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 Energy Carolinas Files IRP

LCG, September 6, 2018--Duke Energy Carolinas excluded new nuclear construction in its recently filed Integrated Resource Plan (IRP), which includes its 15-year plan for new power generation.

For many years, expansion of nuclear generation has been a normal part of Duke's solution to meeting long-term electric supply needs. However, new nuclear reactors are not part of the new IRP. However, new nuclear projects remain a possibility for the future. Duke continues to monitor developments in advanced nuclear reactors and small modular reactors (SMRs).

Duke does plan to pursue receiving license extensions for its existing nuclear assets, which total 7,400 MW of capacity. The Nuclear Regulatory Commission (NRC) has historically issued 40-year licenses for the initial reactor operating period, with 20-year extensions available to units that qualify. All of Duke's nuclear units have received the first, 20-year extensions, which allow for a 60-year life. The next step a number of companies, including Duke, are considering with the NRC is to extend the licenses for another 20 years, or a total of 80 years. If the existing carbon-free nuclear plants can receive an additional 20 years of operations, then there will be significant benefits with respect to limiting carbon emissions.
