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.

COVID-19 Simulation Results for ERCOT 2020 - a Comparison to Business as Usual Case

LCG, April 23, 2020 -- The COVID-19 pandemic is having a profound impact on daily life and the economy, from affecting which businesses are allowed to operate, to influencing international oil prices. States and major cities in the US are instituting quarantines, along with shelter-in-place directives, to contain the spread of COVID-19. Power markets will likely deviate from their business-as-usual scenario as a result of decline in power demand and fuel prices.

Both the business as usual (bau) and the COVID-case were simulated using UPLAN Net-Work Power model, and the main results are published in this report .The readers can download the the report directly.
