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.

Governor Expands California Solar Roofs Plan

LCG, August 23, 2006--California Governor Schwarzenegger yesterday signed legislation to expand the California Solar Initiative. The plan is designed to result in one million solar roofs in California by 2018.

In January 2006, the California Public Utilities Commission (CPUC) approved the California Solar Initiative (CSI), a program designed to provide approximately $2.8 billion in incentives to spur development of approximately 3,000 MW of solar electric generating capacity over the period from 2006 through 2016.

With the Governor's approval yesterday of SB 1, elements of the Million Solar Roofs plan that the CPUC does not have the authority to mandate can now be implemented. For example, the plan will no longer by limited to Pacific Gas and Electric, Southern California Edison and San Diego Gas and Electric - the utilities regulated by the CPUC - but will be expanded to include the municipal-owned utilities, including the Los Angeles Department of Water and Power (LADWP) and the Sacramento Municipal Utilities Division (SMUD).

The new legislation will also increase the number of consumers that can sell surplus electricity back to the utilities by a factor of five (from 0.5 percent to 2.5 percent).

Another key element of SB 1 is that, commencing January 2011, it will require a developer of more than 50 new single family homes to offer a solar energy system alternative to all customers.
