X-energy Commences First Irradiation Tests of Advanced TRISO-X Nuclear Fuel at Idaho National Laboratory

LCG, November 6, 2025--X-energy Reactor Company, LLC, (X-energy) and the U.S. Office of Nuclear Energy today announced the start of confirmatory irradiation testing at Idaho National Laboratory (INL) to qualify X-energy’s proprietary TRISO-X fuel pebbles for commercial use in the Xe-100 Small Modular Reactor (SMR). (TRISO stands for TRi-structural ISOtropic). This is the first time that TRISO-X fuel pebbles will undergo irradiation testing in a U.S. lab, which is a critical step in meeting requirements set forth by the U.S. Nuclear Regulatory Commission (NRC) for the commercial deployment of advanced reactors that will use the fuel.

NextEra Energy and Google Collaborate on Accelerating Nuclear Power Deployment

LCG, October 28, 2025--NextEra Energy and Google yesterday announced two agreements that will help meet growing electricity demand from artificial intelligence (AI) with clean, reliable, 24/7 nuclear power and strengthen the nation's nuclear leadership. First, Google signed a new, 25-year agreement for power generated at the Duane Arnold Energy Center, Iowa's only nuclear power facility. The 601-MW boiling water reactor unit was shut down in 2020 and is expected to commence operations by the first quarter of 2029, pending regulatory approvals to restart the plant.

Salt River Project Moves to Restart the Mohave Generating Station

LCG, September 29, 2006--The Salt River Project announced earlier this week that it intends to reopen the Mohave Generating Station near Laughlin, Nevada. Salt River is seeking new partners to rebuild the facility and plans to have a final environmental impact statement by the summer of 2007.

The coal-fired plant, with an electric generating capacity of 1,580-MW, was closed at the end of last year, when the 35-year operating permit expired. In order to reopen the plant, investments expected to cost $1.1 billion are necessary for a variety of improvements, including the installation of pollution control equipment required under a 1999 consent decree. Other issues include obtaining water supplies from the Hopi and Navajo tribes.

The current owners of the facility are Southern California Edison (SCE), the Salt River Project, Nevada Power Company, and the Los Angeles Department of Water and Power (LADWP), and their respective ownership percentages are: 56, 20, 14 and 10 percent.

Last June, SCE notified the other plant owners that it will no longer participate in activities to return the coal-fired plant to service. Following that announcement, LADWP stated that its focus is to decrease its investment in coal power and that it will withdraw from the plant. Nevada Power Company, a wholly owned subsidiary of Sierra Pacific Resources, stated that it is not economically feasible to continue with the plant and that it would terminate its participation in the project. A Salt River Project spokesperson stated at the time that, "We're not going to go it alone. If we are going to participate in the future, we would have to have new owners."

Now, after three months, the Salt River Project is working to develop a new group of owners to reopen the plant by 2011.
