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.

Effects of Largest North American Power Outage Linger in Ontario

LCG, Aug. 18, 2003--Last week's power outage is still being felt in Ontario, where the province's Independent Electricity Market Operator, or IMO, instructed businesses, industry and consumers to curtail energy usage.

The premier of Ontario, Ernie Eves, commended businesses for responding so diligently to a request he made for cuts of 50 percent. Power usage is not supposed to return to normal levels yet, as most government workers were told to stay home today, and auto production plants shifted some workers to night shifts in order to lower peak demand.

The IMO said generating resources could provide up to 19,700 megawatts, below the usual level of about 21,900 megawatts that would be needed for this time of year. Conservation is needed to provide a generous reserve margin, and avoid levels of demand that could reach up to 24,000 megawatts given hotter weather and normal working conditions.

Eves commented, "We can't use every single megawatt of power that we have in case of a maintenance problem somewhere in the system." It was unknown whether activity would be allowed to increase Tuesday, although all modes of public transportation, including the energy-intensive subway, were again available this morning at 6 A.M. for commuters.
