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.

FirstEnergy Pursues State Legislation to Support Nuclear Plants in Ohio

LCG, February 24, 2017--FirstEnergy Corp. is pursuing legislation in Ohio to provide financial support to its two nuclear power plants, Davis-Besse and Perry, through a zero emission credits (ZECs) program. The financial support is sought to avoid premature retirement of the carbon-free electric generating facilities that have a combined capacity of 2,176 MW.

On Wednesday, FirstEnergy's president and chief executive officer stated, "We continue to assess and evaluate a number of strategic alternatives for our companies - for our competitive business, including asset sales, legislative or regulatory initiatives for generation that recognizes environmental or energy security benefits, alternatives for our retail business and financial restructuring."

Last year, state legislation with ZEC programs was passed in Illinois and New York to provide financial support and avoid early retirement of nuclear plants located in those states. The nuclear power plants are challenged to compete in a market with a growing number of combined-cycle plants fueled by low-cost natural gas. Furthermore, aggressive state renewable portfolio standards drive significant new installations of wind and solar capacity that reduce the net electricity load and dampen wholesale power prices. The New York Clean Energy Plan goal is 50 percent renewable energy by 2030, and the Illinois Renewables Portfolio Standard goal is 25 percent for 2026. In addition to providing clean energy with no carbon dioxide or other air emissions, the number of employees at the nuclear plants and the associated plant property taxes are a significant benefit to the counties in which the plants are located.
