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.

Maritimes Pipeline to Provide Gas to New Hampshire Plant

LCG, May 18, 2001The Maritimes & Northeast Pipeline LLC said yesterday it reached an agreement with an ad hoc subsidiary of Consolidated Edison Inc. to provide natural gas transportation service to a 525 megawatt power plant currently under construction in Newington, N.H.

The plant, being developed by Con Edison affiliate Newington Energy LLC, is scheduled to begin commercial operation next year. Maritimes & Northeast intends to build a connection to the plant from an existing lateral near the plant.

"With natural gas from the Maritimes pipeline, we will be able to produce cleaner, low-costelectricity for the people of New Hampshire and New England," said Michael Madia, a Newington vice president.

Maritimes & Northeast transports natural gas from the Sable offshore project near Nova Scotia. When the pipeline went into service last year, it bought gas to parts of the U.S. Northeast that had never had the fuel.

Maritimes & Northeast is jointly owned by affiliates of Duke Energy Corp. (37.5 percent), Canada's Westcoast Energy Inc. (37.5 percent), Exxon Mobil Corp. (12.5 percent); and Emera Inc. of Nova Scotia (12.5 percent).
