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.

Duke , GPU in South Australian Gas Pipeline

LCG, June 27, 2001Subsidiaries of Duke Energy Corp. and GPU Inc. said yesterday they had formed an alliance to build a natural gas pipeline in Australia, running more than 400 miles from southwestern Victoria to Adelaide in the state of South Australia.

South Australia faces a shortage of natural gas as its current supply comes mostly from the Cooper Basin, which is in decline. Phil Grigsby, commercial development manager for Duke Energy International, said gas from the Gippsland Basin or gas fields proposed to be developed in western Victoria, including new Otway Basin discoveries over the past month could be shipped to Adelaide over the new pipeline.

Both Duke and GPU Gas Net had separately explored the possibility of building a Victoria to South Australia pipeline before the two companies formed their alliance.

Pending the results of a binding open season, the new pipeline could be built in a little more than two years and begin delivering natural gas by the end of 2003, Grigsby said. "I think this is a significant step. The combined efforts of a Duke International and a GPU put a lot of momentum behind a project," he said.

Duke said TXU Australia, which owns the Torrens Island Power Station in South Australia, would be an anchor customer of the new pipeline. Others could be Australian National Power, a subsidiary of the UK's International Power Plc, and the South Australian Magnesium Project.
