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.

OUC Acquires Osceola Natural Gas Power Plant

LCG, September 30, 2021--OUC (Orlando Utilities Commission) announced yesterday that it completed on Tuesday its purchase of the Osceola Generating Station, a 510-MW, natural gas-fired power plant located near Harmony in Osceola County, Florida. OUC announced plans to purchase the 20-year old, inactive facility last month.

The acquisition of the Osceola plant with three, dual-fuel gas turbines that can be rapidly powered up or down can complement growth in intermittent solar power installations in the area. OUC states that the nearly $100 million deal to purchase and upgrade the inactive plant from Genova, a Texas-based private ownership group, will not change OUC’s commitment to net zero CO2 emissions as outlined in its Electric Integrated Resource Plan (EIRP), the utility’s 30-year energy roadmap.

The acquisition will allow OUC to retire its oldest coal-fired power plant, Stanton Unit 1 that began operations in 1987 at the Stanton Energy Center, rather than converting the facility to natural gas, as stated in the EIRP. OUC has not determined Unit 1’s retirement date but states that it remains committed to significantly reducing coal fired generation no later than 2025 and eliminating it no later than 2027.

OUC’s General Manager and CEO stated, “As we move forward with our clean energy transition, ensuring operational flexibility is essential to maintaining reliability, resiliency, and affordability for our customers. We are also committed to continued investments in solar and energy storage. This purchase of peaker generator units positions us to better manage the solar production fluctuations caused by cloud cover in Florida.”

Under the EIRP, OUC plans to increase the use of renewable energy resources and encourage conservation to reach net zero CO2 emissions by 2050, with interim carbon emissions reductions of 50 percent and 75 percent by 2030 and 2040, respectively.

OUC’s transition away from coal in Florida is not unique. JEA and Florida Power & Light Company (FPL) acted in June 2020 to transition away from receiving power from a coal-fired unit at Plant Scherer in Georgia.
