SUPPLEMENTARY INFORMATION:
I. Background
On March 1, 2013 (78 FR 13911), the NRC published for public
comment the proposed revision to this section of the SRP. The staff
made changes to the proposed revision after consideration of comments
received. 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 SRP Section 3.7.1'' (ADAMS Accession No.
ML14198A462).
The changes to this SRP section reflect current staff's review
methods and practices based on lessons learned from NRC reviews of
design certification and combined license applications completed since
the last revision of this chapter. Changes include: (1) Enhancements to
guidance to the staff for evaluating the acceptability of seismic,
civil, structural design, and analysis issues, (2) updates to review
interfaces to improve the efficiency and consistency of staff reviews
and (3) updates to references covered in the section.
The revised section has incorporated staff dispositions of all
public comments received on the proposed revision. The most salient
changes in response to the public comments are the rewrite of Appendix
B to SRP Section 3.7.1. The new Appendix B provides further enhancement
of the guidance on developing power spectral density functions
associated with ground motion artificial time histories. No new SRP
acceptance criteria were added as a result of this rewrite of Appendix
B.
II. Backfitting and Issue Finality
Issuance of this final SRP section does not constitute backfitting
as defined in Sec. 50.109 of Title 10 of the Code of Federal
Regulations (10 CFR) (the Backfit Rule) and is not otherwise
inconsistent with the issue finality provisions in 10 CFR part 52. The
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. The NRC staff has no intention to impose the SRP positions on
current licensees and regulatory approvals either now or in the future.
The staff does not intend to impose or apply the positions
described in the SRP to existing (already issued) licenses and
regulatory approvals. Hence, the issuance of a final 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 SRP on holders
of already issued holders of licenses SRP 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.
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 which substantially changes the expectations of current and
future applicants.
[[Page 58]]
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 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 in a manner
which 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.
III. Congressional Review Act
In accordance with the Congressional Review Act, the NRC has
determined that this action is not a major rule and has verified this
determination with the Office of Information and Regulatory Affairs of
the Office of Management and Budget.
Dated at Rockville, Maryland, this 18th day of December, 2014.
For the Nuclear Regulatory Commission.

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