Unit 3 at the Doel nuclear power plant has become Belgium’s first reactor to be permanently shuttered, in keeping with that nation’s nuclear phaseout policy. The 1,006-MWe pressurized water reactor, which began commercial operation in October 1982, was removed from service last Friday at 9:31 p.m. (local time).
Belgium’s nuclear reactor fleet now consists of six operating units: Doel-1, -2, and -4 and Tihange-1, -2, and -3. Next on the retirement list is Tihange-2, scheduled to be shut down in February 2023.

Moving forward with its plan for small modular reactor deployment in Estonia, Fermi Energia has issued tenders to three SMR firms—GE Hitachi (GEH), NuScale Power, and Rolls-Royce, developers of the BWRX-300, NuScale Power Module, and Rolls-Royce SMR, respectively.

As part of its planning and regulatory activities to potentially build small modular reactors (SMRs) in currently nuclear-powerless Saskatchewan, Canadian utility SaskPower has selected the province’s Estevan and Elbow regions for further study. (In 2018, SaskPower joined the Canadian government, three other provinces, and four other Canadian utilities to participate in the development of A Call to Action: A Canadian Roadmap for Small Modular Reactors.)

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.)
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.

In an essay titled “How the Fed will Strangle New Nukes,” published this week by American Thinker, nuclear engineer and writer Joseph Somsel warns that despite current expectations of a nuclear construction boom, “As in the late 1970s, rising interest rates will put the kibosh on new nukes.” Somsel therefore urges the financing and building of new nuclear facilities right now, before ongoing inflation and increasingly high interest rates “kill a lot of the plans” for new nuclear power plants.
