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.

January Gas Shortage in New England Under Investigation

LCG, Jan. 27, 2004--A shortage of natural gas and simultaneous high power prices that occurred in New England in mid-January are the subject of an investigation by the Federal Energy Regulatory Commission's Office of Market Oversight and Investigations, division Director William Hederman, Jr. told Connecticut officials.

The investigation will try to establish whether the reason for the elevated power prices and tight power supplies was based in market fundamentals alone, or whether other factors contributed. The FERC investigation was prompted by a request by Connecticut Attorney General Richard Blumenthal. Blumenthal has been investigating the possibility that power generators chose to sell gas at high prices rather than use it to generate electricity.

The ISO New England, which manages the regional power grid, had warned on Jan. 15 that it was prepared to trigger rolling blackouts if a failure on a line or at a generator made it necessary. The warning was dropped the next day, when the number of available units rose. Blumenthal stated last week that the ISO could have created conditions that led to fewer generators being available. In a statement, the ISO asserted that it had done everything possible to ensure availability of power supplies, although rules that permit generators to sell gas if the plants are not needed for reliability are under review.
