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.

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.

SCE&G's Summer Nuke Prepares to Restart
LCG, Feb. 21, 2001South Carolina Electric & Gas Co. said yesterday it expects to restart its Summer nuclear power plant near Parr, S.C. early next month. The plant has been shut down since last October when, during a routine refueling outage, a crack was discovered in a weld on a coolant pipe.The company had hoped to restart the 1,000 megawatt plant in January or early this month, but those coolant pipes are big, measuring two and one-half feet across, and working on a cracked weld requires a cold reactor.During the outage, about a third of the plants fuel has been replaced and hundreds of maintenance items have been attended to, the company said., and that weld has been repaired." We're actually in the process of restarting right now," a company spokesman said, referring to the many steps that need to be taken before the reactor actually begins its chain reaction. "We expect it back on line in early March."Summer is two-thirds owned by SCE&G and one-third by the South Carolina Public Service Authority.
