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.

The Energy Information Administration (EIA) adopts UPLAN for potential integration with its Short Term Energy Outlook

LCG, October 8, 2014 – The office of Energy Information Administration (EIA) of the US Department of Energy has acquired UPLAN Network Power Model for specialized electric modeling. EIA has also acquired the accompanying Plants, Loads, Assets, Transmission and Operations (PLATO) data models for the entire US electric system.

UPLAN Network Power Model (UPLAN-NPM) developed by LCG Consulting of Los Altos, California, is a chronological electric grid model that is used to perform detail transmission, generation and economic analysis. The EIA staff plans to use UPLAN-NPM for scenario analysis, discussion papers and today-in-energy analysis, and to evaluate UPLAN-NPM forecasts for potential future incorporation in the Short Term Energy Outlook for electricity generation modeling.
