The Nuclear Regulatory Commission has accepted for formal review NuScale Power’s standard design approval (SDA) application for its updated small modular reactor design, the Portland, Ore.–based firm announced yesterday.

The Nuclear Regulatory Commission recently announced that it will begin reviewing most of the standard design approval (SDA) application for NuScale Power’s uprated small modular reactor technology, with the remainder of the review on hold until the company provides additional details on a key safety topic.

NuScale Power has announced its submission to the Nuclear Regulatory Commission of a standard design approval application for its updated small modular reactor design, which is based on a six-module VOYGR plant configuration powered by an uprated 77-MWe module.

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.
