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 PUC Critical of Power Buying Agency Request

LCG, Dec. 19, 2002--The president of the California Public Utilities Commission (CPUC), Loretta Lynch, said this week that a request by the California Department of Water Resources (CDWR) for funds from the state's major utilities could include one billion dollars of "wholly unnecessary" charges.

The CPUC, which has no authority to adjust the requested $4.5 billion based on its assessment, found that PG&E should pay the CDWR nearly $2 billion, Southern California Edison around $1.9 billion, and San Diego Gas & Electric slightly above $640 million in 2003. The transfers are to repay the state for long-term purchase agreements made on behalf of the utilities when power sellers considered the utilities to lack creditworthiness.

Lynch said she hoped the size of the request would be trimmed, based on the planned end to the state's power purchases at the start of next year, which will put the utilities back in the business of purchasing it themselves. In response, Oscar Hidalgo, a spokesman for the CDWR, noted that uncertainty lingers about whether the transition will happen smoothly, and that the request allows for reserves. "There's nothing we'd like to do more than to lower our revenue requirement if the opportunity presents itself. We're not a profit-maker. We're trying to exit this business," Hidalgo said.
