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.

Fire During Restart Shuts San Onofre Nuke

LCG, Feb. 5, 2001The San Onofre Unit 3 nuclear power plant belonging to Southern California Edison Co. shut down automatically yesterday when a fire erupted in an electrical switching room.

The 1,120 megawatt reactor, which had just been restarted after completing a refueling outage begun January 2, was increasing power when the fire occurred. No radiation was emitted and no one was injured in the mishap, according to Ray Golden, a spokesman for the utility.

During the automatic shutdown called a "trip" all systems functioned properly. "Everything did exactly as it was designed to," Golden said.

The fire broke out 12 hours into the restart process, when the reactor was at about 40 percent of full power. Firefighters extinguished the blaze in about 30 minutes, Golden said, and the reactor itself was never endangered by the fire.

Investigations into the cause of the fire were continuing today and no estimate was available for how long repairs would take. Golden said the unit could be off-line for several weeks.
