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.

MidAmerican Completes Wind Projects in Iowa

LCG, December 15, 2005--MidAmerican Energy announced that it has completed the installation of all 257 wind turbines at two wind farm projects in Iowa. The combined electric generating capacity of the two projects is 360.5 MW.

The new wind farms are located in northwest Iowa in Sac and Buena Vista counties and in north central Iowa in Wright and Hamilton counties. The final wind turbine was commissioned on Tuesday at the Intrepid site in northwest Iowa, and the final turbine at the Century site in north central Iowa was commissioned on November 30.

The initial plan was to install 310.5 MW of capacity, and this phase was completed in September. An additional 50 MW of capacity was approved by the Iowa Utilities Board in January 2005 and is now installed and operational.

MidAmerican announced its final plans to proceed with the projects in September of last year, following the approval of the Production Tax Credit by the House and Senate. The Production Tax Credit, which provides for 1.5 cents for each kilowatt-hour of electricity produced, had expired at the end of 2003. When the credit expired, the financial viability of wind projects was significantly reduced, and many projects were put on hold.
