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.

Entergy's UK Saltend Project at Full Capacity

LCG, Sept. 19, 2000British contractors building the 1,200 megawatt Saltend power plant in England for Entergy Corp. of the U.S. cranked all three units up to full capacity yesterday to begin a test period before the facility is put into commercial operation, a spokeswoman for the project said this morning.

"On Wednesday the plant will start a 10-day testing phase before the formal handover by theconstructors," she said.

The natural gas-fired plant was the last large gas-fueled plant in the United Kingdom to win regulatory approval before a moratorium on the use of gas as electric generation fuel went into effect to protect jobs in the British coal mining industry.

Saltend was originally scheduled to begin commercial operations by June of this year, but construction problems forced a delay. The delays may not be over, the spokeswoman said. "Testing can take longer than expected but (10 days) is the plan at the moment," she said.

Saltend was hooked to the UK's national grid last May and has been selling some power in the England and Wales Electricity Pool, the British wholesale market, since that time.

Entergy has, for about a year, seeking a partner to buy up to a 50 percent interest in Saltend. Such a deal could take place after the plant is declared fully operational.
