The staff of the U.S. Nuclear Regulatory Commission (NRC) is currently engaged in pre-application activities for NuScale720 small modular reactor (SMR) standard design approval application. NuScale720 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. NuScale720 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 NuScale720 SMR has a rated thermal output of 200 MWt and electrical output of 60 MWe, yielding a total capacity of 720 MWe for 12 SMRs.
