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 Announces Another Joint Development Project for New Nuclear Reactors
LCG, March 16, 2006--Southern Company (Southern) today announced that it has executed an agreement with Duke Power (Duke) to jointly pursue the development of a new nuclear power plant at a site in Cherokee County, South Carolina. Duke will be the developer and plant operator, and Southern will be a co-owner of the plant.
Duke had previously announced plans to pursue the development of a new nuclear plant, but the site had not been identified. Now Duke plans to proceed to prepare an application to the Nuclear Regulatory Commission (NRC) for a combined construction and operating license (COL) for two Westinghouse AP1000 reactors to be built at the Cherokee County site. The COL is scheduled to be submitted to the NRC by early 2008.
Last week Southern announced another joint proposal with Tennessee Valley Authority (TVA) whereby the two companies would jointly pursue the construction of two new nuclear reactors at TVA's Bellefonte plant site near Scottsboro, Alabama. The Bellefonte plant would also incorporate the AP1000 design, which includes a generating capacity of approximately 1,100 MW. Similarly, Southern has selected the AP1000 for two new reactors at its existing Plant Vogtle, located in Georgia.
The AP1000 reactor incorporates passive safety features that rely upon natural forces. The NRC approved the Design Certification for the AP1000 standard nuclear plant design on December 30, 2005. Since receiving NRC approval, the AP1000 is leading other reactor vendors and has also been selected by Progress Carolinas, SCANA and Santee Cooper as the basis for additional COL applications to construct new nuclear reactors.
Duke continues to evaluate the preparation of early site permit (ESP) applications for locations in Oconee County, S.C., and Davie County, North Carolina.
