ADAMS. The NRC does not routinely edit comment submissions to remove 
identifying or contact information.
    If you are requesting or aggregating comments from other persons 
for submission to the NRC, then you should inform those persons not to 
include identifying or contact information that they do not want to be 
publicly disclosed in their comment submission. Your request should 
state that the NRC does not routinely edit comment submissions to 
remove such information before making the comment submissions available 
to the public or entering the comment submissions into ADAMS.

II. Further Information

    The NRC seeks public comment on the proposed draft revisions of 
Standard Review Plan (SRP) sections of Chapter 7 listed above. These 
sections have been developed to assist the NRC staff review the design 
of instrumentation and controls and auxiliary 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, updates to NRC guidance, and address the 
applicability of regulatory treatment of non-safety systems, where 
appropriate.

[[Page 55655]]

    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/. The SRP is 
guidance for the NRC staff. The SRP is not a substitute for the NRC 
regulations, and compliance with the SRP is not required.

III. Backfitting and Issue Finality

    Issuance of these draft SRP sections, if finalized, would not 
constitute backfitting as defined in 10 CFR 50.109 (the Backfit Rule) 
or otherwise be inconsistent with the issue finality provisions in 10 
CFR part 52. The NRC's position is based upon the following 
considerations:
    1. The draft SRP positions, if finalized, 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 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.
    3. Backfitting and issue finality do not--with limited exceptions 
not applicable here--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. 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) and/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 draft 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 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.
