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 to Restart Nuclear Reactor

LCG, July 7, 2004--Ontario Power Generation (OPG) received approval to proceed with a project, budgeted now at $900 million, to refurbish and restart unit 1 at the Pickering A Generating Station located east of Toronto. The decision is driven in part by the estimate that the 515 MW nuclear unit can begin producing power in just 15 months - more rapidly than other alternatives - to meet growing electricity demands and to compensate for the government's planned closure of coal-fired plants, including the 1,150 MW Lakeview Station in April 2005.

The approval to proceed with unit 1 follows a troublesome past with Pickering refurbishment efforts. The first of four Pickering A reactors returned to service in September 2003, more than two years late and at a cost nearly three times that approved by the Board of Directors of OPG. Ontario Energy Minister Dwight Duncan vows this won't happen again. "The lack of transparency and accountability at OPG under the former government led to a serious waste of money - we will do things differently," Duncan said. "I am not willing to write OPG another blank cheque. I have directed OPG to report regularly to the public on the progress of this project, and we have an independent auditor in place to help ensure the project stays on track."
