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 Utilities Will Buy Power in 2003

LCG, Oct. 25, 2002--The California Public Utilities Commission (PUC) yesterday mandated that beginning Jan. 1, 2003, Pacific Gas & Electric Co., Southern California Edison, and San Diego Gas & Electric must start buying power for their customers again, and will have access to interest-free credit from the state if necessary.

The Department of Water Resources will exit from its role as buyer of power at the end of this year, although it began buying power through long-term contracts signed during last year's energy crisis. Only a minimal percentage of overall supplies will be purchased by the utilities, which will be assigned the contracts.

The PUC also said that it would move from reviewing decisions made by the utilities after the fact to a new regulatory mode, of going over plans in advance of their execution. The investor-owned utilities have pushed for such treatment in cases in which unforeseen regulatory factors came to light once they had pursued initiatives on their own.

The President of the PUC, Loretta Lynch, said that with the ruling, "the utilities are back in business." It found that the utilities' projected purchases are "well within their ability to finance."
