NuScale’s SMR design clears Phase 4 of Nuclear Regulatory Commission’s review process

NuScale Power announced that the US Nuclear Regulatory Commission (NRC) has completed the fourth phase of review of the design certification application (DCA) for the company’s 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.

NuScale’s technology is the world’s first and only SMR to undergo design certification review by the NRC. The announcement, along with ongoing work by NuScale’s manufacturing partners, demonstrates how close NuScale is to bringing the US’ first SMR into production and operation, putting the US on the path to beat foreign competitors in the global SMR race.

NuScale said that the achievement is a result of the successful private-public partnership with the US Department of Energy and support from Congress.

Phase 4 of the NRC’s DCA review represents 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, and the NRC remains on track to complete its final review of NuScale’s design by this date. The Final SER represents approval by the NRC staff of the design.

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

We appreciate the NRC’s efforts to streamline Phase 5, and we expect that Phase 5 will be completed on or ahead of the original schedule in June 2020. Phase 6 is preparation of the Final SER, which will incorporate confirmatory items from the Phase 4 advanced SER, and comments raised by ACRS in Phase 5.

As NuScale’s first customer, the Utah Associated Municipal Power Systems is planning a 12-module SMR plant in Idaho slated for operation by the mid-2020s based on the NRC’s certified design.

In preparation for its first SMR plant in the US, NuScale has also signed MOUs to explore the deployment of its technology in Canada, Jordan, the Czech Republic, and Romania, and similar agreements are being discussed with other potential customers.

NuScale has also taken steps to build out its supply chain in the past year, signing preliminary agreements with companies that will offer technical expertise and will manufacture various components of the reactor. The most recent of these include Doosan Heavy Industries and Construction, Ltd. and Sargent and Lundy, both of which provided a cash investment in NuScale.

The majority investor in NuScale is Fluor Corporation, a global engineering, procurement, and construction company with a 60-year history in commercial nuclear power.



This is good news. I hope that this keeps going smoothly as it represents one of the best chances for new reliable base zero emission power.

Real gems

yes, we totally agree with this concept of NRC because the National Register of Citizens is the register which contains the names of the Indian citizens. At present, Assam is the only state having such a Register.and after that the govt. of India applied this concept to whole Indian citizens.
