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.

NRC Accepts MHI's Nuclear Reactor Design Application for Review

LCG, March 5, 2008--The Nuclear Regulatory Commission (NRC) on February 29 accepted for review an application from Mitsubishi Heavy Industries (MHI) to certify the U.S. Advanced Pressurized Water Reactor (US-APWR) design. The US-APWR design supports a 1,700 MW nuclear power station design. A similar version is now under license review in Japan.

MHI filed its application to certify the design on December 31, 2007. The NRC will conduct a technical review and will issue a Safety Evaluation Report after all technical and safety questions are addressed. The NRC may then certify the design with an agency rulemaking. The NRC?s Office of New Reactors expects the review work will continue at least into 2011.

Given certification by the NRC, a company applying for a license to construct and operate a nuclear power plant could elect to use the design and reduce potential litigation, as safety issues resolved within the scope of the design certification would generally not be subject to litigation.

The US-APWR design was selected by Luminant (formerly TXU Power) for its planned new nuclear power plants, which include two new reactors at the existing, 2,300-MW Comanche Peak nuclear power station in Texas.
