Nuclear technology firm TerraPower and utility partner PacifiCorp have launched a study to evaluate the feasibility of deploying up to five additional Natrium reactor and integrated energy storage systems in the utility’s service territory by 2035, the companies announced yesterday. (PacifiCorp’s business units—Pacific Power and Rocky Mountain Power—serve customers in California, Oregon, and Washington, and in Idaho, Utah, and Wyoming, respectively.)

Canada’s Ontario Power Generation (OPG) and Czech Republic–based ČEZ have agreed to collaborate on nuclear technology deployment, including small modular reactors, under a memorandum of understanding signed yesterday in Prague.

Ontario’s largest electricity generator and the European energy giant have both pledged to achieve net-zero carbon emissions by 2040.

The United Kingdom’s Nuclear Decommissioning Authority (NDA) has announced the signing of a memorandum of understanding with Cwmni Egino to support the development of a small-scale nuclear project in North Wales.

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.

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.

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.)

U.S. nuclear technology company TerraPower announced yesterday the close of a $750 million equity raise—one of the largest advanced-nuclear investment drives to date, according to the announcement—with $250 million of that contributed by South Korean firms SK Inc. and SK Innovation.

Both firms are subsidiaries of the Seoul-based conglomerate SK Group, South Korea’s second-largest conglomerate, after Samsung Group.

After hours of debate alternating between Democratic praise for the Inflation Reduction Act (IRA) and Republican denunciation of it, the House of Representatives late Friday passed the sweeping energy, tax, and health care package in a straight party-line vote, 220–207. Its passage represents a significant win for President Biden, who is expected to sign the bill into law this week.

The boldly named $430 billion measure includes $369 billion in energy security and climate spending, with nuclear energy included among the beneficiaries.

Evidence that Canada is serious about becoming a world leader in small modular reactor deployment continues to mount. Ontario-based SMR developer Terrestrial Energy yesterday inked a memorandum of understanding with Invest Alberta—a crown corporation of the government of Alberta that promotes the province internationally—to support commercialization of the company’s Integral Molten Salt Reactor (IMSR) in western Canada.

Romania’s Nuclearelectrica, the state-owned operator of the two-unit Cernavoda nuclear power plant, has awarded Candu Energy a contract to conduct design and engineering services for the facility’s Unit 1 refurbishment project, according to an announcement last week from SNC-Lavalin, Candu Energy’s parent company.

The Department of Energy earlier this year approved part one of a loan application from Holtec International for small modular reactor construction and invited the firm to apply for a loan to help build four of its SMR-160 units and grow its manufacturing capacity to produce the first wave of SMRs.

The U.K. government has granted a development consent order (DCO) for EDF Energy’s proposed Sizewell C plant near Leiston in Suffolk, moving the new nuclear build project closer to a reality.

Nuclear New Build (NBB) Generation Company, an EDF Energy subsidiary, submitted the DCO application to the government’s Planning Inspectorate in May 2020, setting out the range of measures the project would implement to mitigate construction effects and maximize community benefits. The Planning Inspectorate accepted the application in June 2020 and completed its examination in October 2021. Recommendations were made to the secretary of state for business, energy, and industrial strategy this February.

Ontario Power Generation has updated its Green Bond Framework to include nuclear energy in recognition of the role the technology stands to play in helping the company reach its decarbonization goals. (OPG’s climate change plan, established in 2020, commits the firm to achieving net-zero carbon emission status by 2040.)

The green bonds issued by the utility and its subsidiaries are used to finance and/or refinance certain energy projects and support the development of clean technologies.

As part of its strategy to achieve net-zero status by 2050, the Tennessee Valley Authority yesterday issued a request for proposals for supplying up to 5 GW of carbon-free energy that must be operational before 2029.

In a much-anticipated vote yesterday, EU lawmakers voted down a resolution objecting to the European Commission’s proposal to add nuclear energy and natural gas to the list of green technologies covered by the EU taxonomy—the classification system used by the European Union to steer private investment toward environmentally sustainable economic projects.

The vote, held during the European Parliament’s July 4–7 plenary session, was 328 opposed to the resolution, 278 in favor, and 33 abstaining. An absolute majority—353 members—was required for the resolution to be passed and the proposal vetoed.

On the road to achieving net-zero by midcentury, low- or no-carbon energy sources that slash carbon dioxide emissions are critical weapons. Nevertheless, the role of nuclear energy—the single largest source of carbon-free electricity—remains uncertain.

Nuclear energy, which provides 20 percent of the electricity in the United States, has been a constant, reliable, carbon-free source for nearly 50 years. But our fleet of nuclear reactors is aging, with more than half of the 92 operating reactors across 29 states at or over 40 years old—the length of the original operating licenses issued to the power plants. While some reactors have been retired prematurely, there are two options for those that remain: retire them or renew their license.

The United Arab Emirates’ Federal Authority for Nuclear Regulation (FANR) has issued the operating license for the Barakah nuclear plant’s Unit 3 reactor, the Emirates Nuclear Energy Corporation announced yesterday. In addition, following receipt of the license, ENEC subsidiary Nawah Energy Company began the process of loading fuel assemblies into the unit, according to the announcement.

The Maryland Energy Administration (MEA) has awarded grants to Rockville, Md.–based X-energy—developer of the Xe-100 small modular reactor—and Frostburg State University for a collaborative study to determine the potential for siting an SMR at a state coal site. A joint analysis of the study’s findings is to be delivered to MEA later this year.

French utility giant EDF has announced that its NUWARD small modular reactor design will be the case study for a European early joint regulatory review led by the French Nuclear Safety Authority (ASN). Also participating in the review process will be the Czech Republic’s State Office for Nuclear Safety (SUJB) and Finland’s Radiation and Nuclear Safety Authority (STUK).
