NUCLEAR REGULATORY COMMISSION

[NRC-2013-0161]


Proposed Revision to Missiles Generated by Extreme Winds

AGENCY: Nuclear Regulatory Commission.

ACTION: Standard review plan-draft section revision; request for 
comment and use.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is soliciting 
public comment on a proposed revision 4 to Section 3.5.1.4, ``Missiles 
Generated by Extreme Winds,'' of NUREG-0800, ``Standard Review Plan for 
the Review of Safety Analysis Reports for Nuclear Power Plants: LWR 
Edition.'' This revision incorporates guidance and recommendations from 
Regulatory Guide (RG) 1.221, ``Design-Basis Hurricane and Hurricane 
Missiles for Nuclear Power Plants,'' and Interim Staff Guidance DC/COL-
ISG-024, ``Implementation of Regulatory Guide 1.221 on Design-Basis 
Hurricane and Hurricane Missiles.'' In addition, this revision provides 
clarification on areas of review and acceptance criteria for assessment 
of design-basis missiles generated by extreme winds. The revision also 
incorporates guidance on regulatory treatment of nonsafety systems.

DATES: Comments must be filed no later than September 9, 2013. Comments 
received after this date will be considered, if it is practical to do 
so, but the Commission is able to ensure consideration only for 
comments received on or before this date.

II. Further Information

    The Office of New Reactors and Office of Nuclear Reactor Regulation 
are revising Section 3.5.1.4 of the SRP from the current revision 3. 
Changes in this revision include new guidance for hurricane winds and 
associated missiles from RG 1.221, ``Design-Basis Hurricane and 
Hurricane Missiles for Nuclear Power Plants'' (ADAMS, Accession No. 
ML110940300), and Interim Staff Guidance DC/COL-ISG-024, 
``Implementation of Regulatory Guide 1.221 on Design-Basis Hurricane 
and Hurricane Missiles'' (ADAMS Accession No. ML13015A693).
    The NRC staff is issuing this notice to solicit public comments on 
the proposed revision 4 of Section 3.5.1.4 of the SRP. After the NRC 
staff considers any public comments, it will make a determination 
regarding the proposed revision to Section 3.5.1.4.

III. Backfitting and Issue Finality

    This draft SRP, if finalized, would provide guidance to the staff 
for reviewing applications for a construction permit and an operating 
license under Part 50 of Title 10 of the Code of Federal Regulations 
(10 CFR) with respect to missiles generated by extreme winds. The draft 
SRP would also provide guidance for reviewing an application for a 
standard design approval, a standard design certification, a combined 
license, and a manufacturing license under 10 CFR Part 52 with respect 
to those same subject matters.
    Issuance of this draft SRP, if finalized, would not constitute 
backfitting as defined in 10 CFR 50.109, or otherwise be inconsistent 
with the issue finality provisions in 10 CFR Part 52. The staff's 
position is based upon the following considerations.
    1. The draft SRP positions, if finalized, do not constitute 
backfitting, inasmuch as the SRP is internal guidance to NRC staff.
    The SRP provides interim 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 applicants 
or licensees are protected under 10 CFR 50.109 or issue finality 
provisions in 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 under 10 CFR Part 52--with 
certain exclusions discussed below--were intended to every NRC action 
which 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, at 
this time, intend to impose the positions represented in the draft SRP 
section (if finalized) 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 section (if finalized) in a manner which does 
not provide issue finality as described in the applicable issue 
finality provision, then the staff must make address the criteria for 
avoiding issue finality as described in the applicable issue finality 
provision.
    3. The staff has no intention to impose the draft 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 draft SRP section to existing (already issued) 
licenses (e.g., operating licenses and combined licenses) and 
regulatory approvals--in this case, design certifications. Hence, the 
draft SRP--even if considered guidance which 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 draft SRP (if finalized) on holders of already issued holders of 
licenses in a manner which 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 applicable issue finality 
provision, as applicable.

    Dated at Rockville, Maryland, this 1st day of August 2013.

    For the Nuclear Regulatory Commission.
George M. Tartal,
Acting Chief, Policy Branch, Division of Advanced Reactors and 
Rulemaking, Office of New Reactors.
