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.

1,300 Megawatt Idaho Power Plant Planned

LCG, April 17, 2001The year-old independent power producer Newport Generation Inc. said yesterday it plans to build a 1,300 megawatt power plant in Rathdrum, Idaho, 32 miles northeast of Spokane, Wash.

"Rathdrum is an ideal location for energy development since its proximity to key transmission infrastructure is unique," said Scott Noll, vice president for development. "Both a Bonneville Power Administration electric transmission line and a PG&E Gas Transmission Northwest natural gas pipeline intersect the site."

The Kootenai Power Project is planned for a portion of a 320-acre site adjacent to a new 250 megawatt power plant currently under construction by Avista Energy, Inc. and Cogentrix. Upon completion in 2004, the $550 million natural gas-fired combined cycle plant will generate electricity equivalent to that required to meet the needs of a city the size of Seattle, Newport said.

"The Northwest needs electric power and the Rathdrum area's strategic position has attracted power developers," said Robert Kahn, Newport's public affairs director. "We fully expect that our commitment to clean energy and environmental protection will result in a model project."
