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 Files for New IGCC Project in Indiana

LCG, September 8, 2006--Duke Energy Indiana and Vectren Energy Delivery of Indiana have filed an application for "Certificates of Public Convenience and Necessity" (CPCN) with the Indiana Utility Regulatory Commission to build a coal-fired, electric generating station that would employ an integrated gasification combined cycle (IGCC) design.

The proposed project would have a capacity of approximately 630 MW and would be built at Duke'sexisting Edwardsport generating station near Vincennes, Indiana. Once the new plant is operational, the old facilities, which include coal and oil units that have a capacity of 160-MW, would be retired.

The IGCC design includes coal gasification, with the gas created 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 gasification process offers the potential for lower cost solutions to capture and sequester CO2.

Duke and Vectren have commissioned GE Energy and Bechtel Corporation to develop an engineering and design study for the plant, which is expected to be completed by the second quarter of 2007. Given favorable plant economics and regulatory review, construction could commence as early as mid-2007.

The application with the Commission is another positive step forward for this project. In September of last year, Cinergy - which was acquired by Duke - announced that it would start the preliminary engineering and design of an IGCC generating station in partnership with Vectren Corporation and that they planned to use GE Energy and Bechtel Corporation for the preliminary engineering study.
