NUCLEAR REGULATORY COMMISSION
[NRC-2015-0220]
Seismic Design Classification for Nuclear Power Plants
AGENCY: Nuclear Regulatory Commission.
ACTION: Regulatory guide; issuance.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing
Revision 5 of Regulatory Guide (RG) 1.29, ``Seismic Design
Classification for Nuclear Power Plants.'' This RG describes a method
that the staff of the NRC considers acceptable for use in identifying
and classifying those features of light-water-reactor (LWR) nuclear
power plants that must be designed to withstand the
[[Page 46118]]
effects of the safe-shutdown earthquake (SSE).

SUPPLEMENTARY INFORMATION:
I. Introduction
The NRC is issuing a revision to an existing guide in the NRC's
``Regulatory Guide'' series. This series was developed to describe and
make available to the public information regarding methods that are
acceptable to the NRC staff for implementing specific parts of the
agency's regulations, techniques that the staff uses in evaluating
specific issues or postulated events, and data that the staff needs in
its review of applications for permits and licenses.
Revision 5 of RG 1.29 was issued with a temporary identification of
Draft Regulatory Guide, DG-1315. Revision 5 of RG 1.29 contains minor
non-substantive changes that do not present new regulatory
requirements, but clarifies content in Section C, ``Staff Regulatory
Guidance,'' by (1) addition of a reference to the definition of the
reactor coolant pressure boundary in section 50.2 of title 10 of the
Code of Federal Regulations (10 CFR), and (2) a reorganization of
systems and subsystems to add clarity to the staff guidance. In
addition, it adds a reference to a related international standard, and
it was reformatted to align with the current program guidance for
regulatory guides.
II. Additional Information
The DG-1315 was published in the Federal Register (80 FR 55878) on
September 17, 2015 for a 60-day public comment period. Public comments
on DG-1315 and the staff's responses to the public comments are
available in ADAMS under Accession No. ML16118A149.
III. Backfitting and Issue Finality
The RG 1.29 describes a method that the staff of the NRC considers
acceptable for use in identifying and classifying those features of LWR
nuclear power plants that must be designed to withstand the effects of
the SSE. Issuance of this RG 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. As discussed in
the ``Implementation'' section of this RG, the NRC has no current
intention to impose this RG on holders of current operating licenses or
combined licenses.
This RG may be applied to applications for operating licenses,
combined licenses, early site permits, and certified design rules
docketed by the NRC as of the date of issuance of the final regulatory
guide, as well as future applications submitted after the issuance of
the regulatory guide. Such action would not constitute backfitting as
defined in the Backfit Rule or be otherwise inconsistent with the
applicable issue finality provision in 10 CFR part 52, inasmuch as such
applicants or potential applicants are not within the scope of entities
protected by the Backfit Rule or the relevant issue finality provisions
in part 52.
Dated at Rockville, Maryland, this 8th day of July 2016.
For the Nuclear Regulatory Commission.

Acting Chief, Regulatory Guidance and Generic Issues Branch, Division
of Engineering, Office of Nuclear Regulatory Research.
