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.

Financing Obtained for Calpine's 600-MW Russell City Energy Center

LCG, June 28, 2011--Calpine Corporation announced yesterday that they have an $844.5 million credit facility to finance construction of the 619-MW, combined-cycle Russell City Energy Center. A Calpine affiliate owns 75% of Russell City and a GE Energy Financial Services affiliate owns the balance.

The new project finance facility includes a construction loan that will convert to a 10-year term loan when commercial operations commence. Construction started at the site in Hayward, California, and commercial operations are scheduled to commence in mid-2013. A ten-year, power purchase agreement (PPA) for the output from the plant is in place with Pacific Gas and Electric Company (PG&E), and PG&E will provide natural gas to the plant.

Calpine's President and Chief Executive Officer stated, "This financing marks an important milestone in our effort to bring much-needed electric power supply to California's Bay Area, allowing us to complete the construction of a modern, flexible, highly efficient, clean and low-carbon energy resource."

The Russell City Energy Center project began in 2001, but California's energy crisis and Calpine's subsequent financial challenges put the project on hold. In September 2007, the California Energy Commission (CEC) approved the natural gas-fired power plant project.
