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.

California Bond Sale Going Before PUC

LCG, Feb. 21, 2002--The California Public Utilities Commission will vote today on a bond measure worth $10.85 billion, to repay the state for power purchases made in the past year.

Last year, the bond sale was set by Gov. Davis at $13.4 billion, and then $12.5 billion, and in October was rejected by the PUC on the grounds that the price paid for power through long-term contracts had not been justified. In October, Gov. Davis' administration said that estimates of power costs paid by the state were 20% lower than what had been foreseen two months earlier.

California faces a projected budget deficit of $14 billion, with an additional $6.1 billion shortfall possible due to past power purchases made using the state's general fund. If the bonds are sold by June 30, the close of the states fiscal year, the purchases will not be added to the deficit.

In additional to the $6.1 billion, California also obtained a $4.1 billion loan for power purchases, which will incur $413 million in interest charges by the end of June. Criticism of the terms of the bond measure have focused on the fact that the PUC will not have the authority to approve the Department of Water Resources' power-related costs as stated by that agency.

Loretta Lynch, PUC's president, said "the law says the PUC shall cover DWR's cost, whatever they are. The reasonableness of their costs resides with them, not us."
