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 1384 – Cameco Is Reporting Losses For 2023

    Nuclear Reactors 1384 – Cameco Is Reporting Losses For 2023

         Tim Gitzel is the CEO of Cameco, the Canadian nuclear fuel company. He said that the results for the first quarter of 2024 included losses of five million dollars. The losses were driven by normal quarterly variations, coupled with costs related to its acquisition last year of Westinghouse.
          Gitzel said, “In the first quarter operational performance was strong across our uranium, fuel services and Westinghouse segments. Financial results are in line with the 2024 outlook we provided, which has not changed, and are as expected, reflecting normal quarterly variability and the required purchase accounting and other non-operational acquisition-related costs for Westinghouse.”
         Gitzel added that first-quarter production results were “strong and are on track with our 2024 plans”. Attributable uranium production for the quarter was five million eight hundred thousand pounds of U3O8. This represents a year-on-year increase of one million eight hundred thousand pounds of U3O8. The mining operations at McArthur River/Key Lake and Cigar Lake are each expected to produce eighteen million pounds of U3O8 (on a one hundred percent basis) in 2024.
         Cameco closed its purchase of Westinghouse, in a strategic partnership with Brookfield, last November. Cameco now owns a forty-nine percent interest and Brookfield owns the remaining fifty-one percent. The company had previously said it expects this to generate a net loss of between one hundred and twenty-three million dollars and one hundred and sixty-seven million dollars in 2024 due to the impact of the purchase accounting, which requires the revaluation of Westinghouse’s inventory and other assets at the time of acquisition. Expensing of some non-operating acquisition-related transition costs will be included. Ninety million dollars of the expected net loss for Westinghouse in 2024 was incurred in the first quarter “due to normal variability in the timing of its customer requirements and delivery and outage schedules”.
         Westinghouse’s first quarter “is typically its weakest”, according to Cameco. This was stated in its quarterly in-depth management’s discussion and analysis (MD&A) document. Stronger performance is expected in the second half of the year, and higher expected cash flows in the fourth quarter. Gitzel said that the company was “delighted” with its acquisition of Westinghouse. He told investors that “It’s even better than we thought when we bought it. The potential there in all elements of their business is really good.”
         Production from the Inkai joint venture in Kazakhstan was slightly down year-on-year. One million six hundred thousand pounds of U3O8 produced this quarter compared with one million nine hundred thousand pounds in the same period in 2023 (both on a 100% basis). Inkai’s current production target for 2024 is eight million three hundred thousand pounds of U3O8 (100% basis). However, procurement and supply chain issues, most notably related to the availability of sulphuric acid, mean that this target is tentative.
         Cameco said that it is working with its closely with JV Inkai and its joint venture partner Kazatomprom to receive its share of production via the Trans-Caspian International Transport Route, which does not rely on Russian rail lines or ports. However, it warned that delays to deliveries could happen “if transportation using this shipping route takes longer than anticipated”.
         Cameco said that “To mitigate the risk of transportation delays or production shortfalls, we have inventory, long-term purchase agreements and loan arrangements in place we can draw on.”

  • Nuclear Reactors 1383 – Holtec International Is Spawning A Subsidiary To Provide Nuclear Services

    Nuclear Reactors 1383 – Holtec International Is Spawning A Subsidiary To Provide Nuclear Services

         Holtec International has established a wholly-owned subsidiary aiming to “energize the presently placid business sector of modification and maintenance”, with the initial project being the recommissioning of the Palisades nuclear power plant.
         Holtec Maintenance & Modification International (HMI) is based in Chattanooga, Tennessee. It is headed by Christopher Bakken. In its statement announcing the move, Holtec International said the new subsidiary’s mission was “to meet the time-critical maintenance and modification needs of the world’s operating nuclear power plants with assured performance certainty”.
         Holtec added, “To provide maximum value to its clients, HMI is poised to introduce cutting edge technologies such as AI-aided preventive maintenance and robot-led crew radiation dose reduction methods at its clients’ plants … we believe the HMI management model will bring about a vastly improved control of operating costs of nuclear plants and ensure heightened plant reliability, which will support the expected renaissance in nuclear generation around the world.”
         HMI will operate under Holtec’s programs on nuclear quality assurance, environmental protection, personnel safety assurance, corporate governance and supply management “but will be otherwise autonomous”. It will work with Holtec’s Nuclear Power Division “to provide replacement components and systems – reverse engineered as necessary to replace obsolescent items – to meet target outage schedules”.
         As well as its initial work on the project to restart the eight hundred and forty megawatt Palisades nuclear power plant, Holtec says that “discussions with other clients in the USA and overseas are under way”.
         Rick Springman is Holtec’s President of Global Clean Energy Opportunities. He said, “With the launch of HMI, we can now provide an integrated capability to meet the operating needs of the scores of SMR-300 plants that we hope to be building in the US and around the world.”
         Holtec agreed to purchase Palisades from then-owner and operator Entergy in 2018 ahead of the scheduled closure for decommissioning. The purchase was completed in June 2022, within weeks of the reactor’s closure. At that time Holtec planned to complete the dismantling, decontamination, and remediation of the plant by 2041. However, following the purchase, the company then announced plans to apply for federal funding to enable it to reopen the plant. Michigan Governor Gretchen Whitmer was amongst those pledging support for the action. The State of Michigan’s Fiscal Year 2024 budget was signed by Whitmer in mid-2023. The budget provides one hundred and fifty million dollars in funding towards the plant’s restart. In March, the US Department of Energy Loan Programs Office committed up to one billion five hundred and twenty million dollars for a loan guarantee to Holtec Palisades for its project to bring the Palisades plant back online. The intention is for the Palisades nuclear power plant to be back operating by the end of 2025.
         Holtec has also said it intends to locate its first two small modular reactor (SMR) units at the Palisades plant. It also hopes for to construct fleets of its one-hundred-and sixty megawatt SMRs elsewhere in Europe in such countries as Ukraine, the Czech Republic and the U.K.

  • Nuclear Reactors 1382 – ARC Clean Technologies Is Collaborating With Two Other Companies To Advance Deployment Of The ARC-100 SMR

    Nuclear Reactors 1382 – ARC Clean Technologies Is Collaborating With Two Other Companies To Advance Deployment Of The ARC-100 SMR

         A trilateral collaboration agreement has just been signed between Korea Hydro & Nuclear Power, ARC Clean Technology and New Brunswick Power with the goal of establishing teaming agreements for global small modular reactor (SMR) fleet deployment. This agreement follows the signing of a memorandum of understanding (MoU) last November.
         Through the MoU signed last year, the three companies have been exploring collaboration opportunities for the commercialization of ARC’s ARC-100, an advanced SMR, in Canada, South Korea, the USA and other jurisdictions where Korea Hydro & Nuclear Power (KHNP) has business operations.
         The new collaboration agreement was signed during the Reuters SMR and Advanced Reactor 2024 Conference in Atlanta, Georgia. It establishes commitments to deliverables, processes and timelines to advance discussions for participation and potential investment in the deployment of ARC units. The process will start with a commercial demonstration unit in the Canadian province of New Brunswick.
         ARC and NB Power have been working together on the development of the ARC-100 since 2018. In July of 2023, NB Power, in partnership with ARC, submitted an environmental impact assessment registration document and an application for a site preparation license for an SMR at the Point Lepreau nuclear power plant site in New Brunswick. This demonstration unit is expected to be commissioned by 2029, subject to approvals and licensing. The deployment of the ARC-100 in New Brunswick is part of a joint strategic plan on SMR development and deployment issued by the governments of Ontario, Saskatchewan, New Brunswick and Alberta in 2022.
         Jooho Whang is the CEO of KHNP. He said, “While we focus our capabilities on technological development for Korea’s Innovative SMR (i-SMR) to have the highest level of competitiveness in the world, we are pushing for timely entry into the 4th generation SMR market.” He added that “global cooperation is necessary for accelerating the development and construction of 4th generation SMRs, and the strengths of the leading companies in Canada as well as KHNP will lead to synergy in cooperation”.
         Bill Labbe is the ARC Clean Technology Canada President and CEO. He said, “We are excited to take the next step in formalizing our relationship through today’s agreement. ARC is seeing significant growth and interest from multiple heavy industries and global jurisdictions for use of our technology. Together, ARC, KHNP and NB Power will be first movers in the industry with a turnkey solution for commercial deployment.”

         Lori Clark is the NB Power President, CEO and Chief Nuclear Officer. She said, “Small modular reactors are an important part of NB Power’s strategic plan to meet government mandates to phase out coal by 2030 and achieve net-zero supply by 2035. The agreement with KHNP and ARC will assist us in deploying the clean energy we need to meet our climate goals and maintain energy security for New Brunswickers. In addition, we are excited about what this could mean for potential future commercialization opportunities.”
         The ARC-100 is currently undergoing the second phase of the Canadian Nuclear Safety Commission’s pre-licensing Vendor Design Review process. ARC Clean Technology completed the first phase in 2019.
