The Nuclear Regulatory Commission has issued its final rule certifying NuScale Power’s small modular reactor design, making the Portland, Ore.–based company’s power module the first SMR design to be certified by the agency (and only the seventh reactor design okayed for use in the United States).

Published in yesterday’s Federal Register, the rule goes into effect on February 21, allowing utilities to reference the NuScale design when applying for a combined license to build and operate a reactor. The design will be incorporated as Appendix G to 10 CFR Part 52, Licenses, Certifications, and Approvals for Nuclear Power Plants.

As noted last July—when the commission voted unanimously to approve the design certification and directed staff to issue the final rule—an application for a nuclear power plant combined license that references a certified design does not need to address any of the issues resolved by the design certification rule. Instead, the combined license application and the NRC’s safety review would address any remaining safety and environmental issues for the proposed plant.

The Nuclear Regulatory Commission has directed its staff to issue a final rule certifying NuScale Power’s small modular reactor design for use in the United States, the agency announced last Friday.

Certification of the Portland, Ore.–based SMR developer’s design will become effective 30 days after publication of the rule in the Federal Register. The design will be incorporated as Appendix G to 10 CFR Part 52, Licenses, Certifications, and Approvals for Nuclear Power Plants.
