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.

International Power Plans 580 Megawatt Long Island Plant

LCG, June 26, 2001International Power Plc, the British global energy company formed from the breakup of National Power, said this morning it has applied to New York state regulators for permission to build a 580 megawatt natural gas-fueled, combined-cycle power plant in Brookhaven on Long Island.

The company said the New York State Board on Electric Generation Siting and the Environment will have 60 days to determine whether the application is complete and, if it is, another year to reach a final decision on the plant.

Under this schedule, International Power said it hopes to begin construction of the Brookhaven plant in the second half of 2002 and have the plant ready for commercial operation in late 2004.

"Brookhaven will provide 580 megawatts of clean and affordable new generating capacity to the supply constrained Long Island power market where electricity prices are high and power plant siting is very difficult," said Peter Giller, International Power's chief executive.

The New York Independent System Operator has estimated that 8,600 megawatts of new generation is required in the State by 2005 to avoid higher prices and the possibility of unreliable supplies. Presently, only about 1,700 megawatts of new capacity is under construction in New York.
