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.

Governor Approves Sunflower's Proposed Coal-fired Plant in Kansas

LCG, May 20, 2009--The new Governor of Kansas, Mark Parkinson, approved on Monday an agreeement that includes a coal-fired, electric generating unit proposed by Sunflower Electric Power Corporation (Sunflower).

The approval permits the construction of a single, 895-MW unit at an existing power plant near Holcolm, Kansas. The approval follows a settlement negotiation that resulted in a single, 895-MW unit, rather than two, 700-MW units.

Governor Parkinson recently replaced Kathleen Sebelius, who became U.S. Secretary for Health and Human Services. While governor, Ms. Sebelius denied an air quality permit for Sunflower's proposed coal-fired unit and vetoed three measures submitted by the Legislature to overturn the decision to reject the permit.

The Kansas Legislature adjourned the 2009 session last week with an energy plan that included Sunflower's 895-MW, coal-fired unit.
