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.

Proposal for New Generation on Long Island Presented to Locals

LCG, January 7, 2005--Caithness Energy and the Long Island Power Authority (LIPA) presented their plans to build a 326-MW, combined cycle generating station on Long Island to the Bellport area residents. Caithness Energy is the developer of the North Bellport Energy Center and will construct and operate the plant, and LIPA has agreed to sign a long-term contract to purchase 85 percent of the electricity generated, with the remainder sold to the wholesale market.

LIPA is acting as the lead agency for the Caithness project, as it is the primary government agency to support and approve construction and operation of the proposed generating station. The station will be located on a 96 acre site in an industrial area. Caithness plans to start construction in the spring of 2006, given approval from various agencies, including the town of Brookhaven.

The station is estimated to cost $375 million, and the gas-fired units will use oil as a back-up fuel. The plant is proposed to meet growing demands that are currently served by aging generating stations and imports, which are severely limited by transmission constraints.
