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.

White House Asks EPA to Delay Air Standard Review

LCG, Aug. 16, 2001--In response to a request from the Bush administration, the Environmental Protection Agency has delayed until next month issuing proposed revisions to the so-called "new source review" affecting maintenance and repair of existing power plants.

As part of his energy program, President Bush had asked the EPA to submit recommendations on the new source review after a 90-day study. The 90 days is up tomorrow, and the agency has agreed to delay its recommendations until the administration introduces comprehensive pollution legislation in September.

"We will put forward an ambitious proposal that will reduce air pollution from power plants significantly more than the existing system. Subsequently, we will release the NSR report called for by the National Energy Policy," EPA Administrator Christine Todd Whitman said in a statement.

Under the Clean Air Act, utilities making significant changes to existing power plants that resulted in boosting their output were required to install emissions controls. The Clinton administration interpreted the requirement to include routine repairs and maintenance that did not otherwise change the plants. The Clinton EPA then sued several large utilities to force compliance and seek penalties.

While Whitman has not tipped her hand, the EPA review is expected to recommend a system of standards limiting emissions of nitrogen oxides, sulphur dioxide, mercury and particulate matter, while allowing power plant operators to achieve the standards in any way they find best.
