II. Further Information The NRC seeks public comment on the proposed draft revisions of Standard Review Plan
(SRP)Sections 3.2.1, 3.2.2, 3.6.2, 3.9.1, 3.10, 5.2.1.1, 5.2.1.2, and BTP 3-4. These sections have been developed to assist NRC staff's review the design of structures, components, equipment, and systems, as well as assess compliance with codes, standards, and code cases for the reactor coolant system and connected systems under parts 50 and 52 of Title 10 of the *Code of Federal Regulation* s (10 CFR). The revisions to these SRP sections reflect no changes in staff position; rather they clarify the original intent of these SRP sections using plain language throughout in accordance with the NRC's Plain Writing Action Plan. Additionally, these revisions reflect operating experience, lessons learned, and updated guidance since the last revision, and address the applicability of regulatory treatment of non-safety systems where appropriate. Following NRC staff's evaluation of submitted comments, the NRC intends to finalize the proposed revisions of SRP Sections 3.2.1, 3.2.2, 3.6.2, 3.9.1, 3.10, 5.2.1.1, 5.2.1.2, and BTP 3-4 in ADAMS and post them on the NRC's public Web site at *http://www.nrc.gov/reading-rm/doc-collections/nuregs/staff/sr0800/.* III. Availability of Documents The ADAMS accession numbers for the current revisions, proposed draft revisions, and redline strikeouts comparing current revisions and the proposed revisions of individual sections are available in ADAMS under the following accession numbers: SRP Section Current revision ADAMS accession No. Proposed revision ADAMS accession No. Redline ADAMS accession No. Section 3.2.1, “Seismic Classification” Revision 2 (ML063190002) Revision 3 (ML14227A643) ML14198A162 Section 3.2.2, “System Quality Group Classification” Revision 2 (ML063190003) Revision 3 (ML14227A641) ML14198A145 Section 3.6.2, “Determination of Rupture Locations and Dynamic Effects Associated with the Postulated Rupture of Piping” Revision 2 (ML070660494) Revision 3 (ML14230A035) ML14198A166 Section 3.9.1, “Special Topics for Mechanical Components” Revision 3 (ML070430402) Revision 4 (ML14227A637) ML14198A150 Section 3.10, “Seismic and Dynamic Qualification of Mechanical and Electrical Equipment” Revision 3 (ML070720037) Revision 4 (ML14227A631) ML14198A171 Section 5.2.1.1, “Compliance with the Codes and Standards Rule, 10 CFR 50.55a” Revision 3 (ML070040003) Revision 4 (ML14227A623) ML14198A155 Section 5.2.1.2 , “Applicable Code Cases” Revision 3 (ML070040004) Revision 4 (ML14227A659) ML14198A172 Branch Technical Position 3-4, “Applicable Code Cases” Revision 2 (ML070800008) Revision 3 (ML14227A646) ML14198A126 IV. Backfitting and Issue Finality Issuance of these draft SRP sections does not constitute backfitting as defined in 10 CFR 50.109, nor is it inconsistent with any of the issue finality provisions in 10 CFR part 52. These draft SRP sections do not contain any new requirements for COL applicants or holders under 10 CFR part 52, or for licensees of existing operating units licensed under 10 CFR part 50. Rather, it contains additional draft guidance and clarification on staff review of Preliminary Amendment Requests. The NRC staff does not intend to impose or apply the positions described in the draft SRP to existing licenses and regulatory approvals. Hence, the issuance of a final SRP—even if considered guidance within the purview of the issue finality provisions in 10 CFR part 52—would 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. The NRC staff does not, at this time, intend to impose the positions represented in the draft SRP sections 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 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. Dated at Rockville, Maryland, this 14th day of August, 2015. For the Nuclear Regulatory Commission. Joseph Colaccino, Chief, New Reactor Rulemaking and Guidance Branch, Division of Advanced Reactors and Rulemaking, Office of New Reactors. [FR Doc. 2015-21074 Filed 8-24-15; 8:45 am]
