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.

NRC Optimistic About Restarting TVA's Browns Ferry Nuclear Reactor

LCG, November 2, 2006--The chairman of the Nuclear Regulatory Commission (NRC) stated Tuesday that restarting Unit 1 at Browns Ferry Nuclear Plant in May of next year appears quite "doable." The reactivation of Unit 1 will add 1,200 MW of capacity to the generating fleet of the Tennessee Valley Authority (TVA).

TVA is the owner and operator of the plant, which is located beside Wheeler Reservoir on the Tennessee River, near Athens, Alabama. There are three General Electric boiling water reactors at the plant. Unit 1 commenced commercial operation on August 1, 1974, but safety concerns led to its closure in 1985. Units 2 and 3 were also closed for a period but returned to operations in the late 1990s and are currently generating power.

TVA plans to restart Unit 1 in May 2007 following plant upgrades that are estimated to cost $1.8 billion.

The TVA Board voted to return Browns Ferry Unit 1 to service in May 2002.
