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.

Santee Cooper Suspends Development of Coal-fired Power Plant in South Carolina

LCG, August 25, 2009--The board of Santee Cooper, South Carolina's state-owned electric and water utility, yesterday voted unanimously to suspend efforts to construct a 600-MW, coal-fired electric generating station in Florence County, South Carolina.

Santee Cooper identified three, primary reasons for discontinuing its efforts towards building the Pee Dee Energy Campus. First, the recession has reduced overall demand for electricity. Second, proposed federal government regulations regarding carbon emissions would significantly increase the operating costs of the coal-fired power plant. Third, Central Electric Power Cooperative, Santee Cooper's largest customer, plans to gradually reduce its reliance on using power supplied by Santee Cooper beginning in 2013.

The Pee Dee Energy Campus was scheduled to commence operations in 2012.
