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 1303 – A Consortium of Companies Is Working On A Demonstration Lead-Cooled Reactor In Belgium

         Five companies from Belgium, Italy, Romania and the U.S. have signed a memorandum of understanding (MoU) to collaborate on the development and commercialization of lead-cooled small modular reactors (SMRs). The MoU is between Belgium’s SCK-CEN nuclear research center, ENEA (the Italian National Agency For New Technologies, Energy And Sustainable Economic Development), Italy’s Ansaldo Nucleare, Romania’s Regia Autonoma Tehnologii pentru Energia Nucleara (RATEN) and Westinghouse Electric Company of the U.S.
         The MoU was signed in Brussels in the presence of the Alexander De Croo, Belgium’s Prime Minister, Klaus Iohannis, Romania’s President and representatives from the Italian and US embassies in Belgium.
         SCK-CEN said, “With their combined efforts and shared drive to implement a cost-competitive energy-generating solution, the partners will nurture this promising technology, facilitating the commercial-scale deployment of sustainable nuclear energy,” SCK-CEN said, “The newly formed collaboration has outlined a clear vision, based on a step-wise approach to demonstration. Beginning with a small-size reactor to demonstrate the technological and engineering aspects of the commercial SMR-LFR in Mol, Belgium. The Lead-cooled Fast Reactor design developed by Westinghouse will be the starting point for this project ultimately targeting its global commercialization.”
         The consortium will work towards the next development phase, which is the construction of the Advanced Lead-cooled Fast Reactor European Demonstrator (ALFRED) in Pitești, Romania. It will focus on the technical and economic feasibility of future commercial SMRs. The partners will leverage and expand on the work done over the past ten years by Ansaldo Nucleare, ENEA and RATEN under the Fostering ALFRED Construction (FALCON) consortium toward this objective.
         A three-hundred-megawatt demonstration ALFRED reactor is being constructed at RATEN-ICN’s facility in Mioveni, near Pitesti. At that location, a fuel manufacturing plant is in operation for the country’s two operating Candu reactors. ALFRED is considered to be a prelude to an industrial demonstration reactor of about three hundred to four hundred megawatts. The lead-cooled reactor will employ mixed-oxide fuel. It will operate at temperatures around five hundred and fifty and will include passive safety systems. The total cost of the project is put at some one billion one hundred million dollars.
         The design of the ALRED reactor and the integrated project were led by Ansaldo Nucleare under the seventh Euratom framework program. ENEA performed the core design, technological development and safety analyses involving numerical and experimental approaches. 
    SCK-CEN said, “Thanks to the Myrrha (Multipurpose Hybrid Research Reactor for High-tech Applications accelerator-driven research reactor) project, SCK-CEN is a global leader in lead-bismuth research, and it will merge its acquired knowledge with RATEN’s extensive expertise in lead and ENEA’s widespread experience in lead technology development. Westinghouse Electric Company and Ansaldo Nucleare will bring extensive experience in design, licensing, construction and commercialization of nuclear power plants globally.”
          Prime Minister De Croo said, “A year and a half ago, we took the strategic decision to accelerate our energy transition. Reducing our dependence on fossil fuels, limiting our gas emissions and our dependence on countries like Russia, by investing massively in offshore energy, hydrogen infrastructure, but also the nuclear power of the future. We have decided to do this by drawing on the expertise developed in Belgium, and by allocating EUR100 million to the research and development of SMRs. From the beginning, we are convinced that this would be set up in cooperation with international partners. The agreement SCK-CEN has just signed today with Ansaldo Nucleare, ENEA, RATEN and Westinghouse is the first visible milestone in this strategy, a solid foundation on which we will continue to build.”

    Nuclear Reactors 1302 – NRC Answered Questions About Pilot Natrium Project From Citizens In The Kemmerer, Wyoming Area – Part 2 of 2 Parts

    Part 2 of 2 Parts (Please read Part 1 first)
         Typically, the complex and difficult NRC review can take seven years or more to complete. There is no guarantee that the project in question will receive final approval. Last year, the NRC denied Oklo Power, LLC’s application to construct a “fast reactor” in Idaho for allegedly failing to supply sufficient information on the facility’s design.
        TerraPower is embarking on its first NRC licensing attempt. It hopes to win approval much sooner, however, thanks in part to the 2019 Nuclear Energy Innovation and Modernization Act. The law was championed by Senator John Barrasso (R-Wyoming). It set a maximum review timeline of thirty-six months. Additionally, TerraPower expects to assist the NRC to trim that timeline even further by filing information ahead of schedule.
         The process all depends on TerraPower submitting thorough information that does not require many requests to get answers to ignored questions, according to the NRC.
         Jessup said, “If we have all of these discussions and address all of these topics before the application even comes in, then you would expect that it may make the review go faster.”
         Many locals are eager for the potential economic boon the four-billion-dollar project might bring to this region. Its economy has long relied on the diminishing coal industry to power the economy. However, many of the same people, and others, are concerned about the high-stakes risks that come with the nuclear facility.
         With respect to the question about checking for seismic activity, the NRC said that they are aware that there is seismic activity in the Rock Mountain Region.
         Several residents, including Representative Scott Heiner (R-Green River), asked when the spent nuclear fuel might be transported to a permanent storage facility. Heiner asked, “Is there a permanent solution for waste that is being worked on at this time?”
         The NRC responded that there is no permanent nuclear fuel waste repository in the U.S. at this time. Although, the NRC staff in attendance indicated that they “anticipate” one will be constructed, others have long indicated that there is no clear path to the construction of a permanent repository. Such a repository has been discussed for decades.
         The U.S. government passed the Nuclear Waste Policy amendments in 1987 promising a spent nuclear fuel repository. In 2002, Congress approved an old salt mine under Yucca Mountain in Nevada as the site for the repository in 2002. Millions were spent preparing the site until politics resulted in the cancelation of the project in 2011. There will not be such a repository in the U.S. before 2050 at the earliest. For the present, that means that spent nuclear fuel will be “temporarily” stored on site.
         The NRC also took questions about how nuclear fuel will be transported to the facility and how the safety of those radioactive materials will be ensured. The NRC, along with several other federal agencies, closely manages the transportation of such radioactive materials in cooperation with state agencies, according to NRC staff. A specific plan will be worked out in the NRC’s review.
         NRC representatives also reassured locals that they will maintain partnerships with the local emergency managers and state environmental authorities.

    Nuclear Reactors 1301 – NRC Answered Questions About Pilot Natrium Project From Citizens In The Kemmerer, Wyoming Area – Part 1 of 2 Parts

    Part 1 of 2 Parts
         TerraPower is backed by Bill Gates and the U.S. Department of Energy (DoE). It plans to construct the pilot “Natrium” liquid-sodium-cooled nuclear energy plant in Kemerer, Wyoming. TerraPower hopes that its success will spur the deployment of Natrium and other small nuclear reactors (SMRs) around the world.
         The next-generation nuclear technology presents a variety of considerations for the Nuclear Regulatory Commission (NRC). It would also be the first industrial nuclear facility in Wyoming. The local people have many questions including whether or not the NRC takes seismic activity into account, when the spent nuclear fuel be shipped to a permanent storage facility and, will there be regular NRC inspections.
        Senator Dan Dockstader (R-Afton), however, shares another concern that is front and center for locals who are eager for the economic boost that developers promised: Can the NRC accelerate the approval process “if you get the right people into place?” He said, “I’m running out of time planning and creating legislation to make sure this all comes together.”
         Dockstader was among more than one hundred local residents who came to the NRC’s two information in Kemmerer recently. The NRC sent a dozen staff member to this isolated southwestern Wyoming town of two thousand four hundred to take questions about what many anticipate will be an expedited review process.
         TerraPower and its contractors have already drilled more than a hundred boreholes in Kemmerer to help “investigate” the suitability of the chosen location, according to the company. It plans to begin building the sodium testing facility and other non-nuclear portions of the three hundred forty-five megawatt Natrium nuclear reactor plant in 2024.
         The new commercial nuclear power plant will be “co-located” next to PacifiCorp’s Naughton power plant just outside Kemmerer. One coal-burning furnace at the plant was converted to nuclear gas. The two remaining coal-burning units will be converted to natural gas in 2026.
         Before TerraPower can start assembling the nuclear components, however, it must complete a licensing application that can pass the NRC’s review process. There will be several opportunities for the public to weigh in on the proposal. The NRC expects to receive TerraPower’s application and begin the official process in March.
          William Jessup is NRC’s Chief of Advanced Reactor Licensing. He said, “Now is an opportune time to conduct this initial outreach and to explain the analysis process of reviewing applications for construction and operation.”
         Natrium uses molten sodium as a coolant instead of water. Although the NRC is developing a new review process specific to “advanced” reactors such as Natrium, TerraPower has tentatively agreed to seek approval via the long existing “Part Fifty” review. It includes multiple review tracks, each with safety and environmental components. One review considers a construction permit. A second review considers an operating license. The process requires the NRC to produce an environmental impact statement. All of the reviews include public input and multiple opportunities for the normal administrative and legal challenges that come with bit federal permitting activities.
