Plants: LWR Edition,'' Appendix 18-A, ``Guidance for Crediting Manual
Operator Actions in Diversity and Defense-in-Depth Analyses.''
DATES: The effective date of this Standard Review Plan (SRP) update is
May 30, 2014.

SUPPLEMENTARY INFORMATION: On November 27, 2009 (74 FR 62355), the NRC
published for public comment the proposed appendix ``Guidance for
Crediting Manual Operator Actions in Diversity and Defense-in-Depth
(D3) Analyses'' in Chapter 18, ``Human Factors Engineering''. The staff
received a total of 12 comments on the draft appendix from one industry
stakeholder and the Advisory Committee for Reactor Safeguards. These
comments can generally be characterized as: (1) Requesting
clarification of the draft guidance, (2) requesting additional guidance
to address uncertainty in the analysis of time available and time
required for operator action, and (3) requesting that the guidance be
amended to allow for the crediting of actions in procedures other than
emergency operating procedures (EOPs) and in locations other than the
main control room. The staff made changes to the draft SRP in response
to the first two categories of comments but did not make changes in
response to the third category of comment. A summary of the comments
and the staff's disposition of the comments are available in a separate
document, Response to Public Comments on Draft Standard Review Plan
(SRP) Appendix 18-A, ``Guidance for Crediting Manual Operator Actions
in Diversity and Defense-in-Depth (D3) Analyses'' (ADAMS Accession No.
ML13115A144).
Backfitting and Issue Finality
Appendix 18-A of the SRP provides 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 human factors engineering. The SRP also
provides 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 these SRP section revisions does not constitute
backfitting as defined in 10 CFR 50.109 (the Backfit Rule) nor is it
inconsistent with the issue finality provisions in 10 CFR part 52. The
NRC's position is based upon the following considerations.
1. The SRP positions would not constitute backfitting, in as much
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 SRP to existing licenses and regulatory approvals.
Hence, the issuance of this SRP--even if considered guidance within the
purview
[[Page 24459]]
of the issue finality provisions in 10 CFR part 52--does 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) 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 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 SRP section 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.
Congressional Review Act:
This action is a rule as defined in the Congressional Review Act (5
U.S.C. Sec. Sec. 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 22nd day of April 2014.
For the Nuclear Regulatory Commission.

Chief, Policy Branch, Division of Advanced Reactors and Rulemaking,
Office of New Reactors.
