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.

New England Ready for Summer, ISO Says

LCG, May 18, 2001The operator of New England's bulk power grid said yesterday that there should be a sufficient supply of electricity to meet the summer needs of the region, refuting in part a report released Tuesday by the North American Electric Reliability Council.

ISO-New England said that NERC did not take into account firm agreements with Hydro-Quebec of Canada for at least 1,500 megawatts of power.

In its Summer 2001 forecast released last month, the ISO said that despite projected record-setting demand the region should not face blackouts, but conceded that extremely hot days or an extended heat wave could require the implementation of conservation measures.

"ISO New England is forecasting an adequate supply of electricity for the New England region thissummer," Stephen G. Whitley, vice president for system operations, said. "New England does not face the supply problems that are at the root of the crisis in California. Because of the addition of several new power plants throughout the New England region over the past two years, the growth in supply is outpacing the growth in demand."

With 1,000 megawatts of new electric generation added since June 2000, and another 1,600 megawatts expected to be on-line this summer, New England projects a reserve margin of almost 19%, which is higher than most other areas of the country, the ISO said.
