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.

Peabody Energy Receives DOE Grant for New Mexico Power Plant

LCG, October 19, 2004--Peabody Energy received a $19.7 million Clean Coal Power Initiative grant from the U.S. Department of Energy fordemonstrating technology to achieve ultra-low emissions at the proposed 300 MW Mustang Energy Project located near Peabody's Lee Ranch Coal Company operations in New Mexico.

The plant would demonstrate on a commercial scale a technology that operates in a manner similar to a traditional scrubber system. The system will employ sodium bicarbonate (baking soda) in the scrubber and is expected to achieve 99.5 percent removal of sulfur dioxide, 98 percent removal of nitrogen oxide and 90 percent removal of mercury. The sulfur and nitrogen byproducts will be used to create high value, granular fertilizer. The plant will use low-NOx burners, fabric filtration and a dry cooling system to minimize emissions and water consumption. The Department of Energy grant will be repaid as the technology is demonstrated.

Peabody's announcement did not include a target operational date or information regarding buyers of the plants output.
