II. Further Information

    The NRC seeks public comment on the proposed draft section revision 
of SRP Section BTP 5-3. The changes include incorporation of text 
describing NRC review of potential non-conservatisms in BTP 5-3, 
Revision 2, Subsection B1.1; a reference to a memorandum describing the 
results of the NRC review of the potential non-conservatisms; and 
numerous textual updates to incorporate pressure-temperature limit 
reports, 10 CFR 50.61a, 10 CFR part 52, ``Licenses, Certifications, and 
Approvals for Nuclear Power Plants,'' clearer citations, and nozzle 
language.
    Following NRC staff evaluation of public comments, the NRC intends 
to finalize SRP Section BTP 5-3 in ADAMS and post it on the NRC's 
public website 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 this draft SRP section, 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 
directed at the NRC staff with respect to their regulatory 
responsibilities.
    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 
current licensees or already-issued regulatory approvals 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 (already issued) 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. 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 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 which does not provide issue finality as 
described in the applicable issue finality provisions, then the staff 
must address the criteria for avoiding issue finality as described in 
the applicable issue finality provision.

    Dated at Rockville, Maryland, this 10th day of July, 2018.

    For the Nuclear Regulatory Commission.
Jennivine K. Rankin,
Acting Chief, Licensing Branch 3, Division of Licensing, Siting, and 
Environmental Analysis, Office of New Reactors.
