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.

The Nuclear Regulatory Commission will discuss the Davis-Besse nuclear power plant safety performance last year in a public meeting this Thursday, August 29.

The Nuclear Regulatory Commission has renewed the operating licenses of Comanche Peak Units 1 and 2 for an additional 20 years.

Unit 1’s operating license now expires on February 8, 2050, and Unit 2’s on February 2, 2053.

Investor’s Business Daily reported May 10 that the first-quarter earnings of Constellation Energy, the largest operator of nuclear power plants in the United States, surged 858 percent to reach a share price of $2.78, partly as a result of promising expectations regarding demand for artificial intelligence data centers. The S&P 500 stock value of Constellation jumped 3.7 percent on May 8 to $208.

Vistra this week completed its acquisition of Energy Harbor Corp., a move the company announced almost exactly a year ago with a $3.43 billion price tag.

Another calendar year has passed. Before heading too far into 2024, let’s look back at what happened in 2023 in the nuclear community. In today's post, compiled from Nuclear News and Nuclear Newswire are what we feel are the top nuclear news stories from January through March 2023.

Stay tuned for the top stories from the rest of the past year.

The Nuclear Regulatory Commission has approved the transfer of the operating licenses for four reactors and their associated spent fuel storage facilities from Energy Harbor Nuclear Corporation to Vistra Operations Company, the agency announced September 29.

In a filing Monday with the Federal Energy Regulatory Commission, Vistra Corporation committed to divesting itself of two power generation assets to help alleviate concerns over its proposed acquisition of Energy Harbor.

The Department Justice earlier this week filed comments with the Federal Energy Regulatory Commission regarding Vistra Corporation’s proposed acquisition of Energy Harbor, the Ohio-based owner and operator of the Beaver Valley, Davis-Besse, and Perry nuclear plants. Echoing misgivings raised in June by PJM Interconnection’s market monitor Monitoring Analytics regarding the possible exercise of undue market power as a result of the deal, the DOJ Antitrust Division’s 16-page document urges FERC to carefully review the proposal to ensure it will not substantially lessen competition and increase wholesale electricity prices in the PJM region.

Energy Harbor has filed its initial license renewal application for the Perry nuclear power plant, requesting an additional 20 years of operation for the facility, the Nuclear Regulatory Commission announced yesterday. Dated July 3, the 2,427-page application is now available on the agency’s website.

The Nuclear Energy Institute—along with Constellation, Energy Harbor, PSEG, and Vistra—submitted a 19-page letter on May 24 to the Treasury Department and Internal Revenue Service, taking issue with April 10 comments to those agencies from the Clean Air Task Force (CATF) and Natural Resources Defense Council (NRDC) concerning the Inflation Reduction Act’s clean hydrogen production tax credit (Internal Revenue Code sec. 45V). (The Treasury and the IRS released a notice last November requesting public input on the credit’s implementation.)

Texas-based Vistra Corporation, owner of the Comanche Peak nuclear plant, has announced a $3.43 billion deal to acquire Energy Harbor, the Ohio-based owner and operator of the Beaver Valley, Davis-Besse, and Perry nuclear facilities.

The Nuclear Regulatory Commission has docketed Vistra Corporation’s license renewal application for the Comanche Peak reactors.

Operated by Vistra subsidiary Luminant and located in Glen Rose, Texas, the Comanche Peak plant is home to two pressurized water reactors. The original 40-year licenses for Units 1 and 2 expire in February 2030 and February 2033, respectively.

Vistra Corporation announced yesterday that it is seeking 20-year life extensions for its Comanche Peak reactors and has submitted an application for license renewals to the Nuclear Regulatory Commission.

Operated by Vistra subsidiary Luminant and located in Glen Rose, Texas, Comanche Peak is home to two Westinghouse-supplied pressurized water reactors. The 1,218-MWe Unit 1 began commercial operation in August 1990, with the 1,207-MWe Unit 2 joining in August 1993. The original 40-year licenses for Units 1 and 2 expire in February 2030 and February 2033, respectively.
