NUCLEAR REGULATORY COMMISSION
[NRC-2015-0153]
Acceptance of Commercial-Grade Design and Analysis Computer
Programs for Nuclear Power Plants
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), DG-1305, ``Acceptance of
Commercial-Grade Design and Analysis Computer Programs for Nuclear
Power Plants.'' This DG provides new (i.e., not preceded by earlier
guidance on the same subject) guidance that describes acceptance
methods that the staff of the NRC considers acceptable in meeting
regulatory requirements for acceptance and dedication of commercial-
grade design and analysis computer programs for nuclear power plants.
DATES: Submit comments by August 31, 2015. 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
(unless this document describes a different method for submitting
comments on a specified subject):

B. Submitting Comments
Please include Docket ID NRC-2015-0153 in the subject line of your
comment submission, in order to ensure that the NRC is able to make
your comment submission available to the public in this docket.
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 will post 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 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, ``Acceptance of Commercial-Grade Design and
Analysis Computer Programs for Nuclear Power Plants,'' is temporarily
identified by its task number, DG-1305. This DG provides new guidance
that describes acceptance methods that the staff of the NRC considers
acceptable in meeting regulatory requirements for acceptance and
dedication of commercial-grade design and analysis computer programs
for nuclear power plants.
II. Backfitting and Issue Finality
Draft Guide-1305 describes acceptable methods for meeting the
dedication requirements in part 21 of title 10 of the Code of Federal
Regulations (10 CFR) and 10 CFR 50.55(e) with respect to design and
analysis computer programs for nuclear power plants. The draft
regulatory guide, if finalized, would 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,
``Licenses, Certifications and Approvals for Nuclear Power Plants.''
This regulatory guide, if finalized, represents the first NRC guidance
on this subject. Issuance of new guidance, by itself, does not
represent backfitting unless the NRC intends to impose the guidance on
existing licensees and currently-approved design certification rules
issued under part 52. The NRC does not have such an intention. Existing
licensees and applicants of final design certification rules will not
be required to comply with the positions set forth in this draft
regulatory guide, unless the licensee or design certification rule
applicant seeks a voluntary change to its licensing basis with respect
to safety-related power operated valve actuators, and where the NRC
determines that the safety review must include consideration of the
qualification of the valve actuators. Further information on the
staff's use of the draft regulatory guide, if finalized, is contained
in the draft regulatory guide under Section D. Implementation.
Applicants and potential applicants are not, with certain
exceptions, afforded protection by either the Backfit Rule or any issue
finality provisions under part 52. Neither the Backfit Rule nor the
issue finality provisions under 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. Therefore, the positions in any final draft regulatory
guide, if imposed on applicants, would not represent backfitting
(except as discussed below). The exceptions to the general principle
are applicable whenever a combined license applicant references a part
52 license (i.e., an early site permit or a manufacturing license) and/
or part 52 regulatory approval (i.e., a design certification rule or
design approval. The staff does not, at this time, intend to impose the
positions represented in the draft regulatory guide in a manner that is
inconsistent with any issue finality provisions in these part 52
licenses and regulatory approvals. If, in the future, the staff seeks
to impose a position in this regulatory guide 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 applicable issue finality
provision.
