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.

Mississippi Power Proceeds with Another Solar PV Project

LCG, April 28, 2016--Southern Company subsidiary Mississippi Power and Silicon Ranch Corporation held a groundbreaking ceremony for the state's largest solar farm yesterday in Hattiesburg. The 50-MW solar PV project is estimated to cost $100 million and is scheduled to commence operations by early 2017.

The Hattiesburg solar farm will be installed on 450 acres and will include over 600,000 solar panels. Silicon Ranch will fund, own and operate the project and has selected Strata Solar to build it. Mississippi Power will receive all of the energy and associated renewable energy credits (RECs) generated by the project. The power will be purchased through a 25-year power purchase agreement (PPA).

Mississippi Power President and CEO stated, "This is the second of three major solar projects that have been approved by the Public Service Commission, demonstrating Mississippi Power's continuing commitment to cost-effective solar development. The Pine Belt region is one of the hubs of economic development in the state and our investments in renewable energy here will contribute to future growth."

In May, Mississippi Power and Origis Energy will break ground on a 52-MW utility-scale solar project in Sumrall. Last month, Mississippi Power, the U.S. Navy and Hannah Solar broke ground on a 3-4 MW solar project at the Naval Construction Battalion Center in Gulfport, Mississippi.
