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.

Northwest Power Picture Brightens

LCG, June 6, 2001The energy crunch affecting the Pacific Northwest is loosening, according to a report in this morning's Seattle Times, and none of the improvement can be laid to increased rainfall.

New supply that is, additional sources of electricity beyond the region's highly developed hydroelectric infrastructure has brightened the picture, with better reliability forecast for summer and lower regional rate increases this coming fall, the paper said.

"Things are looking better than they were," Mark Crisson, director of Tacoma Public Utilities, told the Times. "In fact, I think there is going to be a huge overreaction to the situation in terms of new supply. If we had had anything close to a normal water year, we wouldn't even be having this conversation."

Bonneville Power Administration says it has received transmission applications for between 25,000 and 30,000 megawatts of proposed power plants. Ed Mosey, a spokesman for Bonneville, said "There isn't a site in the Northwest with a source of gas and transmission capacity that isn't being looked at." Most of the plants won't be built, but enough will to ease the crunch in future years, if not this.

The Northwest Power Planning Council announced May 25 that power supplies are expected to be reliable throughout the summer, with no risk of blackouts. That does not mean the Northwest is immune into the fall and winter. If the drought continues, a shortage of power, with blackouts, is possible.
