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.

Bush to Speed Cross-Border Permits with Mexico

LCG, March 9, 2001U.S. Energy Secretary Spencer, in Mexico City for the Fifth Hemispheric Energy Ministers Meeting, said yesterday the Bush administration will speed up the permitting process for electricity ties with Mexico.

Acknowledging the benefits of U.S. Mexican trade in electric power, Abraham said transmission arrangements were among the biggest obstacles. He said he had discussed the permitting process with Mexican Energy Minister Ernesto Martens and with Alfred Elias Ayub, director of the Comisin Federal de Electricidad.

Though Mexico has power shortages of its own, several new power plants in northwestern Mexico are under development with an eye to exporting power to California. One such plant, to be built in Mexicali, 10 miles south of El Centro, Calif., will require permits just to send its power to Calexico, Calif., which is across the street.

Abraham said "We are going to do our best to try to make this process work better, consistent with the goals of having a legitimate permits process." He had said earlier that the Energy Department would issue a permit for a cross-border connection at Brownsville, Texas.

But Abraham pointed out that there was room for lots of improvement within the U.S. If Mexican power were imported into Southern California, it might go no further because of constraints in California's aging transmission grid. He said California's problems have led the administration to take a closer look at the situation throughout the United States.
