Project Overview

The staff of the U.S. Nuclear Regulatory Commission (NRC) is currently engaged in pre-application activities on the NuScale small modular reactor (SMR) design. NuScale is an integral pressurized-water reactor (iPWR), designed by NuScale Power, LLC. The design is based on MASLWR (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 generator 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. The reactor building is located below grade. The reactor building is designed to hold 12 SMRs. Each NuScale SMR has a rated thermal output of 160 MWt and electrical output of 45 MWe, yielding a total capacity of 540 MWe for 12 SMRs.
