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 Fusion 39 – Marvel Fusion And Colorado State University Create A Public-Private Partnership To Develop Laser Fusion

    Nuclear Fusion 39 – Marvel Fusion And Colorado State University Create A Public-Private Partnership To Develop Laser Fusion

         Marvel Fusion is a German laser fusion developer. They have joined with Colorado State University (CSU) to create a public-private partnership for the construction of a one hundred- and fifty-million-dollar high-power laser and fusion research facility on the CSU Foothils Campus.
         This project is scheduled for completion in 2026. It would feature at least three laser systems. Each of these would have a multi-petawatt peak power and an ultra-fast repetition rate of ten flashes per seconds. The site selected for the new laser facility is near CSU’s existing Advanced Beam Laboratory built in 2013 on the CSU Foothills Campus.
         Marvel said, “Such a combination of lasers will make the facility unique in the world, and it would be designed to accommodate expansion and additional lasers in the future.” The state-of-the-art facility will serve as a platform to advance the company’s laser-driven fusion approach.
         The partnership is pending finalization of the financial details by the CSU Board of Governors. It will establish Fort Collins as a nexus for laser fusion research. It will also deliver significant positive impacts to Colorado.
         Moritz von der Linden is the CEO of Marvel. He said, “This public-private partnership sets the global standard for laser-based fusion research, propelling the development of a safe, clean, and reliable energy source. It is an incredible step forward for Marvel Fusion and a testament to our success and vision. Working with the world-class team at CSU over the past two years has been invaluably productive. We are immensely grateful for the trust and support of CSU, the State of Colorado, and the US Department of Energy’s (DOE’s) ongoing support through the LaserNetUS program.”
         Amy Parsons is the CSU President. She said, “CSU is at the cutting edge of laser research, and this new partnership will cement the university as an international leader in an area of laser science that has the potential to deliver profound benefits to our planet for generations.The project also would drive meaningful, long-term economic and reputational benefits to Fort Collins and the state.”
         Marvel is also planning the construction of a prototype as the next step toward a commercial fusion power plant. The prototype will host hundreds of laser systems capable of achieving fusion ignition and proving the technology at scale.
         Marvel noted that ongoing scientific and technological initiatives in Europe will continue to play a vital role in its research and development. These initiatives include experiments at Ludwig-Maximilian-University Munick’s CALA laser and the ELI-NP laser in Romania.
         In Marvel’s approach, an ultrashort laser pulse initiates the fusion process by interacting with small fuel pellets in a target structure with high intensity. The rapid impact of laser energy triggers the fusion of the fuel’s nuclei before the target structure can disintegrate. In order to achieve sufficient scale for commercial operation, fuel pellets will need to be irradiated and ignited several times a second.
        An injector inserts a new pellet into the target chamber where it is hit by incoming laser pulses and releases energy during the fusion process. Supplementary systems convert the released energy into electricity. By adjusting the rate of pellet injections and synchronized laser pulses per second, Marvel’s fusion power can adjust the overall energy output to market demand.

  • Nuclear Reactors 1253 – Taiwan Chinese Nationalist Party Would Like To Restart Decommissioned Nuclear Power Reactors

    Nuclear Reactors 1253 – Taiwan Chinese Nationalist Party Would Like To Restart Decommissioned Nuclear Power Reactors

         Taiwan currently has one nuclear power plant with two nuclear power reactors in operation. In 2015, they closed three reactors. Work had begun on a new nuclear plant called the Fourth National Nuclear Plant in 1999 but a series of construction problems and political opposition halted construction several times. One reactor was finished but sealed after safety inspections. The construction of a second reactor was stopped.
         Hou You-yi is the mayor of New Taipei City. He is currently running as the Chinese Nationalist Party (KMT) candidate to be the president of Taiwan. Environmental groups challenged the candidacy of Hou yesterday because they said that the energy platform of his party contains no feasible plan to deal with spent nuclear fuel rods.
         Former vice premier Woody Duh accompanied Hou as he presented the national energy platform for the party which is running him for president. Hou said that Taiwan’s transition to renewable energy would necessitate reactivating two decommissioned nuclear power plants. He also said that the decision to halt construction of the Fourth Nuclear Power Plant in New Taipei City’s Gongliao District would need to be reviewed. The key to reducing carbon emissions by Taiwan is to cut down on burning fossil fuels according to Hou.
        Hou said that if he were elected president, he would conduct maintenance and safety inspection of the two decommissioned nuclear power plants to see if it would be practical to extend their lifespan. He also said that he would get experts to assess the possibility of restarting work on the Gongliao plant. The two major goals of Hou’s green energy platform are a “low-carbon Taiwan” by 2035, a “zero-coal Taiwan” by 2040 and a “net zero Taiwan” by 2050.
         However, the Green Citizens’ Action Alliance and other environmental activist groups said that Hou and the KMT have never offered a solution for handling and disposing of spent nuclear fuel rods. It was claimed that Hou and the KMT are trying to deceive the public into believing that nuclear energy is a “miracle cure” that can solve the nation’s energy problems.
         Tsui Shu-hsin is the alliance secretary-general. She said, “As the KMT’s presidential candidate, Hou cannot evade these critical questions, including how to ensure nuclear plants operate safely, how to treat the spent fuel rods, where to store the nuclear waste and other pivotal issues. Their thinking is to reduce natural gas, replacing it with nuclear power to achieve green energy goals. In doing so, they are ignoring the long-standing problems, including Taiwan’s frequent earthquakes and operational safety issues, and there is no space for nuclear waste storage.”
         Tsui went on to say that if Taiwan’s decommissioned nuclear power plants were restarted, the rate of mechanical failures and breakdowns would be much higher than in the past. She added that it was possible that the old plants could not pass safety inspections.
         Hou also wants to review and restart the Fourth Nuclear Power Plant, which would be a step backward. Tsui asked if “we are going to waste another 10 years on its construction, and throw another NT$50 billion [US$1.57 billion] down this bottom-less pit?”

  • Nuclear Reactors 1252 – Nuclear Industry Group Calls For Action On Regulations For Small Nuclear Reactors

    Nuclear Reactors 1252 – Nuclear Industry Group Calls For Action On Regulations For Small Nuclear Reactors

         The Breakthrough Institute, Clean Air Task Force, ClearPath, Nuclear Innovation Alliance, and Third Way have joined together to issue a statement that says that delays in finalizing a regulatory rulemaking on risk-informed emergency preparedness has already caused significant regulatory uncertainty for developers.
         The proposed rulemaking is detailed in a document titled Emergency Preparedness Requirements for Small Modular Reactors and Other New Technologies. It would amend the U.S. regulations to add new emergency preparedness requirements for small modular reactors (SMRs) and other new technologies such as non-light-water reactor. It would also enable emergency plannings zones fore such reactors to be scalable to take into account their smaller size, lower power densities and lower probability of severe accidents.
         The proposed rule was published for public comment in May 2020. The comment period ended in September of that year. The final rule package was submitted to the NRC commissioners for approval in January of 2022.
          The five pro-nuclear groups say in a joint letter to the US regulator that “Commissioners are generally expected to vote on final rules in 60 days, but in this case the final rule publication date has been extended multiple times without explanation. Currently, the NRC rulemaking page says the final rule is scheduled for publication on 3 January, 2024. If this timeline holds, it would mean a duration of over 2 years since the final rule was submitted to the Commission for approval. This is in stark contrast to the NRC’s Efficiency principle of good regulation which states ‘Regulatory decisions should be made without undue delay’.” 
         The extensive delay is causing regulatory uncertainty for developers who are preparing licensing applications according to the group. Until a final decision is made, future applicants find themselves faced with the prospect of preparing two emergency preparedness. One plan would be based on the assumption that the rule will be in effect when they submit their applications. Another contingency plan would be drawn up in case the rule is not yet finished.
         This uncertainty has already resulted in applicants changing their emergency preparedness approach during the pre-application engagement process. Some delayed pre-application engagement until there is a greater certainty around what procedures will be available. It creates an extra burden for NRC staff, reduces the value of pre-application engagement for applicants and the NRC. The situation discourages future applicants. It is also contrary to the Nuclear Energy Innovation and Modernization Act of 2019. This bill directed the NRC to develop and implement strategies for the increasing use of risk-informed and performance-based licensing processes within two years. The groups said, “The NRC is over two and a half years late on this statutory deadline.”
          “A decision on the final emergency preparedness rule would increase regulatory predictability, reduce the regulatory burden for the applicant and the staff, and align with Congressional direction. More efficient and effective licensing contributes to meeting national environmental and energy security objectives. The Commission should act expeditiously to approve the final rule and update the associated Regulatory Guide 4.7, in the public interest.”

  • Nuclear Reactors 1251 – Cameco And Brookfield Business Partners Seek To Acquire Westhinghouse

    Nuclear Reactors 1251 – Cameco And Brookfield Business Partners Seek To Acquire Westhinghouse

         The U.K.’s Competition and Markets Authority (CMA) has invited comments on the propose Cameco and Brookfields Renewable Partners acquisition of Westinghouse Electric Company. The CMS is considering whether the deal “may be expected to result in a substantial lessening of competition in the United Kingdom.”
         In a statement posted on its website, the CMA said that  for the next two weeks, until the 16th of August, it is running an “Invitation to Comment” on the purchase. It was  “considering whether it is, or may be the case, that this transaction, if carried into effect, will result in the creation of a relevant merger situation under the merger provisions of the Enterprise Act 2002 and, if so, whether the creation of that situation may be expected to result, in a substantial lessening of competition within any market or markets in the United Kingdom for goods or services. To assist it with this assessment, the CMA invites comments on the transaction from any interested party.”
         Cameco said that this was part of the standard regulatory approval process for such transactions. It expects to close the deal by the end of this year.
          The proposed deal was unveiled in October of 2022. It calls for a strategic partnership of Cameco and Brookfield Partners to acquire Westinghouse for a total enterprise value of eight billion dollars. It would allocate fourty-nine percent of Westinghouse ownership to Cameco and fifty one percent ownership to Brookfield Renewable and its institutional partners.
         Westinghouse is one of the world’s biggest nuclear services businesses. It can trace its energy industry roots back more than one hundred years. Brookfield Business Partners acquired Westinghouse out of bankruptcy in 2018. Today, Westinghouse has four key business lines. These include providing services for outages and maintenance, engineering solutions and replacement components and parts; long-term contracting for the manufacture and installation of fuel assemblies and ancillary equipment for light-water reactors; designing, engineering and supporting the development of new nuclear reactors; and providing environmental services which support nuclear sustainability, environmental stewardship and remediation. It is the original equipment manufacturer for around half of the world’s nuclear power plants.
         Canada’s Cameco is one of the biggest global providers of uranium fuel “with interests in tier-one mining and milling operations that have the licensed capacity to produce more than 30 million pounds (our share) of uranium concentrates annually, backed by more than 469 million pounds (our share) of proven and probable mineral reserves. We are also a leading supplier of uranium refining, conversion and fuel manufacturing services”.
         Cameco’s second quarter financial results were released on Wednesday. Tim Gitzel is the CEO and President of Cameco. He said, “We are invested across the nuclear fuel cycle, and are looking forward to closing the Westinghouse acquisition with our partner Brookfield Renewable Partners, which we expect will occur later this year. We will continue to do what we said we would do, executing on our strategy, and, consistent with our values, we will do so in a manner we believe will make our business sustainable over the long-term.”
