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.

TVA Pursues License Extension for Sequoyah Nuclear Plant
LCG, February 12, 2013--The Tennessee Valley Authority (TVA) recently announced that it completed a comprehensive application with the Nuclear Regulatory Commission (NRC) for a 20-year extension of the operating licenses for both units at Sequoyah Nuclear Plant.
The current, 40-year operating licenses expire in 2020 and 2021. The 20-year license extension will enable operation of the units, each with an electric generating capacity of approximately 1,160 MW, until 2040 and 2041. The NRC authorized renewal of 20-year operating licenses for TVA's Browns Ferry units 1, 2 and 3 in 2006.
TVA's Chief Nuclear Officer stated, "By applying for a 20-year extension of our current operating license now, we are affirming to the NRC that our plant is safe and in solid material condition. Extending the operating life of this nuclear plant supports TVA's vision to provide low-cost, cleaner electricity and a balanced energy portfolio."
TVA expects the license renewal process to cost approximately $23 million, including NRC charges to TVA to review the applications. TVA's Board of Directors approved the recommendation to submit the necessary paperwork to file a license renewal application. TVA submitted its operating license extension applications to the NRC on January 15.
The license application process will include local public meetings held by TVA over the next two years, and the scope will addresses specific requirements to assure safe plant operation. TVA stated that, as part of its application, it developed its own environmental report to support the NRC review.
