Some eight months after the Nuclear Regulatory Commission denied Oklo Inc.’s license application to build and operate its Aurora microreactor in Idaho, the company has returned to the regulatory fray. On Wednesday, Oklo announced that it has submitted to the NRC a licensing project plan (LPP) outlining its proposed engagement to support future Aurora licensing activities.

Clean energy technology firm Bloom Energy has announced plans to install a 240-kW electrolyzer at Xcel Energy’s Prairie Island plant in Red Wing, Minn., to demonstrate the benefits of producing hydrogen with nuclear power. (One of Xcel’s two nuclear plants, Prairie Island houses twin 550-MWe pressurized water reactors.)

Scientists at Lawrence Livermore National Laboratory and Oregon State University (OSU) have developed a promising new method to isolate and study some of the rarest elements on Earth. Focused first on curium, they have identified three new complexes containing curium ions and revealed the molecules’ 3D structures, as well as previously unknown features.
How Kairos Power is applying rapid iterative development to the licensing process as part of its strategy to deliver on cost

Developing a first-of-a-kind reactor is a daunting endeavor. To be successful, advanced reactor designers need to achieve cost certainty by delivering a safe and affordable product at the promised cost. To meet this goal, Kairos Power structured its approach around four key strategies: 1) achieving technology certainty through a rapid iterative approach; 2) achieving construction certainty by demonstrating the ability to build it; 3) achieving licensing certainty by proving Kairos can license it; and 4) achieving supply chain certainty by vertically integrating critical capabilities. By mitigating risk in these four key areas, Kairos Power is confident that it will get true cost certainty for our future products.
The third prong in Kairos’s strategy—achieving licensing certainty—was a key driver in the decision to build the Hermes low-power demonstration reactor, and it remains a major workstream as the company’s construction permit application (CPA) undergoes review by the U.S. Nuclear Regulatory Commission. Licensing a new nuclear technology is no small challenge, and there are multiple approaches companies can take. Here’s a look at how we at Kairos are approaching it.

The Zaporizhzhia nuclear power plant.
The International Atomic Energy Agency’s board of governors has adopted a resolution calling for an immediate end to the Russian occupation of Ukraine’s Zaporizhzhia nuclear power plant. According to a report from Reuters, the 35-member board voted 26–2 yesterday in favor of the resolution, with seven abstentions. The two “no” votes were cast, unsurprisingly, by Russia and China, while abstentions came from Burundi, Egypt, India, Pakistan, Senegal, South Africa, and Vietnam.

Portland, Ore.–based NuScale Power and KGHM Polska Miedź S.A. have signed the first task order and a statement of commencement to begin work under an agreement signed in February to initiate deployment in Poland of NuScale’s small modular reactor technology, the American firm announced this week. The task order was inked September 7 at the 31st Economic Forum, held September 6–8 in Karpacz, Poland.

The Nuclear Regulatory Commission is increasing its oversight of the Waterford Steam Electric Station’s Unit 3 reactor due to a decade-long miscalibration of a radiation monitor.
In a September 13 letter to Entergy Operations, the NRC classified the issue at the Killona, La., facility as a “white finding”—agency parlance for a problem of low to moderate safety significance. (The NRC’s Reactor Oversight Process uses color-coded inspection findings and indicators to measure plant performance, starting at green and increasing to white, yellow, and red, commensurate with the safety significance of the issues involved.)

Nuclear power generation surpassed coal generation in the United States for the first time in 2020. As utilities continue to retire coal-fired plants, reusing the shuttered sites to host nuclear reactors could help the nation reach the goal of net-zero emissions by 2050 and prove economically beneficial both for nuclear deployments and for the communities impacted by fossil fuel generation. That’s according to a Department of Energy report released this week, detailing how hundreds of U.S. coal power plant sites that have recently retired or plan to close within the decade could be suitable for new nuclear power plants. Nuclear power’s high capacity factors mean those plants could deliver an added benefit—delivering more baseload power to the grid from the nameplate capacity replacement.

The Nuclear Regulatory Commission yesterday announced that it has issued a renewed license for Westinghouse Electric Company’s Columbia Fuel Fabrication Facility (CFFF), authorizing operations at the plant for another 40 years—through September 12, 2062.
Located in Hopkins, S.C., the CFFF manufactures fuel rods for use in commercial nuclear reactors. According to Westinghouse, 10 percent of the nation’s electricity comes from the fuel manufactured at the facility.

Scientists in the Departments of Radiation Oncology and Medicine at the University of Washington (UW) and Fred Hutchinson Cancer Center (Fred Hutch) are directly targeting cancerous cells traveling through patients’ bloodstreams with diseases such as leukemia and lymphoma using an intravenous injection of the radioactive isotope astatine-211 (At-211). The work, its challenges, and its promise were described in a recent news release from the National Isotope Development Center (NIDC), which is managed by the Department of Energy’s Isotope Program.

Maybe hold off commenting on those Palisades decommissioning plans for now: Michigan Gov. Gretchen Whitmer last Friday penned a letter to energy secretary Jennifer Granholm pledging state support for a Holtec International plan to restart the recently shuttered Palisades nuclear plant in Covert, Mich. It was Whitmer’s second letter to the Department of Energy head expressing support for Palisades and touting its value to the state.
