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.

Science Panel Recommends Gradual Approach at Yucca

LCG, Feb. 10, 2003--A group of scientific experts with the National Research Council issued a report, "One Step at a Time," which supports a gradual evolution of storage procedures for nuclear waste at Nevada's Yucca Mountain, as well as more research as storage commences.

The report said that the Department of Energy, which is moving towards many of the recommendations in the report, would need to build the support of stakeholders, such as authorities in Nevada, in order to make a more gradual storage plan work as intended. Nevada officials, such as Sen. Harry Reid, R-Nev., stated their view that the report's suggestion that more waste be stored aboveground was evidence that the Department of Energy's design for an underground repository was never fully formed.

"If there was an expectation from the get-go that this was going to be an experimental process and you do this on an ongoing basis, that might be one thing, but that's not the way the law was written," said Bob Loux, head of Nevada's Agency for Nuclear Projects. The report said that in order to avoid costly or harmful consequences of proceeding too fast with underground storage, a staging area bigger than the one first planned could be used to handle waste while smaller, preliminary tests were made with interring waste for several years. Loux said that more emphasis on the staging area contradicted licensing conditions and environmental statutes.

The report noted that those handling the waste in the "buffer storage" area, where shipments would first be repackaged and blended to manage heat release, could be subject to more radiation exposure if delays ran into the hundreds of years.
