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.

Georgia PSC Approves Georgia Power's 2019 IRP

LCG, July 18, 2019--The Georgia Public Service Commission (PSC) has unanimously approved Southern Company subsidiary Georgia Power's 2019 Integrated Resource Plan (IRP), which was submitted in late January.

The approved IRP calls for Georgia Power to retire five coal-fired units: Plant Hammond Units 1-4 near Rome, Georgia, and Plant McIntosh Unit 1 near Rincon, Georgia. The combined capacity of these coal units is approximately 980 MW. The company also will not renew its operating licenses for three small hydro plants: Estatoah, Langdale and Riverview.

Georgia Power had initially recommended adding 1,000 MW of renewable energy. In a stipulation agreement with Commission staff, that amount was increased to 1,650 MW. During Tuesday's hearing, the PSC Chairman made a motion to increase the renewable/solar energy procurement to 2,210 MW, the largest increase in renewable energy in Georgia's history. The five-member Commission voted unanimously for Chairman's motion. The final IRP decision also includes 50 MW of new competitively bid biomass generation (typically wood) was added.

"I determined Georgia has the ability to add significantly more renewable energy and solar energy using a market-based approach without any upward pressure on the rate payers and no state subsidies," the Chairman said.

The IRP calls for Georgia Power to own and operate 80 MW of battery energy storage systems (BESS), which will support the growth of intermittent or variable solar energy facilities and provide the company the opportunity to demonstrate the deployment, integration and operation of storage.

Georgia Power's senior vice president and senior production officer stated, "Working with the Georgia PSC, we are positioning Georgia as a leader in the Southeast in battery energy storage, which is critical to growing and maximizing the value of renewable energy for customers as we increase our renewable generation by 72 percent by 2024. Through the IRP process, Georgia Power will continue to invest in a diverse energy portfolio including the development of renewable resources in a way that benefits all customers to deliver clean, safe, reliable energy at rates that are well below the national average."
