NUCLEAR REGULATORY COMMISSION
[NRC-2016-0201]
Nuclear Power Plant Instrumentation for Earthquakes
AGENCY: Nuclear Regulatory Commission.
ACTION: Draft regulatory guide; request for comment.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing for
public comment draft regulatory guide (DG)-1332, ``Nuclear Power Plant
Instrumentation for Earthquakes.'' This DG is proposed Revision 3 of
Regulatory Guide 1.12, ``Nuclear Power Plant Instrumentation for
Earthquakes.'' The NRC proposes to revise the guide to incorporate
advances in seismic instrumentation and operating experience since
Revision 2 of RG 1.12 was issued in 1997. The proposed revision
describes the seismic instrumentation criteria, including
instrumentation type, locations, characteristics, and maintenance, that
the NRC staff considers acceptable for nuclear power plants.
DATES: Submit comments by November 21, 2016. Comments received after
this date will be considered if it is practical to do so, but the NRC
is able to ensure consideration only for comments received on or before
this date. Although a time limit is given, comments and suggestions in
connection with items for inclusion in guides currently being developed
or improvements in all published guides are encouraged at any time.
ADDRESSES: You may submit comments by any of the following methods:
Federal Rulemaking Web site: Go to http://www.regulations.gov and search for Docket ID NRC-2016-0201. Address
questions about NRC dockets to Carol Gallagher; telephone: 301-415-
3463; email: [email protected]. For technical questions, contact
the individuals listed in the FOR FURTHER INFORMATION CONTACT section
of this document.
Mail comments to: Cindy Bladey, Office of Administration,
Mail Stop: OWFN-12H08, U.S. Nuclear Regulatory Commission, Washington,

obtain publically-available information related to this action by any
of the following methods:
Federal Rulemaking Web site: Go to http://www.regulations.gov and search for Docket ID NRC-2016-0201.
NRC's Agencywide Documents Access and Management System
(ADAMS): You may obtain publicly-available documents online in the
ADAMS Public Documents collection at http://www.nrc.gov/reading-rm/adams.html. To begin the search, select ``ADAMS Public Documents'' and

B. Submitting Comments
Please include Docket ID NRC-2016-0201 in your comment submission.
The NRC cautions you not to include identifying or contact
information that you do not want to be publicly disclosed in your
comment submission. The NRC posts all comment submissions at http://www.regulations.gov as well as enters the comment submissions into
ADAMS. The NRC does not routinely edit comment submissions to remove
identifying or contact information.
If you are requesting or aggregating comments from other persons
for submission to the NRC, then you should inform those persons not to
include identifying or contact information that they do not want to be
publicly disclosed in their comment submission. Your request should
state that the NRC does not routinely edit comment submissions to
remove such information before making the comment submissions available
to the public or entering the comment submissions into ADAMS.
II. Additional Information
The NRC is issuing for public comment a DG in the NRC's
``Regulatory Guide'' series. This series was developed to describe and
make
[[Page 64955]]
available to the public information regarding methods that are
acceptable to the NRC staff for implementing specific parts of the
NRC'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.
The DG entitled, ``Nuclear Power Plant Instrumentation for
Earthquakes,'' is proposed Revision 3 of RG 1.12, ``Nuclear Power Plant
Instrumentation for Earthquakes.'' The DG is temporarily identified by
its task number, DG-1332. The guide proposes revised guidance for the
seismic instrumentation criteria, including instrumentation type,
locations, characteristics, and maintenance, that the NRC staff
considers acceptable for nuclear power plants. The current revision of
RG 1.12 dates to 1997 and significant technological advances in seismic
instrumentation have since been made. Lessons learned from the recent
earthquakes that impacted the North Anna and Fukushima-Dai-ichi nuclear
power plants indicate a need to update seismic instrumentation guidance
relative to instrument characteristics, locations, installation, and
maintenance. In addition, the guide needs to be reformatted to align
with the current program guidance for regulatory guides.
III. Backfitting and Issue Finality
This DG describes the seismic instrumentation criteria, including
instrumentation type, locations, characteristics, and maintenance, that
the NRC staff considers acceptable for nuclear power plants. Issuance
of this DG, if finalized, would not constitute backfitting as defined
in Sec. 50.109 of title 10 of the Code of Federal Regulations (10 CFR)
(the Backfit Rule) and would not otherwise be inconsistent with the
issue finality provisions in 10 CFR part 52. As discussed in the
``Implementation'' section of this DG, the NRC has no current intention
to impose this guide, if finalized, on holders of current operating
licenses or combined licenses.
This DG 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 guide, as
well as future applications submitted after the issuance of the 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 10 CFR part
52.
Dated at Rockville, Maryland, this 16th day of September, 2016.
