Released this week in the lead-up to November’s COP27 event in Egypt is a report from the United Nations Economic Commission for Europe, Carbon Neutrality in the UNECE Region: Technology Interplay under the Carbon Neutrality Concept, which calls for maximizing the use of all low- and zero-carbon technologies—including nuclear technology—to achieve net-zero carbon emissions by 2050.

Termed by the UNECE a “roadmap to carbon neutrality for Europe, North America, and Central Asia,” the 60-page report finds that to attain the net-zero goal, investment in energy as a percentage of gross domestic product needs to grow from 1.24 percent in 2020 to 2.05 percent every year from 2025 until 2050—translating to between $44.8 trillion and $47.3 trillion by 2050, with any additional delay in taking action adding to that price tag.

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.

As the largest ultra-low-carbon electricity source in the United States, nuclear energy is a vital pillar of the effort to mitigate climate change. Deployment of advanced nuclear reactor and fuel technologies has been identified as a unique challenge in the production of new nuclear power plants to help maintain and grow our nuclear generating capacity. The licensing of novel nuclear reactor technologies also continues to be a facet of the broader challenge of advanced reactor deployment. When it comes to non–light water reactors and Generation III+ light water reactors, such as the AP-1000 or EPR, deployment is “2X over budget and behind schedule.”¹ However, in the case of recent large Generation III+ light water reactors, licensing has not been the rate-limiting step in the reactor deployment timeline, nor has it had a first-order impact on cost. With that said, several significant advances have been made in the expedition of licensing. This article focuses on three areas where progress has been made since this grand challenge was formulated in 2017, with highlights of some examples where the American Nuclear Society has guided or supported this progress.

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.)

Curtiss-Wright Corporation and small modular reactor developer X-energy have announced the signing of a preferred strategic supplier agreement to advance the design and deployment of the latter’s Xe-100 SMR.

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.

Paragon Energy Solutions and Reuter-Stokes have signed a contract to design and manufacture neutron monitoring detectors for small modular reactor developer NuScale Power.

U.S. utility Constellation Energy has signed a memorandum of understanding with ULC-Energy, an Amsterdam-based nuclear development company, to support deployment of a fleet of Rolls-Royce small modular reactors in the Netherlands.

Advanced reactor developers are designing many new nuclear energy products, targeting commercial demonstration before 2030. These products aim to provide different products and grid services beyond what is provided by the first generations of commercial nuclear plants, namely, gigawatt-scale electricity production. These reactors are intended for deployment in many novel scenarios, including being closer to population centers. They will be sited in governmental processes that encourage far more public participation than was possible when many of the existing plants were sited and built in the 1960s and 1970s. This means that community engagement and approval likely will be critical for project success. This article, which discusses this issue of social license, is an adaptation of “Social license in the deployment of advanced nuclear technology,” published in Energies in 2021.¹ A more detailed discussion can be found in the original article.

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.

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.

The Nuclear Regulatory Commission last Friday announced the publication of its ninth report to the Convention on Nuclear Safety, describing the federal government’s actions under the convention to achieve and maintain safety for the nation’s nuclear power reactor fleet.

An International Atomic Energy Agency treaty, the Convention on Nuclear Safety was adopted in 1994 and entered into force in 1996. In 1999, it was ratified by the U.S. Senate.

The aim of the convention, according to the IAEA, is to “commit contracting parties operating land-based civil nuclear power plants to maintain a high level of safety by establishing fundamental safety principles to which states would subscribe.” Signatories are required to submit reports for peer review at meetings held every three years.

Who better to talk with about the licensing of nuclear facilities and materials than Christopher T. Hanson, the chairman of the five-member Nuclear Regulatory Commission? Hanson is the principal executive officer of and official spokesman for the NRC. As a collegial body, the Commission formulates policies, develops regulations governing nuclear reactor and nuclear material safety, issues orders to licensees, and adjudicates legal matters.

At this writing, the situation at Ukraine’s Zaporizhzhia nuclear power plant is as fraught with tension as ever, despite an International Atomic Energy Agency support and assistance mission to the site last week led by director general Rafael Mariano Grossi.

Just one week after entering into an exclusive agreement with a Dutch nuclear development company to deploy small modular reactors in the Netherlands, U.K.-based Rolls-Royce SMR has announced the signing of a memorandum of understanding with Škoda JS to explore “areas of collaboration” for SMR deployment in both the Czech Republic and elsewhere in Central Europe.

Southern Nuclear, operator of the two-unit Hatch nuclear plant, announced yesterday that it will seek subsequent license renewals (SLR) for both reactors.
