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.

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.

Southern Cancels IGCC Coal Plant in Florida
LCG, November 15, 2007--Southern Company announced yesterday that construction of an advanced, coal-fired power plant employing integrated gasification combined cycle (IGCC) technology was halted in Florida. With the cancelation of this plant, over 4,400 MW of planned coal-fired power generation facilities scheduled to be operational in Florida before 2014 have been terminated this year.
The decision to stop construction was made by an executive committee composed of representatives from the Orlando Utilities Commission (OUC) and Southern Power, a subsidiary of Southern Company. According to Southern Company, the decision was driven by continuing uncertainty surrounding potential state regulations relating to greenhouse gas emissions.
The new unit was to be installed near Orlando, Florida at the existing Stanton Energy Center owned by OUC. The IGCC plant is co-owned by Southern Power Company (the unregulated subsidiary of Southern Company), OUC, and Kellogg, Brown and Root. The plan had been for Southern Power to operate the plant, with commercial operation to commence in June 2010.
The facility would have used an IGCC technology based on the Transport Integrated Gasification (TRIG) technology that Southern Company and others have been developing at the Power Systems Development Facility near Wilsonville, Alabama.
The installation of a gas-fired combined cycle generating facility at Stanton Energy Center will proceed as previously planned.
The IGCC project is one of three demonstration projects that had received funding through the federal Clean Coal Power Initiative (CCPI), a 10-year, $2-billion demonstration program designed to improve the environmental performance of coal-fired power plants in the United States. The Department of Energy (DOE) was to provide a $235 million federal grant for the development of the advanced coal plant.
Southern's canceled plans follow the path of other coal-fired projects in Florida. Since taking office in January 2007, Florida Governor Charlie Crist has raised concerns regarding the threat of climate change and the use of fossil fuels, specifically coal.
In June, the Florida Public Service Commission (FPSC) reached a decision to not approve the two, 980-MW, coal-fired plants proposed by Florida Power and Light in Glades County.
In July, a group of community-owned, power entities (Florida Municipal Power Agency (FMPA), JEA, Reedy Creek Improvement District, and the City of Tallahassee) suspended permitting activities for the Taylor Energy Center, an 800-MW, coal-fired power plant proposed to be built in Taylor County, Florida. Tampa Electric, the principal subsidiary of TECO Energy, also announced in July that it will cancel plans to construct the proposed 632-MW, coal-fired Polk Unit 6 in Florida.
In August, a 750-MW, coal-fired plant proposed by Seminole Electric Cooperative and approved by the FPSC was denied a site certification by the Florida Department of Environmental Protection (FDEP). In total, over 4,400 MW of planned, coal-fired power generation facilities scheduled to commence generating power in Florida before 2014 have been terminated this year.
