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.

Gulfstream Pipeline Extension in Florida to Begin Construction

LCG, July 16, 2004--Construction on the extension of the Gulfstream natural gas pipeline was initiated this week. When completed, the extension will allow the 1.1 Bcf/day pipeline access to new markets, including power plants, such as the planned expansion of Florida Power & Light's Martin Station. The 110-mile extension of mainline will extend from Polk County to Martin County and will also require construction in Hardee, Highlands, and Okeechobee Counties. The expansion is scheduled to be complete in December 2004.

Gulfstream, a joint development between Williams and Duke Energy, was placed into service in May 2002 and is the first new natural gas pipeline into Florida in over 40 years. The pipeline receives gas from Mobile Bay, East Louisiana and Mississippi before crossing more than 400 miles of the Gulf of Mexico.

The Martin Station expansion proposal calls for converting two combustion turbine peaking units, along with two new combustion turbines, into more efficient combined-cycle natural gas generation providing an additional 800 MW.
