II. Further Information

    The NRC seeks public comment on the proposed draft revisions of 
Standard Review Plan (SRP) Sections 3.9.2, 3.9.4, 3.9.5, and 3.9.6. 
These sections have been developed to assist the NRC staff review the 
design of structures, components, equipment, and systems under parts 50 
and 52 of Title 10 of the Code of Federal Regulations (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 the NRC staff's evaluation of public comments, the NRC 
intends to finalize the proposed revisions of the subject SRP Sections 
in ADAMS and post them on the NRC's public Web site at http://www.nrc.gov/reading-rm/doc-collections/nuregs/staff/sr0800/.

IV. Backfitting and Issue Finality

    Issuance of these draft SRP sections, if finalized, 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contains additional draft guidance and clarification on staff review of 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 18th day of September, 2015.
