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.

PSC Approves Plan to Construct Two Nuclear Units in South Carolina
LCG, February 12, 2009--The Public Service Commission (PSC) of South Carolina yesterday voted unanimously to approve the application of South Carolina Electric & Gas Company (SCE&G) to construct two additional nuclear reactors at the V.C. Summer Nuclear Station in South Carolina. The first unit is scheduled to commence operations in 2016, with operations of the second unit following in 2019.
The nuclear expansion project is a joint project between SCE&G, the principal subsidiary of SCANA Corp., and state-operated Santee Cooper. SCE&G will hold a 55 percent share, with Santee Cooper holding the remaining 45 percent. SCE&G will operate the two new, 1,117-MW units.
SCE&G and Santee Cooper jointly own the existing 966-MW V.C. Summer plant, and SCE&G is the plant operator. Commercial operations of the existing facility began in January 1984.
The PSC allowed SCE&G to start implementing a rate increase to cover some of the costs to finance the project, given SCE&G shows that the project is on schedule and that expenditures are within limits set in the Commission?s order. The estimated project cost to build both units, excluding the cost to finance and the cost for transmission upgrades, is $9.8 billion.
In May 2008, Santee Cooper and SCE&G announced a contractual agreement with Westinghouse Electric Company, LLC, and Stone & Webster, a subsidiary of The Shaw Group Inc., for the design and construction of the two units.
Approval from the Nuclear Regulatory Commission (NRC) is necessary before construction can begin, and that decision is not expected until late 2011 or early 2012. Santee Cooper and SCE&G submitted an application with the NRC in March 2008 for a combined construction and operating license (COL).
