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.

FERC Will Not Hear California Settlement Complaints

LCG, Oct. 22, 2003--There is no basis for the Federal Energy Regulatory Commission's consideration of objections to the terms of settlements relating to alleged market manipulation in California in 2000-2001, the agency has said.

The conclusion was justified by commissioners' contention that the matters that had led to settlements were investigations, and that parties outside the investigations, such as California officials or representatives of energy purchasers, were not qualified to instigate a review process. The agency said that any opinions it had previously issued that had indicated otherwise were being rescinded.

William Massey, the single Democrat among the Commissioners, objected to the announcement, and said that evidence in the investigations had come from those who were not being allowed to raise objections.

The issue of what California has claimed are $9 billion worth of refunds is being treated in a separate proceeding. The refunds that should ultimately be paid based on FERC's analysis are still being determined. Final determination can only be made once computer models used in the analysis have been finished. The expected date for the calculations is in the spring.
