WASHINGTON, Oct. 25 -- Carrie Fosaaen, acting vice president for regulatory affairs at NuScale Power LLC, Corvallis, Oregon, has issued a public comment on the Nuclear Regulatory Commission proposed rule entitled "NuScale Small Modular Reactor Design Certification".

In Reference 1, the U.S. Nuclear Regulatory Commission (NRC) issued for public comment the proposed rule to certify the NuScale standard design. In Reference 2, the NRC extended the comment period to October 14, 2021.

On behalf of NuScale Power, LLC (NuScale), I commend the NRC Staff for their efforts in reviewing the NuScale design certification application, issuing the NuScale Standard Design Approval (Reference 3), and promulgating this rule. This design certification is the culmination of NRC's comprehensive safety review, which involved over a quarter million review hours, about two million pages of documentation available for review or audit, and about 100 gigabytes of test data. NRC Staff thoroughly examined the design's innovative and robust safety features and addressed numerous regulatory, policy, and technical issues associated with the design and its licensing basis.

In an effort to clarify the final rule for NuScale, other potential users, and interested members of the public, NuScale has developed the comments attached to this letter for your consideration.
