NuScale Power Corporation is a publicly traded American company that designs and markets small modular reactors. It is headquartered in Tigard, Oregon. The company's VOYGR-4, a scalable 308 MWe version of the design, was certified by the US Nuclear Regulatory Commission in January 2023. The current VOYGR-6 design, a scalable 462 MWe SMR, was submitted for NRC review on January 1, 2023, and was approved on May 29, 2025. NuScale is now seeking NRC approval for their 12-module VOYGR-12. The SMR is also scalable, offering up to 924. 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. Individual NuScale Power Modules are intended to be kept in an underground pool and each are 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. Wikipedia
