I. Background

On August 9, 2013 (78 FR 48727), the NRC staff issued the previously mentioned proposed revised SRP sections for public comment. The NRC staff received no comments on the proposed revisions. This guidance is being issued as final for use. There were no changes made to the guidance since it was issued for public comment. Details of specific changes between current SRP guidance and the final guidance being issued here are included at the end of each of the revised sections themselves, under the “Description of Changes” subsections.

II. Backfitting and Issue Finality

These SRP section revisions provide guidance to the staff for reviewing applications for a construction permit and an operating license under part 50 of Title 10 of the Code of Federal Regulations (10 CFR) with respect to designs of structures, components, equipment, and systems. The SRP also provides guidance for reviewing an application for a standard design approval, a standard design certification, a combined license, and a manufacturing license under 10 CFR Part 52 with respect to those same subject matters.

Issuance of these SRP section revisions does not constitute backfitting as defined in 10 CFR 50.109 (the Backfit Rule) nor is it inconsistent with the issue finality provisions in 10 CFR part 52. The NRC's position is based upon the following considerations.

1. The SRP Positions Would Not Constitute Backfitting, Inasmuch as the SRP Is Internal Guidance to NRC Staff

The SRP provides internal guidance to the NRC staff on how to review an application for NRC regulatory approval in the form of licensing. Changes in internal staff guidance are not matters for which either nuclear power plant applicants or licensees are protected under either the Backfit Rule or the issue finality provisions of 10 CFR part 52.

2. The NRC Staff Has No Intention To Impose the SRP Positions on Existing Licensees Either Now or in the Future

The NRC staff does not intend to impose or apply the positions described in the SRP to existing licenses and regulatory approvals. Hence, the issuance of this SRP—even if considered guidance within the purview of the issue finality provisions in 10 CFR part 52—does not need to be evaluated as if it were a backfit or as being inconsistent with issue finality provisions. If, in the future, the NRC staff seeks to impose a position in the SRP on holders of already-issued licenses in a manner that does not provide issue finality as described in the applicable issue finality provision, then the staff must make the showing as set forth in the Backfit Rule or address the criteria for avoiding issue finality as described in the applicable issue finality provision.

3. Backfitting and Issue Finality Do Not—With Limited Exceptions Not Applicable Here—Protect Current or Future Applicant

Applicants and potential applicants are not, with certain exceptions, protected by either the Backfit Rule or any issue finality provisions under 10 CFR part 52. Neither the Backfit Rule nor the issue finality provisions under 10 CFR part 52—with certain exclusions—were intended to apply to every NRC action that substantially changes the expectations of current and future applicants. The exceptions to the general principle are applicable whenever an applicant references a 10 CFR part 52 license (e.g., an early site permit) or NRC regulatory approval (e.g., a design certification rule) with specified issue finality provisions. The NRC staff does not, at this time, intend to impose the positions represented in the SRP in a manner that is inconsistent with any issue finality provisions. If, in the future, the staff seeks to impose a position in the SRP section in a manner that does not provide issue finality as described in the applicable issue finality provision, then the staff must address the criteria for avoiding issue finality as described in the applicable issue finality provision.

III. Congressional Review Act

This action is a rule as defined in the Congressional Review Act (5 U.S.C. 801-808). However, the Office of Management and Budget has not found it to be a major rule as defined in the Congressional Review Act.
