SUPPLEMENTARY INFORMATION:

I. Introduction

The NRC is issuing a revision to an existing guide in the NRC's “Regulatory Guide” series. This series was developed to describe and make available to the public information such as methods that are acceptable to the NRC staff for implementing specific parts of the NRC's regulations, techniques that the staff uses in evaluating specific problems or postulated accidents, and data that the staff needs in its review of applications for permits and licenses. This regulatory guide is a rule as designated in the Congressional Review Act (5 U.S.C. 801-808). However, the Office of Management and Budget (OMB) has not found it to be a major rule as designated in the Congressional Review Act.

II. Further Information

This guide describes the general scope and depth that the NRC staff considers acceptable for ITPs for light water cooled nuclear power plants. This RG is being revised to address design qualification tests for new design certifications (DCs) and combined licenses (COLs) using the requirements in part 52 of Title 10 of the Code of Federal Regulations (10 CFR), “Licenses, Certifications, and Approvals for Nuclear Power Plants.” This RG is also being revised to add some preoperational, low-power and power ascension tests for new light water reactors (LWRs) licensed under 10 CFR Part 52. In addition, this RG is being revised to add new and updated references.

The RG has 3 appendices. Appendix A addresses the specific tests recommended or required for the ITPs. Appendix B provides information about ITP-related inspections that the NRC staff will perform, including the appropriate regional office staff. Finally, Appendix C contains guidance on the preparation and content of procedures for preoperational, fuel loading, initial criticality, low power, and power ascension tests.

III. Backfitting and Issue Finality

Issuance of this final regulatory guide does not constitute backfitting as defined in 10 CFR 50.109 (the Backfit Rule) and is not otherwise inconsistent with the issue finality provisions in 10 CFR Part 52. As discussed in the “Implementation” section of this regulatory guide, the NRC has no current intention to impose this regulatory guide on holders of current operating licenses or combined licenses.

This regulatory guide may be applied to applications for operating licenses and combined licenses docketed by the NRC as of the date of issuance of the final regulatory guide, as well as future applications for operating licenses and combined licenses submitted after the issuance of the regulatory guide. Such action does not constitute backfitting as defined in 10 CRF 50.109(a)(1) or is otherwise inconsistent with the applicable issue finality provision in 10 CFR Part 52, inasmuch as such applicants or potential applicants are not within the scope of entities protected by the Backfit Rule or the relevant issue finality provisions in Part 52.
