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 1063 – Russian Actions At Zaporizhzhia Threaten Nuclear Disaster

          I have been following the Russian occupation of the Zaporizhzhia nuclear power plant in the Ukraine. A lot of damage has been done in and around the plant. There is great international concern that the Russians may do something stupid and release radiation that could spread across Europe. Now comes a report about possible problematic Russian actions at Zaporizhzhia that could lead to a nuclear disaster. I hope that it is not true.
         There have been unconfirmed reports that Russian forces at the Zaporizhzhia nuclear power plant could be attempting to drain the cooling pond at the plant. They supposedly want to drain the cooling pond so they could conduct weapons searches. Dorfman said that this would be insane and warned of disaster if the Russian forces carried out their plan. He added that “Draining spent nuclear fuel ponds would be utter madness, as cascading problems could lead to very significant radioactive release – and depending on which way the wind is blowing, the radioactive pollution could either go to Europe or Russia.”
          Dorfman’s comments followed unconfirmed reports that a Ukrainian diver at Zaporizhzhia had died after being beaten by Russian soldiers because he refused to enter the cooling pool. This story was reported by the Kyiv Independent with quotes from the Mayor of Enerhodar. The title of the Independent story was Russian forces torture diver at Zaporizhzhia Nuclear Power Plant to death.
         “Enerhodar Mayor Dmytro Orlov reported on July 3 that Andrii Honcharuk died in hospital after he was brutally beaten by Russian forces for refusing to dive into [a] pool at the plant.”
          Dr. Dorfman said that it was obvious that the Ukrainian staff at the nuclear power plant were working “under duress”. He continued, “The fact is, one significant wrong step, one incident will change everything, irrevocably. Both for Ukraine and also for the global nuclear project. Even [the] Nuclear Energy Agency admits profoundly limited real-time information about what’s really happening on the ground. It’s a shooting war, after all. So, the Russian invasion of Ukraine unveils the reality of the weaponization of civil nuclear. It’s clear that Ukraine’s nuclear workers are under huge duress – and that could lead to very troubling consequences. Nuclear is a high-risk endeavor, after all.”
          This is not the first time that events at Zaporizhzhia have triggered anxiety among experts with knowledge of nuclear power plants. Earlier this year, there was a fire in an outbuilding. The plant itself sustained damage due to Russian shelling. Dr. Dorfman remarked, “I didn’t sleep at all for a few days.”
         There are six nuclear power reactors at Zaporizhzhia. Currently four of the six are shut down or are in the processed being cooled. This was reported by the Nuclear Energy Agency (NEA). The Observatoire Départemental d’Equipement Commercial (ODEC) NEA is an intergovernmental agency that works on nuclear technology, science, law and safety.
         One major argument against nuclear power is the problems that would arise if a nuclear reactor were located in a war zone. This was hypothetical until the Russians seized Zaporizhzhia.

  • Nuclear Reactors 1062 – U.S. Department Of Energy Is Studying Transitioning Retired Coal Power Plant Sites To Nuclear Power Plants

    Siting a nuclear power plant at the site of a recently retired coal power plant is referred to a coal-to-nuclear (C2N) transition. Such conversions could help increase the U.S. nuclear capacity to over three hundred and fifty gigawatts. The U.S. Department of Energy (DoE) report on C2N conversions is titled Investigating Benefits and Challenges of Converting Retiring Coal Plants into Nuclear Plants. The current U.S. nuclear reactor fleet has a combined capacity of ninety-five gigawatts.
         The new report is supported by a previous study carried out by the Argonne, Idaho and Oak Ridge National Laboratories, sponsored by the DOE Office of Nuclear Energy. It was guided by three questions. First, where in the U.S. are retired coal facilities located and what factors make a site feasible for transition? Second, what factors of technology, cost and project timelines drive investor economics over such a decision? Third, how will C2N impact local communities?
         The researchers screened recently retired and active coal plants to identify one hundred and fifty-seven retired and 237 operating coal plants as potential candidates for a C2N transition. These sites were then evaluated on parameters including population density, distance from seismic fault lines, flooding potential, and nearby wetlands in order to determine if they could safely host a nuclear power plant. The study found that eighty percent of the potential sites are suitable for hosting advanced nuclear power plants of various sizes and types. This will depend on the size of the site being converted.
          The team then evaluated a case study of detailed impacts and potential outcomes of a hypothetical site. They considered various nuclear technology types for a range of scenarios including big light-water reactors, small modular reactors, sodium cooled fast reactors and very high temperature reactors.
          At the regional level, replacing a big coal plant site with a nuclear power plant of equivalent size could provide some six hundred and fifty jobs and two hundred and seventy million dollars of economic activity. These jobs are distributed across the plant, the supply chain supporting the plant and the community surrounding the plant. Most typically come with wages that are about twenty five percent higher than any other energy technology. Nuclear power plant projects could also benefit from preserving existing experienced workforces in communities around the retiring coal plant sites. These workers already possess the necessary skills and knowledge that could be transitioned to work at a nuclear power plant.
          Repurposing existing coal infrastructure for new advanced nuclear reactors can lead to construction cost savings of fifteen to thirty five percent. Using existing land, grid connections, office buildings, electrical equipment such as transmission connections and switchyard and civil infrastructure could also save millions of dollars.
          Economic potential exists for owners of coal power plants and the communities in which they are located to benefit from a C2N transition. There would be future advantage for interested coal communities to be “first movers” in what the authorities say could possibly be a series of many C2N transitions across the U.S. Although the findings of the study inform only at a general level, the results could be used to generate more detailed, in-depth analyses to allow more accurate evaluations specific to a particular coal plant or nuclear technology design.
         The report was subjected to independent peer review by experts in systems engineering and regional economic modeling to validate analysis and assumptions.  
         The possibility of replacing coal power plants with nuclear power plants is being actively explored in the U.S. and elsewhere. In 2021, TerraPower announced plans to build a demonstration unit of its Natrium sodium-cooled fast reactor at a retired coal plant site in Wyoming. Earlier this year, the Maryland Energy Administration announced its support for work to evaluate the possibility of repurposing a coal-fired electric-generating facility with X-energy’s Xe-1 small modular reactor. Holtec International recently mentioned that it is considering coal plant sites as possible locations for its SMR-160 with plans to bring the first unit online as early as 2029. In Poland, NuScale is collaborating with energy company Unimot and copper and silver producer KGHM to explore possibilities for its reactor to replace coal-fired power plants.
