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.

Florida Commission Approves Seminole's Proposed Coal-fired Power Plant

LCG, July 19, 2006--The Florida Public Service Commission (FPSC) yesterday gave unanimous consent to a new, 750-MW coal-fired power plant proposed by Seminole Electric Cooperative, Inc. (Seminole). Seminole filed a Certificate of Need to construct the electric generating unit in Putnam County, Florida with the FPSC in March.

The plan is to add a third, coal-fired unit at Seminole's existing 1,300 MW Seminole Generating Station. The schedule calls for commercial operations to commence on May 1, 2012. The power from the new plant is needed to meet the growing electric load of Seminole's ten member cooperatives.

Seminole's plans include upgrades to the existing units designed to reduce air emissions. The new emission control equipment includes selective catalytic reduction (SCR) systems to reduce nitrogen oxide (NOx) emissions and scrubber systems for better removal of sulfur dioxide (SO2). A co-benefit of the upgrades is the reduction of mercury emissions. The emission control work on the existing units is to begin this year and to be completed by 2010.

The total project is estimated to cost $1.4 billion, including over $250 million to improve emission controls at the existing coal units.
