NRC completes Phase 4 of DCA review of NuScale’s SMR

15 January 2020

NuScale Power recently announced that the U.S. Nuclear Regulatory Commission (NRC) has completed the fourth phase of review of the design certification application (DCA) for the company’s revolutionary small modular reactor (SMR). NuScale reached this milestone on schedule, marking yet another significant achievement along its path to commercialization. The entire review of NuScale’s SMR design is now in Phases 5 and 6.

Phase 4 of the NRC’s DCA review represents the completion of the advanced safety evaluation report (SER) with no open items. Completion of Phase 4 is significant as it signifies near-completion of the technical review. All requests for additional information have been closed, and all open items have been closed. This is the last version of the SER before the NRC issues its Final SER in September 2020. The Final SER represents approval by the NRC staff.

Phases 5 and 6 of the NRC review remain. Phase 5 entails a review by the NRC’s Advisory Committee on Reactor Safeguards (ACRS) that reviews and reports on safety studies and reactor facility license and license renewal applications.
