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 1473 – EDF Is Managing The U.K. Fleet of Commercial Nuclear Power Reactors – Part 1 of 2 Parts

    Part 1 of 2 Parts
         EDF Energy said the performance of its U.K. nuclear power plants in 2024 was “very good”, with an output of thirty-seven terawatts. It intends to maintain the same level over the coming years. Meanwhile, a new report has highlighted the contribution that nuclear energy has made to economic growth in the UK.
         EDF manages eight U.K. nuclear power plant sites. Five of them are currently operating (Sizewell B, Torness, Heysham 2, Heysham 1 and Hartlepool) and three have entered decommissioning (Hunterston B, Hinkley Point B and Dungeness B). It took over the nuclear power plants sites when it acquired British Energy in 2009. The company is also constructing the new Hinkley Point C plant in Somerset as well as advanced plans for a replica of Hinkley Point C at Sizewell C in Suffolk.
         EDF Energy said, “U.K. nuclear output in 2024 totaled thirty-seven terawatts – the same as 2023 – and nearly four times more than was anticipated for 2024 at the point of acquisition in 2009. The U.K. imported twenty-one terawatts from France in 2024, the majority of which will have been generated by French nuclear reactors. The objective is to sustain output at around this level into 2027 and longer, if possible.”
         EDF noted it has invested about ten billion dollars in the U.K. fleet since it acquired it in 2009 and will invest a further one billion sixty-two million dollars over the next three years (2025-27) “to help sustain current levels of generation, boost energy security and cut carbon.”
         EDF continued, “While output has dropped from a high point in 2016 of sixty-five terawatts from eight power stations, the fleet still plays an integral part in supporting U.K. energy security. This is especially true when demand is high and renewables output is low due to weather conditions.”
         EDF Energy said it has set itself a number of priorities over the next ten years.
         EDF said that the Sizewell B pressurized water reactor in Suffolk, which started operations in 1995, provides three percent of the U.K.’s electricity demand, “making it important for energy security and the UK’s clean power goals”. EDF said it will invest to enable a potential twenty-year operating extension, taking the lifetime from 2035 to 2055. “This decision is subject to agreeing the appropriate commercial model to ensure such an extension is viable.”
         Last December, further short life extensions for the four generating Advanced Gas Cooled Reactor (AGR) plants were announced. Heysham 1 and Hartlepool will generate until 2027, and Heysham 2 and Torness would have their lifetimes extended by two years to 2030. EDF said it wants to generate beyond these dates, subject to plant inspections and regulatory oversight.
         An agreement to remove the fuel from all seven AGR plants was reached in June 2021. Once the spent nuclear fuel has been removed, each plant will be transferred to Nuclear Restoration Services (NRS), part of the Nuclear Decommissioning Authority (NDA). There are three nuclear power plants currently in defueling (Hunterston B, Hinkley Point B and Dungeness B). EDF said its target is to make this transfer approximately nine to twelve months after each power plant is declared as ‘fuel free’. The first plant due to transfer will be Hunterston B in mid-2026. The  rest of the nuclear fleet is due to transfer on a rolling basis in the years that follow. This is dependent on actual end of generation dates and overall defueling performance at each station and at Sellafield.

         Edwin Lyman is the director of nuclear power safety at the Union of Concerned Scientists in Washington, D.C. He has a list of serious concerns about current storage methods. Lyman said, “If there’s no long-term plan to transfer that spent fuel to a more durable structure that can last for geologic time, then we can have a problem. real challenge of nuclear waste disposal is finding a way to make sure that it doesn’t affect the environment over this very long time period, that it’ll remain toxic.” Lyman has also said that the nation’s track record in storing spent nuclear fuel is not perfect.
         In 2018, workers moving a canister of spent nuclear fuel in California made an error and almost dropped the canister eighteen feet onto the floor of a concrete bunker. Lyman called this accident a near miss. According to government reports, the risks will only increase if more spent nuclear fuel has to be moved. Lyman also has other concerns like transportation accidents, sabotage and terrorism. He said, “A deliberate attack is certainly one way where you could maximize the potential harm to the community from that facility.”
         Lyman said that any community that considers building a temporary storage facility for the spent nuclear fuel needs to understand they would be accepting this waste without a long-term storage plan in place. He continued, “Because right now, there’s no plausible indication that it’s going to be going anywhere else. So they know they need to consider the fact that their community will ultimately be tagged as that permanent nuclear waste repository.”
         After Jeri Fry tuned into some of the nuclear waste discussions taking place in Northwest Colorado on YouTube last fall, she said she was saddened. A newspaper clipping detailing Jeri Fry’s father’s battle to win a workers’ compensation claim over his cancer that was linked to radiation exposure at the Cotter mill near Canon City hangs in Fry’s home.
         “Because it’s the same old game, and it’s very opportunistic,” Fry said about the federal government’s efforts to manage spent nuclear fuel. She is concerned that a community might raise its hand for a storage facility without being given a complete picture of the risks and should be asking a lot of questions. “If, as a community, we’re going to have to host this, ‘How long is that going on?.’” The containers that this (spent fuel) is in, are the containers going to last the life of the contents?”
         Opportunities for the public to ask questions will likely come soon. Public meetings on the spent nuclear fuel storage idea are being planned in Northwest Colorado. The DoE plans to formally ask which communities around the U.S. are interested in the idea, this fall.
         There are many concerns about the expansion of the U.S. nuclear power fleet. One of the biggest is how to deal with dangerous spent nuclear fuel generated during operation of commercial nuclear power plants. Without a permanent geological storage facility for the U.S., the spent nuclear fuel in temporary storage will only increase and continue to threaten public health and the environment.

         Jeri Fry isn’t a trained nuclear scientist. However, she does want communities to know about the history and risks of the nuclear industry. This includes the uranium that was mined and processed to feed those reactors.
         Fry said, “These things have half-lives that are centuries, millennia long. And so a community that is not given full disclosure and full information about what they’re signing on to, could just get a horrible commitment.”
         Historical nuclear waste with no permanent storage and large-scale nuclear disasters have caused many Americans to be distrustful of nuclear power.
          Anna Erickson is a professor of nuclear and radiological engineering in the Woodruff School of Mechanical Engineering at Georgia Tech. She also leads a research consortium sponsored by the DoE’s National Nuclear Security Administration. Major accidents at nuclear reactors like Chernobyl sparked Erickson’s interest in the subject of dealing with spent nuclear fuel. Erickson said, “It was done very carelessly in the past. It is not how we do things today. We have a lot better understanding of material associated with the uranium fuel cycle, and we do not think that depleted uranium is harmless anymore.”
         Erickson added that the scale of today’s waste from power plants is smaller and more manageable than the waste from nuclear weapons and fuel production left in places like Cañon City.
         Twenty years’ worth of spent nuclear fuel is stored at the former Maine Yankee nuclear plant. Nuclear experts say that the nation’s inventory of spent nuclear fuel would fit inside a football field and be about thirty feet deep. This kind of highly radioactive waste, primarily spent nuclear fuel, is stored in large cylinders made of concrete and steel.
         Erickson said, “If you take all of the spent fuel that’s been stored on site of nuclear reactors, and you consolidate it all, it’s (the) size of about a football field, right, about 10 yards deep. “Once the fuel is stored in those casks, the radiation around those casks is actually not that high. Those casks are regularly inspected today by humans with those Geiger counters that you’ve seen or other instruments. But in the future, we’re looking to move to robotics inspection.”
         Erickson continued that the U.S. has a good safety record while storing spent nuclear fuel on a temporary basis. “We have not had major accidents, or pretty much any accidents related to release of the material from those spent fuel casks.”
         According to a federal study from 2016, more than thirteen hundred spent fuel nuclear shipments have been completed safely in the United States over a thirty-five-year period. The report said that four shipments were involved in accidents, but “none resulted in a release of radioactive material or a fatality due to radiation exposure.”
         The Government Accountability Office calls the spent nuclear fuel that was shipped “one of the most hazardous substances ever created by humans.” Federal documents acknowledge that while many safety precautions are in place to prevent leakage of radioactive materials, there are risks to moving the fuel into the storage casks and transporting it. Citing several studies, the government says, “The key risk posed by spent nuclear fuel involves a release of radiation that could harm human health or the environment.”
