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.

California ISO Approves Tehachapi Wind Transmission Project

LCG, July 30, 2004--The California ISO Board of Governors approved a new transmission project designed to increase transmission capacity from wind farms in the Tehachapi and Antelope Valley area to load centers in California. The current capacity of wind farms in the area is approximately 600 MW, with as much as 1,100 MW of additional wind projects planned, according to the ISO.

Southern California Edison is now expected to apply to the California Public Utilities Commission for approval to proceed and construct the 25-mile line, which is estimated to cost $94 million. The line may initially be energized at 230 kV and upgraded to 500 kV in the future. The new line could commence operations as early as December 2006.

The growth in generation from wind is driven in part by California's Renewable Portfolio Standard (RPS). The RPS requires 20 percent of the energy the Investor-Owned Utilities deliver to their customers to come from renewable resources by the year 2017.
