SUPPLEMENTARY INFORMATION: 

I. Background

    On June 11, 2013 (78 FR 35072), the NRC published for public 
comment the initial issuance of SRP Section 19.4, ``Strategies and 
Guidance to Address Loss of Large Areas of the Plant Due to Explosions 
and Fires.'' This section has been developed to assist NRC staff with 
the review of applications for certain construction permits, operating 
licenses, license amendments, certain standard design certifications, 
and combined licenses under parts 50 and 52 of Title 10 of the Code of 
Federal Regulations (10 CFR). It also informs new reactor applicants 
and other affected entities of SRP guidance regarding an acceptable 
method by which staff performs its review of the subject of loss of 
large areas of the plant due to explosions and fires.
    The NRC staff made several changes to the final revision of the 
subject guidance since issuance of the proposed revision. The staff 
clarified its expectations with Nuclear Energy Institute (NEI) 06-12, 
``B.5.b Phase 2 & 3 Submittal Guideline,'' in the SRP Acceptance 
Criteria subsection of the guidance. Additionally, some content 
previously seen in the proposed revision under Appendix A, ``Experience 
Gained from Implementation of Temporary Instruction 2515/171, 
Verification of Site Specific Implementation of B.5.b Phase 2 & 3 
Mitigating Strategies at Currently Licensed Power Reactor Sites and 
Related Staff Positions,'' was integrated into the Areas of Review and 
SRP Acceptance Criteria subsections. The remainder of the content from 
the proposed Appendix A was removed from the final guidance. Finally, 
the staff updated the SRP section's list of review interfaces to 
include additional interfacing SRP sections.
    The NRC staff received comment submissions on the proposed 
revision. Public comments are documented alongside the NRC staff's 
respective response in ADAMS under Accession No. ML13295A535. A redline 
strikeout comparing the proposed draft and final revisions can be found 
in ADAMS under Accession No. ML13316B153.
    Revision to this SRP section will supercede the staff guidance 
presented in Interim Staff Guidance DC/COL-ISG-016, ``Compliance with 
10 CFR 50.54(hh)(2) and 10 CFR 52.80(d), Loss of Large Areas of the 
Plant due to Explosions or Fires from a Beyond-Design Basis Event.'' As 
a result, the NRC staff will be retiring DC/COL-ISG-016 in a subsequent 
Federal Register notice.

II. Backfitting and Issue Finality

    Issuance of this final SRP section 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. The 
NRC staff's position is based upon the following considerations:
    1. The SRP positions do not constitute backfitting, inasmuch as the 
SRP is internal guidance directed at the NRC staff with respect to 
their regulatory responsibilities.
    The SRP provides guidance to the 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. Backfitting and issue finality--with certain exceptions 
discussed below--do not 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 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 staff does not 
currently intend to impose the positions represented in this SRP 
section in a manner that is inconsistent with any issue finality 
provisions of 10 CFR part 52. If in the future the NRC staff does 
indeed intend to impose positions inconsistent with these issue 
finality provisions, the NRC staff must address the regulatory criteria 
for avoiding issue finality.
    3. The NRC staff has no intention to impose the SRP positions on 
existing nuclear power plant licenses or regulatory approvals either 
now or in the future (absent a voluntary request for change from the 
licensee, holder of a regulatory approval, or a design certification 
applicant).
    The staff does not intend to impose or apply the positions 
described in the SRP section to existing (already issued) licenses 
(e.g., operating licenses and combined licenses) and regulatory 
approvals--in this case, design certifications. Hence, the issuance of 
this SRP guidance--even if considered guidance that is within the 
purview of the issue finality provisions in 10 CFR part 52--need not be 
evaluated as if it were a backfit or as being inconsistent with issue 
finality provisions. If, in the future, the 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

[[Page 39165]]

showing as set forth in the Backfit Rule, or address the criteria for 
avoiding issue finality as described applicable issue finality 
provision, as applicable.

III. Congressional Review Act

    This action is a rule as defined in the Congressional Review Act (5 
U.S.C. 801-808). However, the Office of Management and Budget has not 
found it to be a major rule as defined in the Congressional Review Act.

    Dated at Rockville, Maryland, this 25th day of June, 2015.

    For the Nuclear Regulatory Commission.
Lawrence Burkhart,
Acting Chief, New Reactor Rulemaking and Guidance Branch, Division of 
Advanced Reactors and Rulemaking, Office of New Reactors.
