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.

NRG Files with NRC to Construct New Nuclear Reactors in Texas
LCG, September 25, 2007--NRG Energy, Inc. (NRG) and South Texas Project Nuclear Operating Company (STPNOC) yesterday announced that they will file a Combined Construction and Operating License (COL) Application with the Nuclear Regulatory Commission (NRC) to construct and operate two new nuclear units at the South Texas Project, located about 90 miles southwest of Houston. NRG expects the new units to commence operations in 2014 and 2015.
The combined design capacity of the new units will equal or exceed 2,700 MW. The existing two units are pressurized water reactors, each with a capacity of 1,312 MW. NRG selected the Advanced Boiling Water Reactor (ABWR) technology for the new units. The NRC issued final design certification for the GE ABWR in 1997, allowing it to be used in U.S. projects. The ABWR is a "Generation III" reactor design that is in operation today, with four operating units in Japan and three more approaching completion in Taiwan and Japan.
STPNOC, together with a contracting team led by GE-Hitachi Nuclear Energy and Bechtel, prepared the COL application that was to be filed yesterday. The COL application includes two key components: a safety analysis and an environmental report. NRG anticipates that the NRC process will lead to NRG receiving its license approval such that it could commence construction in 2010.
The site and cooling reservoir were originally designed for four units, and the plans are for the new units to be built adjacent to the existing two units. STPNOC, which currently operates units 1 and 2, will operate the new units.
NRG owns 44 percent of the South Texas Project, and CPS Energy and Austin Energy own 40 percent and 16 percent, respectively. The nuclear expansion is part of NRG's corporate strategy to increase non-carbon emitting generation and reduce its carbon intensity.
