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.

Florida PSC Approves Agreement for New Biomass Plant in Florida

LCG, August 17, 2006--The Florida Public Service Commission (PSC) approved on Tuesday a petition for Progress Energy Florida (Progress) to buy energy produced by the Florida Biomass Energy Group, LLC (Florida Biomass) at a proposed 116-MW biomass plant located near Lake Okeechobee. The plant is scheduled to commence operations no later than December 2009.

The Florida PSC recently certified Florida Biomass as a qualifying facility (QF) based on the exclusive use of renewable energy, after start-up, for the proposed electric generation.

The renewable fuel for the proposed plant is a bamboo-like grass known as E-grass. The energy crop would be harvested at the 15,000 acre site and processed into a liquid fuel using a pyrolysis process. The plant will use combustion turbine-combined cycle technology, and the thermal fuel input will include combustible exhaust gases from the pyrolysis process.

When the negotiated contract was compared to a gas-fired, combined cycle alternative, Progress estimated the capacity and energy payments over the 25-year term of the negotiated contract would produce a savings of $39 million net present value to Progress's ratepayers. The majority of such savings are based on fuel costs.
