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.

Roseville, CA Considers Plant Construction

LCG, November 26, 2002-After ending its contract with an Enron subsidiary, the California city of Roseville's local council has begun contemplating constructing Roseville's own power plant.

The city, located some 20 miles northeast of Sacramento, had a deal with Enron subsidiary Roseville Energy Facility LLC to construct a 750-megawatt plant. Last week the City Council decided unanimously to cancel the contract with the company, as the company had failed to pay $100,000 it owed the city.

The city has since kept $600,000 in fees collected from Enron and has been considering building its own, one- or two-hundred megawatt facility.

Roseville is currently dependent upon electricity generated far away, and the city is interested in the reliable electricity a local plant could provide.

Some residents are already worried about pollution from local construction, although the plant would be smaller than the one previously planned.

Roseville is in Placer County and has a population of about 80,000.
