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.

Construction Starts on California's Sunrise Power Plant

LCG, Dec. 12, 2000--The Edison Mission Energy unit of Edison International Inc. started construction yesterday on its Sunrise power plant in the badlands west of Bakersfield, Calif. The company learned last Thursday that the California Energy Commission had given it permission to proceed with a "temporary" first phase of the plant.

It had taken the state power plant licensing agency two years to decide that a power plant would be okay in the middle of the 74-square-mile Elk Hills Oil and Gas Field.

Edison Mission Energy said the new facility "will bring both short- and long-term generation capacity to the state, which is in dire need of new power generation."

The Energy Commission approval is good only for two years, during which Sunrise will operate as a simple-cycle peaking plant. When the license expires on Dec. 31, 2002, the plant will have to either shut down or get a new license to operate as a combined-cycle facility or a cogenerator. Edison plans to keep the plant operating.

The Sunrise Power Project will be completed in two phases. Phase 1 will consist of a 320 megawatt, simple-cycle peaking facility scheduled to be in service during the summer 2001. Phase 2 willconvert the peaking facility to a 560 megawatts, combined-cycle operation with an in-service date ofsummer 2003.
