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 Power Purchase Bonds Closer to Reality

LCG, Feb. 1, 2002-The California Public Utility Commission appears ready to issue a plan for the state to issue $12.5 billion of revenue bonds to repay California for purchases of electricity made on behalf of investor-owned utilities.

A vote on by the full PUC on the proposal is expected by Feb. 21. The major issue surrounding such bonds concerns how much of the revenue from ratepayers' electricity purchases would go to the Department of Water Resources, which made purchases of power beginning last year, and how much would be used to repay bondholders. Despite some opposition from consumer groups to the prices at which power has been purchased, a draft "rate agreement" was welcomed by Gov. Davis, who called it "a significant step in the right direction to get energy bonds sold."

State Treasurer Phil Angelides' office had no comment yesterday, but said in a statement that passage of a bond measure would involve numerous hurdles. Angelides had been disappointed in October of last year when Loretta Lynch, head of the PUC, would not approve a rate agreement in October because she considered the long-term contracts with suppliers to be too expensive.

The revised plan calls for "best efforts" by the DWR to gain better terms for the long-term purchases. Nettie Hoge, of the Utility Reform Network, said the plan "takes all these overcharges and gives them phony names. Nobody is going to be able to understand anything about what the bill means."

PUC commissioner Richard Bilas noted that although the new plan is a step away from the PUC's earlier position, "we're getting precariously close to the point where if we don't issue bonds pretty soon the state's going to be in very serious trouble."
