Westinghouse Electric Company has signed a service agreement with the Canadian Nuclear Safety Commission (CNSC) to bring the eVinci microreactor closer to commercialization, the company announced Tuesday. The agreement initiates a vendor design review (VDR)—a prelicensing technical assessment of a company’s reactor technology.

The objective of a VDR, according to the CNSC, is to verify the acceptability of a nuclear power plant design with respect to Canadian nuclear regulatory requirements and expectations, as well as Canadian codes and standards. The review also aims to identify fundamental barriers to licensing a new design in Canada and to assure that a resolution path exists for any design issues identified.

Ontario Power Generation and Microsoft Canada have formed a partnership aimed at combatting climate change and driving sustainable growth across the province of Ontario, the Canadian utility announced this week.

Under the partnership, Microsoft will procure clean energy credits (CECs) sourced from OPG’s nuclear and hydro assets in Ontario on an hourly basis. (OPG’s nuclear assets include the four-unit Darlington plant and six-unit Pickering facility.) According to the announcement, this will enable Microsoft to advance toward its 100/100/0 by 2030 goal, which commits the software firm to powering its data centers globally with zero-carbon energy, 24/7.

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.

Westinghouse Electric Company continues its aggressive campaign to become the large reactor supplier for Poland’s planned nuclear power facilities, recently signing memoranda of understanding with 22 firms in the Central European nation.

The American company, with its AP1000 design, is one of three suppliers vying to provide the units for the first Polish nuclear plant project, the other contenders being Électricité de France and Korea Hydro & Nuclear Power.

The MOUs were signed last week in the presence of U.S. ambassador to Poland Mark Brzezinski.

The Department of Energy announced up to $50 million for a new milestone-based fusion energy development program on September 22. The funding opportunity announcement is open to for-profit companies—possibly teamed with national laboratories, universities, and others—that are prepared to meet major technical and commercialization milestones leading to a pilot fusion power plant design.

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.)

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.

The Department of Energy announced September 13 that it would spend up to $10 million in a bid to settle the question of whether low-energy nuclear reactions (LENR)—historically known as “cold fusion”—could ever become a carbon-free energy source. The funding is part of an Advanced Research Projects Agency–Energy (ARPA-E) LENR Exploratory Topic designed to “encourage the submission of the most innovative and unconventional ideas in energy technology.”

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.

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.

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.

Examining Supply-Side Options to Achieve 100% Clean Electricity by 2035 was written by research staff at the National Renewable Energy Laboratory, so its reliance on solar and wind energy to decarbonize the grid by 2035 is not surprising. But that’s a big ask for any variable energy technology, especially if the nation’s largest source of clean power—nuclear energy—is relegated to a supporting role. Massive additions of solar and wind energy on the order of 2 TW would require a supporting infrastructure of new transmission lines, as well as batteries and hydrogen for daily and seasonal energy storage that would drive demand and capacity requirements higher.

The Hanford tanks, on which building began in 1943, were never supposed to hold waste for many decades. If grouting and disposal had occurred according to plans from the 1980s, this waste would already be in the ground and we would have saved almost $100 billion. (Photo: DOE)

At the end of June, a federal judge approved, with the agreement of the Washington State Department of Ecology, a request to push back the deadline 20 months for beginning nuclear waste treatment at the $17 billion Waste Treatment and Immobilization (Vit) Plant at the Hanford Site because of pandemic-related delays. The Direct-Feed Low-Activity Waste program is the Department of Energy’s plan to start treating low-level radioactive waste first at the Vit Plant and then start treating high-level radioactive waste sometime in the 2030s.

This is the fifth delay granted by the court for the project, which should have begun operations in 2007. In one sense, this delay is good, since turning LLW into glass through vitrification is about as smart as singing into the wind. The chemistry of this waste makes it much better suited to grouting, a treatment used by everyone else in the United States and the world.

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.
