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.

IMO Forecasts Improved Electricity System Reliability for Ontario

LCG, June 24, 2004--The Independent Electricity Market Operator (IMO) issued yesterday its 18-month outlook for the Ontario electricity system, describing the reliability over the next 18 months as "substantially improved compared with the outlook presented one year ago." The reliability improvements are driven by the recent and near-term addition of 2,800 MW of capacity, consisting of five new gas-fired plants coming on line by August 2004, together with the return to service of three nuclear units. However, forecast reserves relative to requirements will be tight at times, particularly during the fall of 2004 when generator outages are expected for maintenance purposes. For reliability needs, the IMO may act to cancel some planned generator outages.

In April 2005, the planned shutdown of the 1,150 MW, coal-fired Lakeview Station will reduce generating capacity and emphasizes the need for Hydro One to complete related transmission improvements currently underway in the Greater Toronto Area.

To meet future system reliability objectives, the Ontario government plans to issue a Request for Proposal for up to 2,500 MW of new generating capacity and/or demand-side management initiatives to be developed as early as 2005.

How the Pickering nuclear station reactors, located east of Toronto, will fit into the future resource plan remains unclear. Of the four Pickering nuclear reactors, only one was restarted last fall, behind schedule and over budget. The other three (Pickering A Units 1 to 3) are moth-balled - and not assumed to be available in the IMO's the 18-month forecast. Last week, the board at Ontario Power Generation recommended to the government that a second reactor at the Pickering A generating station should be restarted.
