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.

DOE Award on Dynamic Simulation Tools and Measurement-Based Control



LCG, Sept. 20, 2012 - LCG Consulting (LCG) of Los Altos, California, is a part of the consortium organized by Michigan State University, which is recently awarded a $1.5 million grant by the Office of Electricity Delivery and Energy Reliability under DOE Advanced Modeling Grid Research Program.

The project team -- Michigan State University, University of Illinois-Chicago, Florida State University Center for Advanced Power Systems, Los Alamos National Laboratory, Southern California Edison, and LCG Consulting -- will develop a Lyapunov function based remedial action screening (L-RAS) tool that uses real-time data. This approach is expected to supports selection of appropriate remedial actions that are most likely to result in stabilizing trajectories.

For this project, LCG Consulting will provide high level advisory services in the areas of electric system modeling, develop and implement a user interface to L-RAS as well as develop and run scenarios using its proprietary UPLAN models to support the team modeling efforts.

The DOE Advanced Modeling Grid Research Program leverages scientific research in mathematics for application to power system models and software tools. It is envisioned that the selected projects will result in a new class of decision support tools that will simulate dynamic events and help inform operators on real-time conditions to maintain stability.
