II. Further Information

The Office of New Reactors and Office of Nuclear Reactor Regulation proposes to revise Sections 2.5.1 through 2.5.5 in Chapter 2 of NUREG-0800, “Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR Edition.

The proposed changes to the SRP sections reflect the current staff review methods and practices based on lessons learned from NRC reviews of design certification and combined license applications completed since the last revision of this chapter. Changes include: (1) incorporating several guidance documents including Interim Staff Guidance DC/ISG 017, “Interim Staff Guidance on Ensuring Hazard-Consistent Seismic Input for Site Response and Soil Structure Interaction Analyses,” NUREG-2115 and NUREG-2117; (2) adding information concerning the Geologic Mapping License Condition; (3) adding specification for backfill Inspections, Tests, Analyses, and Acceptance Criteria for backfill to be placed under safety related structures; (4) adding references to, or clarified the acceptance criteria with respect to Appendix S of Title 10 of the Code of Federal Regulations (10 CFR) parts 50 and 52, 10 CFR 100.23(d)(2), 100.23(c), 52.17, C 52.79 and GDC 2; and (5) clarifying and strengthening the review interface between various SRP Sections.

The NRC requests public comments on the proposed revisions to the five SRP sections in Chapter 2. After the NRC considers any public comments, it will make a determination regarding the issuance of the five proposed SRP Sections in final form.

Backfitting and Issue Finality

The five draft SRP sections, if finalized, would provide guidance to the staff with respect to site characteristics and parameters when reviewing future applications for construction permits and operating licenses under 10 CFR part 50, and future applications for early site permits, standard design approvals, standard design certifications, and combined licenses under 10 CFR part 52 with respect to those same subject matters. The NRC staff does not intend to impose the positions in the draft SRP sections, if finalized, on the two existing OL applications, the current applications for design certification rules, the current applications for early site permits, the two current holders of combined licenses, or the current applications for combined licenses.

Issuance of these draft SRP sections, if finalized, would not constitute backfitting as defined in 10 CFR 50.109, or otherwise be inconsistent with the issue finality provisions in 10 CFR part 52. The staff's position is based upon the following considerations.

1. The draft SRP positions, if finalized, do not constitute backfitting, inasmuch as the SRP is internal guidance to NRC staff.

The SRP provides interim guidance to the 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 applicants or licensees are protected under 10 CFR 50.109 or issue finality provisions in 10 CFR part 52.

2. Backfitting and issue finality—with certain exceptions discussed below—do not protect current or future applicants.

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. This is because neither the Backfit Rule nor the issue finality provisions under 10 CFR part 52—with certain exclusions discussed below—were intended to apply to every NRC action which 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) and/or NRC regulatory approval (e.g., a design certification rule) with specified issue finality provisions. The staff does not, at this time, intend to impose the positions represented in the draft SRP section (if finalized) in a manner that is inconsistent with any issue finality provisions. If, in the future, the staff seeks to impose a position in the draft SRP section (if finalized) in a manner which 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.

3. The staff has no intention to impose the draft SRP positions on existing nuclear power plant licenses or regulatory approvals either now or in the future (absent a voluntary request for change from the licensee, holder of a regulatory approval, or a design certification applicant)

The staff does not intend to impose or apply the positions described in the draft SRP section to existing (already issued) licenses (e.g., operating licenses and combined licenses) and regulatory approvals—in this case, design certifications. Hence, the draft SRP—even if considered guidance which is within the purview of the issue finality provisions in 10 CFR part 52—need not be evaluated as if it were a backfit or as being inconsistent with issue finality provisions. If, in the future, the staff seeks to impose a position in the draft SRP (if finalized) on holders of already issued licenses in a manner which 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 applicable issue finality provision, as applicable.

The NRC staff is issuing this notice to solicit public comments on the proposed SRP Sections in Chapter 2. After the NRC staff considers any public comments, it will make a determination regarding the proposed SRP Sections in Chapter 2.
