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.

LA City Council Votes to Approve Goal of 100% Carbon-free Energy by 2035

September 3, 2021--The Los Angeles City Council voted unanimously on Wednesday to direct the Los Angeles Department of Water and Power (LADWP) to prepare a Strategic Long Term Resource Plan that achieves 100 percent carbon-free energy by 2035. The target year of 2035 is ten years earlier than the prior target and aligns with the goals proposed by President Biden for the electric sector.

The approved motion also directs LADWP to report every six months on the transition to renewable energy to the City Council’s Energy, Climate Change, Environmental Justice and River Committee. In addition, the LADWP is ordered to develop a long-term hiring plan for nearly 10,000 “green” jobs.

LADWP, the largest municipal utility in the country, has been planning for carbon-free power, and the new motion will accelerate their efforts.

LADWP is actively working to develop a new power generating facility at the Intermountain Power Plant (IPP) in Delta, Utah, where the current coal-powered facility will be retired. The new combined-cycle facility will use advanced gas turbines fueled with a hydrogen-gas mix and, ultimately, 100 percent renewable hydrogen for power generation. The project includes the development of nearby salt caverns for underground storage of green hydrogen. The facility will be owned by the Intermountain Power Agency (IPA) and operated by LADWP.
