NUCLEAR REGULATORY COMMISSION

[NRC-2014-0085]


Information on Licensing Applications for Fracture Toughness 
Requirements for Ferritic Reactor Coolant Pressure Boundary Components

AGENCY: Nuclear Regulatory Commission.

ACTION: Draft regulatory issue summary; request for comment.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is seeking public 
comment on draft regulatory issue summary (RIS) 2014-XX. This draft RIS 
would provide guidance to applicants for, and holders of, nuclear power 
reactor licenses, construction permits, standard design approvals, and 
manufacturing licenses, and applicants for standard design 
certifications, on the scope and detail of information that should be 
provided in licensing applications regarding reactor vessel fracture 
toughness and associated pressure-temperature limits.

DATES: Submit comments by May 19, 2014. Comments received after this 
date will be considered if it is practical to do so, but the NRC is 
able to assure consideration only for comments received on or before 
this date.

ADDRESSES: You may submit comment by any of the following methods 
(unless this document describes a different method for submitting 
comments on a specific subject):
     Federal Rulemaking Web site: Go to http://www.regulations.gov and search for Docket ID NRC-2014-0085. Address 
questions about NRC dockets to Carol Gallagher; telephone: 301-287-
3422; email: [email protected]. For technical questions, contact 
the individual(s) listed in the FOR FURTHER INFORMATION CONTACT section 
of this document.
     Mail comments to: Cindy Bladey, Chief, Rules, 
Announcements, and Directives Branch (RADB), Office of Administration, 
Mail Stop: 3WFN, 06-44M, U.S. Nuclear Regulatory Commission, 
Washington, DC 20555-0001.
    For additional direction on accessing information and submitting 
comments, see ``Accessing Information and Submitting Comments'' in the 
SUPPLEMENTARY INFORMATION section of this document.

FOR FURTHER INFORMATION CONTACT: Alexandra Popova, Office of Nuclear 
Reactor Regulation (NRR), telephone: 301-415-2876, email: 
[email protected]; or Tanya Mensah, NRR, telephone: 301-415-

I. Accessing Information and Submitting Comments

A. Accessing Information

    Please refer to Docket ID NRC-2014-0085 when contacting the NRC 
about the availability of information regarding this document. You may 
access publicly-available information related to this action by the 
following methods:
     Federal Rulemaking Web site: Go to http://www.regulations.gov and search for Docket ID NRC-2014-0085.
     NRC's Agencywide Documents Access and Management System 
(ADAMS): You may access publicly-available documents online in the NRC 
Library at http://www.nrc.gov/reading-rm/adams.html. To begin the 
search, select ``ADAMS Public Documents'' and then select ``Begin Web-
based ADAMS Search.'' For problems with ADAMS, please contact the NRC's 
Public Document Room (PDR) reference staff at 1-800-397-4209, 301-415-
4737, or by email to [email protected]. The ADAMS accession number 
for each document referenced in this notice (if that document is 
available in ADAMS) is provided the first time that a document is 
referenced.
     NRC's PDR: You may examine and purchase copies of public 
documents at the NRC's PDR, Room O1-F21, One White Flint North, 11555 
Rockville Pike, Rockville, Maryland 20852.

B. Submitting Comments

    Please include Docket ID NRC-2014-0085 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 posts all comment submissions at http://www.regulations.gov as well as entering the comment submissions into 
ADAMS. The NRC does not routinely edit

[[Page 21813]]

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. Discussion

    The NRC issues RISs to communicate with stakeholders on a broad 
range of regulatory matters. This may include communicating staff 
technical positions on matters that have not been communicated to or 
are not broadly understood by the nuclear industry.
    The NRC staff has developed draft RIS 2014-XX, ``Information on 
Licensing Applications for Fracture Toughness Requirements for Ferritic 
Reactor Coolant Pressure Boundary Components'', to provide guidance on 
the scope and detail of information that should be provided in reactor 
vessel fracture toughness and associated P-T limits licensing 
applications to facilitate staff review. The RIS, if issued in final 
form, would be used by applicants for, and holders of, nuclear power 
reactor licenses, construction permits, standard design approvals, and 
manufacturing licenses, and applicants for standard design 
certifications. The draft RIS explains that these entities should 
ensure that P-T limits developed in accordance with the requirements of 
10 CFR Part 50, Appendix G sufficiently address all ferritic materials 
of pressure-retaining components of the reactor coolant pressure 
boundary, including the impact of structural discontinuities and 
neutron fluence accumulation. The draft RIS is available electronically 
under ADAMS Accession No. ML13301A188.

    Dated at Rockville, Maryland, this 10th day of April 2014.

    For the Nuclear Regulatory Commission.
Sheldon D. Stuchell,
Acting Chief Generic Communications Branch, Division of Policy and 
Rulemaking, Office of Nuclear Reactor Regulation.
