Dominion Energy’s V.C. Summer nuclear power plant, in Jenkinsville, S.C., has been authorized to operate for 80 years, until August 2062, following the renewal of its operating license by the Nuclear Regulatory Commission for a second time.

Texas Tech University and Fermi America shared plans on June 26 to build “the world’s largest advanced energy and artificial intelligence campus” in Amarillo, Texas, near the Pantex nuclear weapons plant. Fermi America is a company cofounded by former Texas governor and energy secretary Rick Perry and his son, Griffin Perry, a cofounder and past senior advisor at Grey Rock Investment Partners. The announcement—a first press release from relative newcomer Fermi America—says the company “proudly answers President Donald J. Trump’s call to deliver global energy and AI dominance.”

The Nuclear Regulatory Commission is providing the opportunity to request a hearing on Dow Chemical Company’s application to construct a 320-MWe nuclear power plant at the company’s Seadrift site in Calhoun, Texas. Long Mott Energy, a wholly owned subsidiary of Dow Chemical, submitted its construction permit application to the NRC in March. It was accepted for review by the agency on May 12.

The Nuclear Regulatory Commission is conducting a special inspection at Constellation’s Quad Cities nuclear plant to review two events caused by battery issues. Neither event had any impact on public health or plant workers.

Santee Cooper is satisfied with the response generated by its initial request for proposals to buy what remains of the Summer-2 and -3 nuclear power plant project in South Carolina. The RFP was issued in January and the application window closed May 5.

Here’s a look at some recent announcements from the Nuclear Regulatory Commission.
Summer SLR: The NRC this month published its final environmental impact statement for Summer Unit 1’s subsequent license renewal application. Dubbed a supplemental EIS, the report is an important step in determining if Dominion Energy can continue operating its 966-MWe Westinghouse pressurized water reactor unit for an additional 20 years beyond August 6, 2042, the current end of its license.

Recent testing of a monitoring well in Minnesota near the Mississippi River detected tritium levels just below the safety standards set by the Environmental Protection Agency, Xcel Energy reported this week.

The Nuclear Regulatory Commission staff has concluded—with an assist from a Department of Energy environmental assessment released in February—that no environmental impact statement is needed for an exemption request from TerraPower that would allow the company to begin construction of the energy island of its planned Natrium sodium fast reactor in Kemmerer, Wyo. The NRC’s EA and finding of no significant impact (EA/FONSI), published on May 7, could clear the way for significant construction to begin while the NRC continues to review TerraPower’s construction permit application.

Ontario Power Generation GE Vernova Hitachi Nuclear Energy announced May 8 that Ontario authorities have approved construction plans for the first of four BWRX-300 small modular reactors at the Darlington New Nuclear Project site on Lake Ontario, less than 50 miles east of Toronto, Canada. The first new nuclear construction project in Ontario in more than three decades is also the first SMR construction project in North America.
Fig. 1. Median capacity factor of all reactors. The median DER net capacity factor of the 92 reactors included in this survey for the three-year period 2022–2024 is 90.96 percent. The 92 reactors in this survey are being compared with 94 reactors in 2019–2021 (when Indian Point-3 and Palisades were also included); 98 in 2016–2018; 99 in 2013–2015. There were 104 reactors in the five three-year periods prior to that. There were 53 reactors in the database in 1980–1982, and in the five subsequent periods there were 60, 77, 97, 102, and 103.
Nuclear generation has inertia. Massive spinning turbines keep electricity flowing during grid disturbances. But nuclear generation also has a kind of inertia that isn’t governed by the laws of motion.
Starting—and then finishing—a power reactor construction project requires significant upfront effort and money, but once built a reactor can run for decades. Capacity factors of U.S. reactors have remained near 90 percent since the turn of the century, but it took more than a decade of improvements to reach that steady state. The payoff for nuclear investments is long-term and reliable.
