NUCLEAR REGULATORY COMMISSION

[NRC-2012-0070]


Updated Aging Management Criteria for Reactor Vessel Internal 
Components of Pressurized Water Reactors

AGENCY: Nuclear Regulatory Commission.

ACTION: Draft interim staff guidance; request for comment.

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

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC or the Commission) 
requests public comment on draft license renewal interim staff guidance 
(LR-ISG), LR-ISG-2011-04, ``Updated Aging Management Criteria for PWR 
Reactor Vessel Internal Components.'' This draft LR-ISG revises the 
guidance in the Standard Review Plan for Review of License Renewal 
Applications for Nuclear Power Plants (SRP-LR) and Generic Aging 
Lessons Learned (GALL) Report for the aging management of stainless 
steel structures and components exposed to treated borated water.

DATES: Submit comments by May 21, 2012. Comments received after this 
date will be considered, if it is practical to do so, but the NRC staff 
is able to ensure consideration only for comments received on or before 
this date.

public or entering the comment submissions into ADAMS.

Background

    The NRC issues LR-ISGs to communicate insights and lessons learned 
and to address emergent issues not covered in license renewal guidance 
documents, such as the GALL Report and SRP-LR. In this way, the NRC 
staff and stakeholders may use the guidance in an LR-ISG document 
before it is incorporated into a formal license renewal guidance 
document revision. The NRC staff issues LR-ISG in accordance with the 
LR-ISG Process, Revision 2 (ADAMS Accession No. ML100920158); for which 
a notice of availability was published in the Federal Register on June 
22, 2010 (75 FR 35510).
    The NRC staff has determined that existing guidance in the SRP-LR 
and GALL Report needs to be revised for PWR reactor vessel internal 
components. The guidance document changes that are proposed in draft 
LR-ISG-2011-04 are based on the conclusions of the NRC's revised safety 
evaluation (ADAMS Accession No. ML11308A770).

Proposed Action

    By this action, the NRC is requesting public comments on draft LR-
ISG-2011-04. This LR-ISG proposes certain revisions to NRC guidance in 
the SRP-LR and GALL Report. The NRC staff will make a final 
determination regarding issuance of the LR-ISG after it considers any 
public comments received in response to this request.

    Dated at Rockville, Maryland, this 13th day of March, 2012.

    For the Nuclear Regulatory Commission.
Melanie A. Galloway,
Acting Director, Division of License Renewal, Office of Nuclear Reactor 
Regulation.
