Project Overview

The staff of the U.S. Nuclear Regulatory Commission (NRC) is currently engaged in review activities of the NuScale small modular reactor (SMR) design certification application. NuScale is an integral pressurized-water reactor, designed by NuScale Power, LLC. The design is based on Multi-Application Small Light Water Reactor developed at Oregon State University in the early 2000s. NuScale is a natural circulation light water reactor with the reactor core and helical coil steam generators located in a common reactor vessel in a cylindrical steel containment. The reactor vessel containment module is submerged in water in the reactor building safety related pool, which is also the ultimate heat sink for the reactor. The pool portion of the reactor building is located below grade. The reactor building is designed to uphold 12 SMRs. Each NuScale SMR has a rated thermal output of 160 MWt and electrical output of 50 MWe, yielding a total capacity of 600 MWe for 12 SMRs.
