NuScale Power Achieves Standard Design Approval from NRC for 77 MW SMR

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.

EIA Presents Analysis of California's Solar and Wind Power Curtailment Challenges

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.

Duke Submits COL Application for New Nuclear Power Station

LCG, December 14, 2007--Duke Energy yesterday submitted a combined construction and operating license (COL) application to the Nuclear Regulatory Commission (NRC) for the William States Lee III Nuclear Station. The new generating capacity is needed to meet Duke Energy Carolina's forecast growth in electric demands.

Unlike most plans to construct nuclear reactors in the United States, Duke proposes to build the two reactors at a greenfield site, rather than to add new capacity at an existing nuclear power station. The site is located in Cherokee County, South Carolina.

Duke selected Westinghouse Electric's AP1000 design for the William States Lee III Nuclear Station. The AP1000 design incorporates passive safety features. The NRC approved the Design Certification on December 30, 2005. The proposed two units will have a combined electric generating capacity of 2,234 MW.

Duke's COL application relies upon the COL application submitted October 31, 2007 to the NRC by the Tennessee Valley Authority (TVA) and NuStart Energy, a consortium of nuclear energy companies, to build two nuclear reactors at TVA's Bellefonte site in northern Alabama. 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.
