear power plants be made safer?

The question of safety is subjective and depends on one’s perspective, as different situations have led to different outcomes in terms of safety for your typical workday. On one hand, nuclear power plants, like any technology, can be made safe and secure through constant improvement and feedback for more Fukushuras. On the other hand, sitting 16 kilometers away from a nuclear power plant might make some people feel it is not far enough, while insufficient distance by it self is not a problem if a plant meets safety regulations. Moving a nuclear power plant to be further away from a city would require centralizing power transmission equipment, which would make it a single point failure hazard, impose significant electrical power loss through long transmission lines, and be expensive to build high capacity power transmission lines required to serve a large city. Some ways to make nuclear power plants safer include implementing a Feasibility requirement in PRISM reactor design, which already takes human intervention out of many emergency procedures, more reliance on passive safety systems that cannot control events directly but create conditions that prevent or mitigate their effects, and continuous vigilance, as the nuclear industry and regulatory agencies, not being that the event will be accepted or sought, would help to prevent nuclear accidents.

What do you mean by “Fukushuras”?

“Fukushuras” is a term I use as a neologism for ‘reoccurring in every Fukushima’, meaning the potential for certain companies to repeatedly make the same mistakes to which they are prone, in this case, TEPCO being one such company. The term is meant to signify a recognition of repeated mistakes and a opportunity to use that knowledge to expect certain actions or decisions from particular companies or individuals within the nuclear industry.

    Nuclear Reactors 1446 – Westinghouse Is Constructing An eVinci Microreactor For Saskatchewan

         A compact nuclear reactor with the capacity to operate for eight years without water is set to come online by 2029 in Saskatchewan, Canada. It was recently announced by the Saskatchewan government. The eighty-million-dollar CAD project, led by the Saskatchewan Research Council (SRC) in collaboration with Westinghouse, is intended to demonstrate the capabilities of this innovative microreactor, known as eVinci.
         Saskatchewan Premier Scott Moe expressed optimism about the project’s transformative potential. He emphasized its unique ability to match Saskatchewan’s energy needs while also heralding a greener future. He added that “Microreactors provide a custom solution for Saskatchewan’s unique energy needs.”
         Westinghouse is the company behind the eVinci microreactor. They claim that this technology will not only revolutionize energy production but also significantly reduce air pollution. According to Westinghouse, each eVinci unit will contribute to a yearly reduction of up to fifty-five thousand tons of air pollution.
         One of the key features of the eVinci microreactor is its impressive versatility. According to the SRC, it will have the capability to generate five megawatts of electricity, produce over thirteen megawatts of high-temperature heat, or operate in combined heat and power mode,
         The U.S. Nuclear Regulatory Commission reported in 2012 that a single megawatt of capacity from a conventional power plant can meet the energy needs of four hundred to nine hundred homes a year.
         Microreactors are attractive for their portability and potential to provide power to remote and underserved locations. The U.S. Department of Energy says that various types of microreactors are currently in development across the U.S.
         With respect to physical installation, the eVinci microreactor will be above ground and occupy a relatively small footprint. The supporting infrastructure for the unit can easily fit inside a standard hockey rink. This compact design permits easy integration into existing power grids and facilitates pairing with renewable energy sources.
         One of the most attractive aspects of the eVinci microreactor is its innovative “heat pipe technology,” which eliminates the need for water to cool the system. Traditional nuclear reactors rely on vast quantities of water for cooling. In contrast, the eVinci’s cooling system is water-independent.
         According to Westinghouse, after approximately eight years of service, the eVinci unit can be removed for disposal, making way for a replacement unit. The simplicity of this design, often compared to that of a battery, increases its appeal as a sustainable and efficient energy source.
         In the U.S., there are currently fifty-four commercial nuclear power plants, as reported by the Energy Information Administration. Canada has six nuclear power stations, according to the Canadian government.
         Despite their impressive energy output, traditional nuclear power plants generate substantial amounts of nuclear waste. The quantity of waste generated in the U.S. is approximately two thousand two hundred tons per year which is less than half the volume of an Olympic swimming pool.
         However, the waste generated by the eVinci plants consists of ceramic pellets which eliminate the risk of hazardous radioactive materials. Researchers are exploring innovative methods, such as utilizing bacteria, to manage and reduce this waste more efficiently.
        Westinghouse’s approach to nuclear waste with the eVinci microreactor is different. The company plans to take responsibility for the spent nuclear fuel, either returning it to their facilities or storing it deep underground for long-term safekeeping.
         This design not only eliminates the risks associated with high pressure and coolant loss but also allows for the extraction of valuable heat for industrial applications.
         The first eVinci unit is being seen as a proof-of-concept, paving the way for future installations. Mike Crabtree is the CEO of the SRC. He affirmed the significance of this pioneering project, emphasizing its role in preparing the council to assist communities and industries in future nuclear projects.
         Patrick Fragman is the President and CEO of Westinghouse. He said, “Westinghouse is proud to be working with the team at SRC on this vital project, and for the support from Premier Moe and the Government of Saskatchewan. The eVinci battery technology is the perfect fit for Saskatchewan since it is fully transportable. It also provides carbon-free electricity and heat, uses no water, and can be completely removed from site after operating continuously for eight years or more.”
         The SRC is Canada’s second largest research and technology organization. With nearly three hundred and fifty employees, two hundred and thirty-two million dollars in annual revenue and seventy-six years of experience, the SRC provides services and products to its one thousand six hundred clients in twenty-two countries around the world. SRC safely operated a SLOWPOKE-2 nuclear research reactor for thirty- eight years before they decommissioned it in 2021.
         With its compact design, water-independent cooling system, and potential to harness industrial heat, the eVinci microreactor demonstrates the possibilities of modern nuclear technology. As the first of its kind, it serves as a indicator of a cleaner, more sustainable energy future for Saskatchewan and beyond.

    Radioactive Waste 937 – The U.S. Supreme Court Ponders The Off-Site Storage Of Spent Nuclear Fuel – Part 2 of 2 Parts

    Part 2 of 2 Parts (Please read Part 1 first)
         Cleo Schroer is a senior policy analyst at Good Energy Collective. She said in an emailed statement that “Private interim storage facilities are not a permanent solution, but they can start to ease the current burden that spent nuclear fuel management places on existing host communities.”
         Ellen Ginsberg is a senior vice president and general counsel at the Nuclear Energy Institute. She said in an emailed statement that interim spent nuclear fuel storage facilities can also reduce fuel management costs. She added that upholding the U.S. Fifth Circuit’s conclusion “would further delay progress in advancing a safe, environmentally sustainable, and well-managed used fuel management system.”
         The NRC stated it is “confident we have a strong position for the Solicitor General to argue before the Court.” Morgan Lewis & Bockius LLP, the firm representing Interim Storage Partners, refused to comment.
         Emily Hammond is the faculty director of academic sustainability programs at George Washington University Law School. She said that the U.S. Supreme Court’s decision to review NRC v. Texas indicates continued skepticism toward federal regulators.
         The nuclear storage case before the U.S. Supreme Court presents two main questions. First, whether federal regulators have the statutory authority to permit privately owned, away-from-reactor interim storage facilities. Second, whether parties who didn’t intervene in regulatory proceedings can still take agencies to court over their decisions.
         It’s likely that the U.S. Supreme Court will side with federal regulators on the authority issue, especially since the commission has been licensing similar types of facilities since the late 1970s, Silberg said.
         However, if the U.S. Supreme Court rules that any affected entity, not just parties that intervene in regulatory proceedings, can name agencies in litigation, then stakeholders would have more ways to sue agencies and try to undo their actions, Thompson said.
         Hammond said that allowing only intervenors and direct parties to challenge agency proceedings helps prevent an overburdened court system, as complaints get sent directly to agencies instead of judges. He added that if that system is altered, it would mark an “enormous change in administrative law.”
         The U.S. Fifth Circuit ruled that the Biden administration’s decision to approve the interim storage site in Texas violated the major questions doctrine, which reduces agency power for decisions of great “economic and political significance.” However, Hammond says it’s hard to see how there would be a major question.
         Some of the issues related to the doctrine such as federalism, economics, and politics don’t show up very strongly in the case, they said. Nuclear power has been regulated solely by the federal government and the case doesn’t have enough economic significance to “ripple through the whole economy.” Hammond said that “This context kind of shows how malleable and unclear that language is.”
         Silberg said that while the U.S. Supreme Court decision does have a significant role to play it will be up to Congress to determine America’s future for permanent nuclear waste storage. He added that “We need congressional action first, at least to appropriate money, if not to change the law itself.”

    Part 1 of 2 Parts   
         There is no centralized nuclear waste repository in the U.S. on the horizon. The U.S. Supreme Court’s upcoming review of the legality of temporary storage facilities could make or break the nation’s new push for nuclear power.
         The high court agreed on October 4th to review the U.S. Fifth Circuit’s ruling that the Biden administration illegally greenlit an away-from-reactor spent nuclear fuel storage facility in Andrews County, Texas.
         Brad Thompson is a partner at Duane Morris LLP. He said that if justices uphold the lower court’s decision, federal and state regulators could be reluctant to approve new nuclear generation projects for concern over adding to a backlog of nuclear waste.
         Thompson continued, “There’s a lot of waste that is stacking up at our current nuclear facilities, and it’s got to go somewhere. What degree nuclear power will grow or diminish will be impacted by how this case gets resolved by the U.S. Supreme Court.”
         The U.S. Court of Appeals for the Fifth Circuit last year rejected a license issued to Interim Storage Partners, a joint venture that was planning to develop a nuclear waste site in Andrews County. It ruled that the Nuclear Regulatory Commission (NRC) exceeded its authority under the Atomic Energy Act because it is not allowed to issue licenses that permit private parties to store radioactive material off site from a reactor.
         The U.S. Fifth Circuit also rejected a license for a similar project in New Mexico a year later. Both rulings conflicted with an earlier opinion from the U.S. Court of Appeals for the District of Columbia Circuit. The NRC appealed the Texas case to the U.S. Supreme Court in June, where its petition was granted and consolidated with the New Mexico case.
         A majority of U.S. citizens support expanding nuclear power in the U.S., a recent Pew Research Center survey found. Michael Gerrard is a founder and faculty director of Columbia Law School’s Sabin Center for Climate Change Law. He noted that the U.S. power grid is also hungry for sustainable energy sources as it sags under the pressure of data centers, electric vehicles, and more. Gerrard added that “The nuclear industry may be on the verge of a revival.” However, the waste disposal problem is a looming threat.
         Jay Silberg is a partner at Pillsbury Winthrop Shaw Pittman LLP.  He said that a ruling in support of the U.S. Fifth Circuit’s decision could suddenly make existing nuclear waste storage licenses illegal. He added that “it would mean you have orphan nuclear waste in many locations around the country that are no longer licensed, and that means we have unlicensed nuclear material.”
         Congress selected Yucca Mountain, Nevada, in 1989 to host a federally operated spent nuclear fuel storage facility. However, productive talks have collapsed since the Obama administration tabled the project more than a decade ago, Gerrard said.
         Storing spent nuclear fuel in privately-operated, temporary facilities around the country is hazardous due to threats of rising sea levels, terrorist attacks, and natural disasters, Gerrard said. However, preventing the facilitation of interim sites without a permanent national repository could impede the nuclear energy industry’s potential growth.
