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.

Duke Energy North America Plans Three Merchant Plants

LCG, Jan. 14, 2002--Duke Energy North America has signed contracts with Duke/Fluor Daniel to design and construct three merchant generating plants worth a total of 2,420 megawatts of new capacity.

Jeff Faulk, president and chief executive officer of Duke/Fluor Daniel noted, "This brings our portfolio of active EPC projects to more than 16,000 megawatts of fossil-fueled power generation." The plants will be located in three disparate areas within the western states. The Luna Energy Facility will be located in Luna County N.M., and will have a nameplate capacity of 600 megawatts. In Grays Harbor County, Wash., the 620-megawatt Grays Harbor Energy Facility is planned. Moapa County, Nev., will be home to the 1,200-megawatt Moapa Energy Facility.

Each of the power plants will be a combined-cycle facility, fired by natural gas. Commercial operation of the plants, which will utilize eight General Electric-7FA combustion turbines, is expected starting in the summer of 2003.

Jim Donnell, president and chief executive officer of DENA commented that with Duke/Fluor Daniel's record, he believed that "these facilities will be providing competitively priced power to the western United States when demand peaks in the summer."
