Power & Operations

The United Kingdom’s nuclear regulators—the Office for Nuclear Regulation (ONR), the Environment Agency, and Natural Resources Wales (NRW)—have announced the completion of step one of their generic design assessment (GDA) for Rolls-Royce SMR’s 470-MWe small modular reactor design and the start of step two, which is expected to last 16 months.

Canada’s Bruce Power, operator of Ontario’s eight-unit Bruce nuclear power plant, has announced the issuance of C$600 million (about $446.3 million) in green bonds in support of the company’s net-zero-by-2027 goal. (Investopedia defines green bonds as fixed-income instruments specifically earmarked to raise money for environmentally friendly projects.)

Unit 3 at the Vogtle nuclear power plant has been successfully synchronized and connected to the electric grid, Georgia Power announced on April 1. The unit—one of two Westinghouse-supplied AP1000s at the Waynesboro, Ga., plant’s nuclear expansion site—becomes the first new U.S. power reactor to start up in seven years.

DOWNERS GROVE, ILL – The American Nuclear Society (ANS) CEO and Executive Director Craig Piercy issued the following statement on the connection of Vogtle unit 3 to the grid:

The Department of Energy released Pathways to Commercial Liftoff: Advanced Nuclear earlier this month. It is one of the first in a series of reports on clean energy technologies and the private and public investments needed to overcome hurdles to full-scale deployment. The report makes a clear case for investment in nuclear power and challenges potential investors and operators to move beyond the current “wait and see” stalemate and generate “a committed orderbook . . . for 5–10 deployments of at least one reactor design by 2025.”

Nuclearelectrica has signed a memorandum of understanding with Emirates Nuclear Energy Corporation (ENEC) to provide both parties with an enabling framework for potential collaboration on the development and expansion of nuclear energy programs in Romania and the United Arab Emirates, as well as in Central and Eastern Europe.

The challenges of climate change are bringing nuclear energy back into focus. Even in Germany, which decided on a general nuclear phaseout in 2011 as a response to the Fukushima disaster that year, nuclear energy is again being discussed as a bridging technology. Compared with fossil fuels, nuclear saves considerable greenhouse gases. However, for a holistic view of CO₂ emissions from power plants, the procurement, maintenance, and repair of plant components must also be considered. At the very least, the CO₂ emissions caused by the high costs of testing and maintaining a nuclear power plant can be reduced.

Startup company Last Energy has announced power purchase agreements for 34 units of its 20-MWe nuclear power plants with four industrial partners in Poland and the United Kingdom. In total, according to the company, the deals represent more than $18.9 billion in electricity sales.

The Nuclear Regulatory Commission recently announced that it will begin reviewing most of the standard design approval (SDA) application for NuScale Power’s uprated small modular reactor technology, with the remainder of the review on hold until the company provides additional details on a key safety topic.

A recurring leak of water containing tritium has led to the temporary shutdown of Xcel Energy's Monticello nuclear power plant, in Minnesota.

“While the leak continues to pose no risk to the public or the environment, we determined the best course of action is to power down the plant and perform the permanent repairs immediately,” said Chris Clark, president of Xcel Energy–Minnesota, North Dakota, and South Dakota, in a March 23 news release. “We are continuing to work with and inform our state, federal, city, and county leaders in the process.”

Powering down the reactor to shutdown condition started last Friday.

The development of human society and technology is closely correlated to the means of energy acquisition, utilization method, efficiency, and spectrum of applications. High quality of life and sustainable socioeconomic development require a sustainable and reliable energy supply. Wealth, health, food, water, infrastructure, education, and even life expectancy itself strongly correlate with the consumption of energy per capita. Having an adequate, reliable, affordable, eco-friendly, and sustainable supply of energy is becoming more crucial for economic development and improving human well-being.

The Nuclear Regulatory Commission will hold four hybrid meetings around the United States as it seeks comment on a proposed rule to update its license renewal generic environmental impact statement (GEIS).

“I’m glad you came to our party!” said GE Hitachi Nuclear Energy (GEH) chief nuclear officer Nicole Holmes as she prepared to announce that Wilmington, N.C.–based GEH will develop a standard design for its BWRX-300 boiling water small modular reactor with not one but three power producers representing three countries: Tennessee Valley Authority (TVA), Ontario Power Generation (OPG), and Synthos Green Energy (SGE). Celebration was a theme throughout the March 23 event held in Washington, D.C., which was flush with dignitaries representing the United States, Canada, and Poland.

According to a new study conducted by the economics consulting firm Analysis Group, “Massachusetts utilities could save their customers $880 million to more than $2 billion by 2032 by entering into a long-term power purchase contract with the Seabrook Station nuclear plant.” The study, Economic and Environmental Benefits to Massachusetts from the Operation of the Seabrook Nuclear Plant, also found that operation of the plant through 2032 is expected to contribute as much as $2.9 billion to the state’s economy and reduce regional greenhouse gas emissions by 5 million tons per year.

Hunt

In his spring 2023 budget speech to the House of Commons last Wednesday, U.K. chancellor of the exchequer Jeremy Hunt confirmed that, subject to consultation, nuclear power will be classified as environmentally sustainable in the U.K. green taxonomy, providing potential private investors in nuclear projects access to the same incentives currently enjoyed by investors in renewables. (Last year, the European Union added nuclear and natural gas to the list of green technologies covered by its taxonomy, but only on a transitional basis under what the European Commission termed “clear and strict conditions.”)

“We have increased the proportion of electricity generated from renewables from under 10 percent to nearly 40 percent,” Hunt declared. “But because the wind doesn’t always blow and the sun doesn’t always shine, we will need another critical source of cheap and reliable energy. And that is nuclear.”

Tsai

The antinuclear energy policies of Taiwanese president Ing-wen Tsai, of Taiwan’s republic’s Democratic Progressive Party, stoked controversy on March 14 when the nation’s Kuosheng-2 nuclear power plant was taken off line to be decommissioned. Minister of economic affairs Mei-hua Wang, who oversees the state-run Taiwan Power Company (Taipower), claimed that the shutdown will not affect power supply because it will be offset by hydroelectric power, as well as gas- and coal-fired power plants. However, objectors to the shutdown claim the possibility of electricity blackouts, with opposition legislator I-ding Wu, of the Kuomintang (Chinese Nationalist) Party, countering that renewable energy would be insufficient to meet Taiwan’s energy needs and that fossil fuels are “dirtier” and “more expensive.”

Nuclear-free homeland: Tsai came to office in 2016, promising to make Taiwan a “nuclear-free homeland” by 2025 by decommissioning all six of its operable nuclear reactors when their 40-year operating licenses expired.

GE Hitachi Nuclear Energy’s (GEH’s) BWRX-300 technology has completed phases 1 and 2 of the Canadian Nuclear Safety Commission’s vendor design review (VDR) process, the Wilmington, N.C.–based company announced yesterday.

EDF Energy, owner and operator of the United Kingdom’s nuclear reactor fleet, announced last week that it intends to keep its Hartlepool and Heysham 1 stations in operation to March 2026—two years past their previously scheduled 2024 retirement dates. EDF added that an additional 12 months of operation beyond 2026 is being contemplated.

NuScale Power, the Portland, Ore.–based small modular reactor developer, announced last week that it has placed the first upper reactor pressure vessel (RPV) long-lead material (LLM) production order with South Korea’s Doosan Enerbility.

Proponents of Diablo Canyon nuclear power plant received the heartening news on March 2 that the Nuclear Regulatory Commission had granted a “timely renewal” exemption to allow the plant to continue operating while its new license renewal application was under review. The exemption came after the NRC denied in January plant owner Pacific Gas & Electric’s request for the agency to resume review of its original license renewal application.
