(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.

A Note on Ric Teague, Founding Editor

EnergyOnline Daily News has been informed, enlivened, and enriched by Founding Editor Ric Teague since March 1996, but as of the third week of January, Ric has been forced to step back from his day-to-day involvement with EnergyOnline in order to focus on mounting medical problems.

Ric is a long-time resident of the San Francisco Bay Area, a graduate of Stanford University (former Managing Editor, The Stanford Daily), a holder of degrees in journalism and business, a veteran of the Korean War, a professional musician, an artist, a management consultant and an aviator, but those few details do not begin to convey his wealth of experience as a man of the world. His interests have carried him far. Most recently, he published a compendium of U.S. naval history covering the past two-hundred years.

He is an expert on matters lingual, historical, rhetorical, mechanical, and practical, as well as delightfully trivial. He is incisive and direct, and a master of refinement and etiquette. Ric is the embodiment of dedication, valor, professionalism, and willpower.

We will miss Rics presence, his spirit and his humor at LCG, and our thoughts are with him in his present situation.
