NuScale Power Corporation is a publicly traded American company that designs and markets small modular reactors. It is headquartered in Portland, Oregon. A 50 MWe version of the design was certified by the US Nuclear Regulatory Commission in January 2023. The current scalable 77 MWe SMR VOYGR design was submitted for NRC review on January 1, 2023, and as of December 2023 was about a third complete. NuScale's SMR designs employ 9 feet diameter by 65 feet high reactor vessels that use conventional cooling methods and run on low enriched uranium fuel assemblies based on existing light water reactor designs. Each module is intended to be kept in an underground pool and is expected to produce about 77 megawatts of electricity. Its coolant loop uses natural convection, fed from a large water reservoir that can operate without powered pumps. NuScale had agreements to build reactors in Idaho by 2030, but this was cancelled in 2023 due to the estimated cost having increased from $3.6 billion to $9.3 billion for a 460 MWe power plant.
