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.

DOE Submits Application for Yucca Mountain Nuclear Waste Repository to NRC
LCG, June 4, 2008--The U.S. Department of Energy (DOE) submitted an application to the Nuclear Regulatory Commission (NRC) for a license to construct the country's first underground, geologic repository for spent nuclear fuel and high-level nuclear waste at Yucca Mountain, Nevada. The application is over 8,600 pages long, plus approximately 200 other supporting documents, including a Final Environmental Impact Statement (FEIS).
Nuclear wastes are now stored at 121 temporary locations in 39 states. In 2002 Congress and the President approved Yucca Mountain to be the site for the country's first permanent geologic repository for spent nuclear fuel and high-level radioactive waste. With the application submitted, the NRC will determine whether the application is sufficiently complete. If deemed complete, the NRC will formally docket the application and publish a notice of opportunity to request a hearing before the NRC?s Atomic Safety and Licensing Board. In addition, the NRC will announce the extent to which it will adopt the DOE?s FEIS for the proposed repository, located approximately ninety miles northwest of Las Vegas in the Mojave Desert.
After the NRC formally dockets the application, the NRC will follow a prescribed, three-year schedule to decide if construction should be authorized. The NRC may request a one-year extension, and the NRC has stated it expects it will need the extension.
To address the myriad of scientific environmental and engineering issues, the NRC plans to utilize a team of over one hundred contractors and staff employees, including staff at the NRC?s headquarters in Rockville, Maryland, the Region IV office in Arlington, Texas, and the NRC?s Las Vegas office. Further technical support will be provided by the Center for Nuclear Waste Regulatory Analysis in San Antonio, Texas, a federally funded research and development center.
