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.

Colorado Pursues Wind Power

LCG, August 24, 2004--Last week Xcel Energy received approval from the Colorado Public Utilities Commission to add at least 500 MW of wind capacity to its energy portfolio by 2006. The Xcel wind plan is contingent upon Congress extending the production tax credit this year.

It was also announced last week by the Colorado Secretary of State that the Colorado Renewable Energy Initiative had gathered enough signatures to place the initiative on the ballot. The initiative, opposed by Xcel, would require electricity providers serving more than 40,000 customers to use 10 percent or more of power from renewable sources by 2015.

In spite of delays in the extension of the production tax credit, wind power and renewables are gaining momentum as sixteen states and a number of municipalities set long-term renewables goals that require a significant portion of energy be supplied by renewables. For example, California's Renewable Portfolio Standard (RPS) requires 20 percent of the energy the Investor-Owned Utilities deliver to their customers to come from renewable resources by the year 2017. To pursue these goals, both San Diego Electric & Gas and Los Angeles Department of Water and Power issued Requests for Proposals (RFPs) for renewables last month.
