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.

Montana Power Gets Farther Away from Power

LCG, June 26, 2001Montana Power Co. said this morning it has arranged to buy out the remaining term of a power supply contract with an industrial customer, removing the former electric utility's exposure to uncertain future energy prices.

The agreement involves a one-time payment by Montana Power of $62.5 million to Advanced Silicon Materials LLC and ends, as of June 30, the power supply contract that was in effect until the end of next year.

Montana Power will soon be entirely out of the power business and will be a telephone company called Touchamerica, or maybe Touch America.

Bob Gannon, Montana Power's chief executive, said "This action terminates a legacy industrial energy-supply obligation on generally favorable terms, and the contract has been removed from our agreement with North Western Corp., the buyer of our utility business."

"We have enjoyed a good working relationship with Montana Power," said Advanced Silicon's Mike Kerschen. "They were an excellent partner, and we are happy to support their need to transition away from energy to telecommunications."
