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.

Dominion Reaches Agreement on Emissions Plan for Salem Power Station

LCG, May 27, 2005--Dominion, one of the largest energy companies in the nation, announced that it has signed a consent order with the Commonwealth of Massachusetts and other stakeholders for a plan to reduce emissions at the Salem Power Station that will result in the station meeting State emission regulations.

The plan includes commitments from Dominion to keep the 745-MW plant, which is equipped to burn coal and oil, operating through at least September 30, 2008. The plant is a key source of jobs and tax revenues for the community. Dominion purchased the plant on January 1, 2005 from the bankrupt from USGen, which had threatened to close the plant to avoid the costs of installing emission control equipment.

One element of the plan is to change the quality of coal in order to reduce sulfur dioxide (SO2), nitrogen oxides (NOx), and mercury emissions from the station. Modifications to enable the fuel handling system to use low-emissions coal will also be required.

ISO New England had determined the plant is needed for grid reliability purposes and had moved to block the closure of the station. The new agreement regarding how the emissions will be reduced and how costs will be allocated was filed Wednesday with the Federal Energy Regulatory Commission, which must approve the pact.
