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 1461 – BWXT Acquires Kinetics For Five Hundred And Twenty Five Million Dollars

    Nuclear Reactors 1461 – BWXT Acquires Kinetics For Five Hundred And Twenty Five Million Dollars

         The five hundred- and twenty-five-million-dollar acquisition of the Canadian nuclear services company Kinetrics by BWXT “creates a comprehensive portfolio of end-to-end lifecycle services for customers in the small modular reactor and traditional large-scale nuclear reactor markets”.
         Toronto-based Kinectrics operates two core business areas: commercial power services and nuclear medicine. Its commercial nuclear services portfolio includes support for all stages of the nuclear power plant lifecycle, and it is also a supplier of medical radioisotopes including lutetium-177.
         Rex Geveden is the BWXT President and CEO. He described Kinectrics as a “strong and growing nuclear services company with a comprehensive portfolio of offerings to commercial nuclear players globally”, with a wide base of customers, many of which are new to BWXT.
         The combination of these capabilities with the products and services of BWXT’s Commercial Operations segment will enable an expanded portfolio of products and services for current and new customers in the global nuclear power and radiopharmaceutical industries, BWXT said. “In the commercial nuclear power market, Kinectrics brings a broad suite of lifecycle support services that will further strengthen BWXT’s position in the CANDU reactor market, while increasing its exposure to the US market and select international markets.”

         John MacQuarrie is the BWXT Commercial Operations President. He said, “This acquisition expands our ability to deliver end-to-end solutions to existing and new customers more efficiently.” He added that the investment “uniquely brings together two industry leaders with complementary expertise and service offerings in the growing commercial nuclear power and nuclear medicine markets” and will improve the company’s ability to meet evolving customer needs. “This includes supporting utilities as they explore ways to expand nuclear power generation through life extensions and new builds, partnering with small modular reactor designers seeking comprehensive regulatory, engineering, manufacturing, and aftermarket solutions, and collaborating with healthcare partners who require reliable isotopes for under-supplied medical isotopes revolutionizing oncology.”

         Kinectrics produces ytterbium-176 which is a stable isotope used for the production of non-carrier-added lutetium-177 through irradiation at the Bruce nuclear power plant. Geveden told investors that production of lutetium-177, through the Isogen joint venture partnership with Framatome, is not expected to change. The Kinetics acquisition “adds a very important therapeutic isotope to our portfolio”.
         Turning to small modular reactor projects, Geveden said the combination of Kinectric’s offerings in project areas such as design, engineering, project integration and field testing would be complementary to BWXT’s manufacturing capabilities. Kinectric’s transmission and distribution project area would be vital for distributing the power to customers or to direct users such as data centers. “We’re trying to create an ecosystem [for small modular reactors] … as customers select partners long-term, we have the whole map figured out.”
         Kinectrics employs more than thirteen hundred engineers and technical experts located across its twenty sites worldwide. The Kinectrics acquisition is targeted to close in the middle of this year. It will nearly double the workforce of BWXT’s Commercial Operations and expand its capabilities, including lifecycle management, specialized plant services and engineering, to support the North American and international nuclear markets, the company said. Kinectrics will operate as a BWXT subsidiary, and its financial results will be reported within BWXT’s Commercial Operations segment. Its current President and CEO David Harris will continue to lead the organization, reporting to John MacQuarrie.
         BWXT said that it expects the investment to be “modestly accretive to BWXT’s earnings”, is “one of BWXT’s strategic steps in response to current and anticipated demand for nuclear projects and services worldwide”. BWXT, announced in 2024 a sixty-million dollar expansion at its facility in Cambridge, Ontario, to increase the plant’s footprint by twenty five-percent and create more than two hundred long-term jobs for skilled workers, engineers and support staff in the area.
         The announcement of the Kinectrics acquisition came right after BWXT completed its acquisition of L3Harris’ Aerojet Ordnance Tennessee, Inc. It is the provider of advanced speciality materials, fabrication and high-strength alloy manufacturing and is also the sole provider of depleted uranium to the US government, and will operate within BWXT’s government operations segment.

  • Nuclear Reactors 1460 – Deep Fission And Endeavour Energy Are Collaborating In Buried SMRs To Power Data Center

    Nuclear Reactors 1460 – Deep Fission And Endeavour Energy Are Collaborating In Buried SMRs To Power Data Center

         Offering a unique approach to powering data centers through nuclear fission energy, Deep Fission and Endeavour Energy have just announced a strategic partnership. Their collaboration plans to bury small modular reactors (SMRs) a mile underground.
         A Deep Fission in a press release said, “As part of the agreement, Endeavour and Deep Fission have committed to co-developing 2 gigawatts (GW) of nuclear energy to power Endeavour’s expanding global portfolio of Edged data centers.” Notably, the first reactors are expected to be operational by 2029.
         Deep Fission is a nuclear energy company that is pioneering this new approach. They have designed SMRs that are lowered into thirty-inch boreholes drilled a mile deep.
         This technique takes advantage of the natural geological properties at that depth. The earth supplies robust containment and constant pressure. This eliminates the need for huge concrete structures typically used for containment in aboveground nuclear reactors.
         This approach offers several important advantages. It significantly reduces the cost of construction and minimizes the environmental impact by decreasing the surface footprint of the nuclear power plant.
         Elizabeth Muller is Co-Founder and CEO of Deep Fission. She said, “Our technology not only ensures the highest levels of safety but also positions us to deliver zero-carbon continuous power at a cost of just 5-7 cents per kWh.”  In addition, it enhances safety by utilizing the natural geological features as a barrier.
         Endeavour Energy’s SMR, which it will be co-developing with Deep Fission, will be utilized to power its growing global network of Edged data centers.
         Jakob Carnemark is the Founder of Endeavour and Edged data centers. He said, “We are constantly searching for technologies capable of supporting the unprecedented demands of AI and meeting green energy goals, but they have to be economically viable. Deep Fission’s solution slashes the high costs and long timelines of surface-built nuclear projects. It enhances safety, and delivers clean, reliable energy with high power density of more than one hundred megawatts in a quarter acre.”
         There is significant momentum for getting power from nuclear reactors for data centers right now.
         In October of 2024, Google signed the world’s first corporate agreement with Kairos Power to buy electricity from multiple SMRs for its data centers. As per a blog post from Google, it plans to purchase a total of five hundred megawatts of power from six to seven reactors.
         OpenAI CEO Sam Altman-backed nuclear energy startup Oklo has just entered into a partnership to provide up to twelve gigawatts of energy to Switch, a leading AI provider and data center operator.
         This highlights the growing need for clean and reliable energy sources for data centers. These sources are crucial to cover the increasing energy demands of AI applications and other compute-intensive workloads.
         The latest innovative technology from Deep Fusion has the potential to reshape the energy landscape for a more sustainable future. It can provide a potentially safer and more cost-effective way to generate clean energy.
          The press release concludes that “The partnership between Deep Fission and Endeavour will redefine how clean energy is incorporated into electricity-demanding industries.”

  • Nuclear Reactors 1459 – Friends of The Earth Fight U.S. Grant Of One Billion Dollars To California For Diablo Canyon Nuclear Power Plant

    Nuclear Reactors 1459 – Friends of The Earth Fight U.S. Grant Of One Billion Dollars To California For Diablo Canyon Nuclear Power Plant

         The U.S. Department of Energy (DoE) plans to award one billion dollars in federal funding to keep Central California’s aging Diablo Canyon nuclear plant in operation. An environmental group’s lawsuit to stop the award appears to be on shaky grounds.
         U.S. District Judge George Wu was appointed by George W. Bush. At a hearing Thursday in downtown Los Angeles, he expressed reservations about Friends of the Earth’s (FoE) standing to pursue the case.
         He noted that no ruling he could issue would change the fact that California wants the plant. The nuclear facility provides nine percent of the state’s electricity. There’s currently not enough renewable energy to meet the state’s climate goals.
         PG&E owns and operates the nuclear plant. California has already loaned one billion four hundred million on the condition the company would seek federal grant money to repay the state. If Judge Wu were to agree with the antinuclear group that the DoE is violating National Environmental Policy Act through an outdated environmental analysis, California may very well forgive the loan.
         The judge asked the attorneys for FoE, “It the money from California has already come and gone, on what basis do the plaintiffs have standing? If California and PG&E want to go forward, your client has no say.”
         The judge did not issue a final decision on the government’s request to dismiss the FoE lawsuit. But he did order PG&E to provide him with a declaration about the state funding it has received and about the terms of the loan.
         Founded in 1969 in part to oppose the construction of the nuclear plant on California’s Central Coast, FoE argues that the DoE’s January decision to fund Diablo Canyon went beyond the facility’s previously anticipated shutdown dates of 2024 and 2025. The FoE said that the federal government ignored the fact that a fifty-year-old environmental analysis used for the decision didn’t consider risks beyond those expiration dates.
         Even in the best of times, all nuclear reactors carry a risk that an accident will lead to a potential catastrophic radiation release according to FoE.
         The FoE said in its complaint, “Diablo Canyon presents an even riskier case, given a significant lack of maintenance or upgrades at the facility, recent seismic discoveries in the area, and the plant’s use of an [sic] outdated cooling mechanisms.”
         The DoE asked the judge to dismiss the lawsuit, arguing the FoE lacks standing. It said there is no favorable ruling that could redress the FoE’s purported injuries from the federal government’s award of the grant.
         Maggie Woodward is an attorney for the government. She told the judge, “California will allow the plant to operate,” even if the federal funding is withdrawn, “The information that we have shows that they’re not intending to reverse course on this.”
         While the plant has exceeded its original forty-year operating licenses, PG&E claims that it’s continually upgraded and undergoes regular inspections by the U.S. Nuclear Regulatory Commission.
         The California legislature passed a bill into law in 2022 that directed PG&E to take all “necessary and prudent” measures to extend the nuclear plant’s operations. The plant provides about seventeen percent of the state’s zero-carbon electricity supply. Officials say they should keep the plant running for another five years beyond 2025 to improve statewide energy reliability as California transitions away from oil and gas.
