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.

Ontario Competition Could Be Slowed by Credit Fears

LCG, Feb. 27, 2002--Although a competitive power market is due to begin in Ontario on May 1, acquisitions of Ontario Power Generation's power-producing assets have been slow enough that the spin-off of utility Ontario Hydro still owns 80 percent of the province's generating assets.

Ontario Power's management attributes the slow pace of divestiture to banks' Enron-inspired fear of utility credit problems. Ron Robinson, vice-president of portfolio management at OPG said, "they don't have the money to come in and invest. Not only are they withdrawing their interest, they're going home to take care of their balance sheets."

The provincial transition plan for full competition requires that within ten years, no more than 35 percent of Ontario electric output should come from OPG. The single major competition-related development in the province to date has involved Bruce Power, a partnership of British Energy Plc and Cameco Corp., a Canadian uranium supplier. Bruce Power's nuclear assets, which it is leasing from OPG until 2018, produce 17 percent of the province's electric power needs.

Some heavy industrial users have voiced concern that unless divestiture accelerates, power prices could increase. Lauri Gregg, of Falconbridge Ltd., the third-largest nickel producer in the world, said, "the faster we get competition the faster we get efficiency in the market." Gregg mentioned that Falconbridge had urged a five-year timetable instead.
