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.

New IGCC Project Under Consideration in Indiana

LCG, March 10, 2005--Tondu Corp. is exploring the development of a new, coal-fired electric generating station in St. Joseph County, Indiana, and the project is under review by local officials. The 500-MW, advanced plant is based upon an integrated gasification combined cycle design that would be fueled by a mix of coal and petroleum coke. The project site under consideration is near New Carlisle and was previously targeted by Allegheny Energy Supply for the construction of a natural gas-fired, generating station.

The integrated gasification combined cycle (IGCC) process includes coal gasification, with the gas from the coal passed through a gas turbine to generate electricity. The hot exhaust gas from the turbine heats water to produce steam to power a steam turbine and generate electricity a second time. The IGCC plant design results in relatively high initial capital costs; however, its improved efficiency and reduced emissions are expected to improve long-term profitability and educe the environmental impact. With prices for the primary alternative fuel, natural gas, roughly more than twice the norm, the economic outlook for new coal plants is positive.

A number of other proposed coal generating stations have received grants from the Department of Energy to support advanced coal technology projects. Excelsior Energy, Inc. and ConocoPhillips will receive a $38 million grant for the development of a new, 531-MW, IGCC plant to be located near Hoyt Lakes, Minnesota. Orlando Utilities Commission (OUC) and Southern Power, the unregulated subsidiary of Southern Company, will receive a $235 million grant for the development of a 285-MW, advanced coal plant to be built at OUC's existing Stanton Energy Center near Orlando, Florida. Peabody Energy will receive a $19.7 million grant to demonstrate a 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.
