Power & Operations

Forty years ago, Nuclear News published an analysis of U.S. nuclear plant operations over the three years that followed the Three Mile Island-2 accident in 1979, scrutinizing capacity factors as a measure of how well a reactor was performing compared to its potential. The purpose: “To call attention to the units that have had the best results, and to explore the question: What have the personnel at these top units been doing right?”

The Department of Energy’s Office of Nuclear Energy released an updated version of its consent-based siting process on April 25. The DOE will use the process to engage with willing communities to site one or more consolidated interim storage facilities for commercial spent nuclear fuel, reducing the number of locations where spent fuel is stored and easing the burden on U.S. taxpayers.

The Korea Atomic Energy Research Institute (KAERI) and the government of Alberta have agreed on a comprehensive cooperation framework to explore the viability of using small modular reactors to help decarbonize the province—Canada’s biggest energy producer and its biggest polluter. The announcement comes the same week that Alberta’s United Conservative Party government released a climate plan aimed at reaching net zero by 2050.

The Canadian Nuclear Safety Commission (CNSC) has completed phase two of its prelicensing vendor design review for Terrestrial Energy’s Integral Molten Salt Reactor (IMSR), the Ontario-based advanced nuclear technology firm announced Tuesday. Phase one of the VDR commenced in April 2016 and was completed in November of the following year.

The recent shutdown of Germany’s three remaining nuclear reactors is “a senseless act of folly, against all the science and available evidence.” So writes Lincoln Hill, director of policy and external affairs at the Nuclear Industry Association, in a strong opinion piece on CapX, a publication of the London-based Centre for Policy Studies.

Illogical: Hill is emphatic is criticizing Germany’s move as an antiscience action that is ideologically driven and harmful to the cause of battling climate change. He calls it “the single worst decision Europe has taken in the fight against climate change, and one for which we all are paying the price.”

He points out that Germany’s former chancellor, Angela Merkel, “ostensibly” made the decision to phase out nuclear energy as a reaction to the Fukushima accident in Japan. However, Japan itself is seeking to “restart its 30-GW nuclear fleet, even as Germany finishes shuttering a fleet of 20 GW.”

Germany may have walked away from nuclear energy, but just across the border, Poland continues to stride confidently toward it.

After solidifying plans in February for deploying Westinghouse’s AP1000 reactors in Poland, Polskie Elektrownie Jądrowe (PEJ) on April 13 submitted an application to the Ministry of Climate and Environment for a decision-in-principle regarding the nation’s initial nuclear project—construction of an AP1000 plant at a site some 40 miles northwest of Gdansk, the capital of Poland’s Pomeranian province.

Although the first quarter of the year saw some of the French nuclear fleet return to service, it was not at the rate originally anticipated, according to data analysis company EnAppSys. France’s nuclear availability, the company noted, was expected to reach a maximum of 50 GW by the middle of the first quarter, but that goal was not reached due to several reasons, including the need for additional repairs and maintenance when stress corrosion cracking first appeared in several reactors last year. Workforce strikes at nuclear operator Électricité de France also led to widespread employee walkouts from nuclear power plants.

G7 governments should support life extension for today’s power reactor fleet, restart operable units, and accelerate the deployment of advanced reactors, states a joint declaration issued April 16 at the Nuclear Energy Forum, a first-of-its-kind colloquy held on the margins of the G7 Ministers’ Meeting on Climate, Energy and Environment in Sapporo, Japan.

Ignoring a last-minute plea from a long list of scientific luminaries (including Nobel laureate Steven Chu and climate scientist James Hansen) to reconsider, as well as recent polls showing pronuclear sentiment among a majority of its population, Germany shut down its last three operating nuclear power plants late Saturday, ending 60-plus years of electricity generation from fission. (Germany’s first nuclear power plant, Kahl, was commissioned in 1961 and closed in 1985.)

The Palisades nuclear power plant may have entered retirement, but it’s not dead yet. Plant owner Holtec International is continuing with its unprecedented effort to restart the Covert, Mich., single-unit facility, shuttered 11 months ago by previous owner Entergy.

The Department of Energy last week announced up to $450 million in funding from the Bipartisan Infrastructure Law to advance clean energy demonstration projects at current and former mine sites. The law, officially the Infrastructure Investment and Jobs Act, was signed by President Biden in November 2021.

Portland, Ore.–based PacifiCorp—owner of the soon-to-be-retired Wyoming coal plant selected in 2021 as the future site of TerraPower’s Natrium reactor demonstration project—has released its 2023 Integrated Resource Plan, which recommends the addition of two more Natrium units to the company’s generation resource mix by 2033.

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.
