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.

NRC Braces for New Nuclear Plant Applications

LCG, April 12, 2001The Nuclear Regulatory Commission is getting ready for a spate of applications from companies wanting to build new nuclear power plants in the United States, a spokesman for an industry association said yesterday.

"We do expect you may begin to see some applications to the Nuclear Regulatory Commission for early site permits perhaps as soon as next year," said Steve Kerekes, a spokesman for the Nuclear Energy Institute.

Under NRC procedures, an application can be made in two or more phases. A developer can ask the commission rule only on environmental and siting issues and not return to those matter when proceeding further into the permitting process.

While the NRC has not issued a new license since 1973, looming electricity shortages coupled with continued concern about emissions from conventional power plants have rekindled interest in the clean-running nukes.

A spokesman for the NRC said "We are taking some steps to prepare for the possibility of new applications," adding that application procedures have also been streamlined. "Before, you had to apply for a construction permit and then an operating permit, those two procedures have now been consolidated."
