LCG, May 30, 2025--NuScale Power Corporation (NuScale), a leading provider of advanced small modular reactor (SMR) nuclear technology, yesterday announced that it has received design approval from the U.S. Nuclear Regulatory Commission (NRC) for its uprated 77 MW power modules. NuScale states that it remains the only SMR technology company with design approval from the NRC, and the company remains on track for deployment by 2030, with 50- and 77-MW SMR options.

LCG, May 29, 2025--The U.S. Energy Information Administration (EIA) released an analysis yesterday showing that the California Independent System Operator (CAISO), the grid operator for most of the state, is increasing its curtailment of the rapidly growing solar- and wind-powered generation facilities in order to balance electricity supply and demand, which is necessary to maintain a stable electric system.

Cost Estimate Up for Duke's New Nuclear Power Station
LCG, November 5, 2008--Duke Energy Carolinas informed the North Carolina Utilities Commission that the estimated cost to build the proposed William States Lee, III Nuclear Station in South Carolina has risen to $11 billion, or approximately double the original estimate, excluding financing. The new power plant is scheduled to be operational in 2018 in order to meet Duke Energy Carolina's forecast growth in electric demands.
Duke proposes to install two 1,117-MW reactors and to use Westinghouse Electric's AP1000 design, which incorporates passive safety features. The Nuclear Regulatory Commission (NRC) approved the Design Certification on December 30, 2005.
Last February Duke received notification from the NRC that the combined construction and operating license (COL) application for Lee Nuclear Station submitted December 2007 was accepted and docketed.
Duke's COL application relies upon the COL application to build two nuclear reactors at TVA's Bellefonte site in northern Alabama that was submitted October 31, 2007 to the NRC by the Tennessee Valley Authority (TVA) and NuStart Energy, a consortium of nuclear energy companies that includes Duke.
Other companies that have announced the selection of the AP1000 design as the basis for additional COL applications to construct reactors include Progress Energy, Southern Company, SCANA and Santee Cooper.
Duke's proposal is relatively unique for the United States in that Duke plans to build the reactors at a greenfield site, rather than to add capacity at an existing nuclear power station. The greenfield site is located in Cherokee County, South Carolina.
