ACTION:

Draft interim staff guidance; request for public comment.

SUMMARY:

The U.S. Nuclear Regulatory Commission (NRC) requests public comment on Draft License Renewal Interim Staff Guidance (LR-ISG), LR-ISG-2011-03, “Changes to GALL Report Revision 2 Aging Management Program (AMP) XI.M41, `Buried and Underground Piping and Tanks'.” This LR-ISG provides changes to the recommendations in GALL Report Revision 2 AMP XI.M41 based on the staff's review of several license renewal applications' buried and underground piping and tanks aging management programs and stakeholder input. The draft LR-ISG proposes to revise an NRC staff-recommended aging management program in NUREG-1801, Revision 2, “Generic Aging Lessons Learned (GALL) Report,” and the NRC staff's aging management review procedure and acceptance criteria contained in NUREG-1800, Revision 2, “Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants” (SRP-LR).

DATES:

Submit comments by April 9, 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.

II. 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 developed draft LR-ISG-2011-03 to (a) include inspection recommendations for plants that will not have a cathodic protection system in the period of extended operation, (b) remove the recommendation to volumetrically inspect underground piping to detect internal corrosion, (c) base further increased inspection sample sizes on an analysis of extent of cause and extent of condition when adverse conditions are detected in the initial and subsequent doubled sample size rather than continuing to double the sample size, (d) add a recommendation that where damage to the coating is significant and the damage was caused by non-conforming backfill, an extent of condition evaluation should be conducted to ensure that the as-left condition of backfill in the vicinity of observed damage will not lead to further degradation, (e) add specific acceptance criteria for cathodic protection surveys, (f) add the specific preventive and mitigative actions utilized by the AMP in the FSAR Supplement description of the program as contained in the SRP-LR, and (g) make miscellaneous and editorial changes.

Proposed Action

By this action, the NRC is requesting public comments on draft LR-ISG-2011-03. This LR-ISG proposes certain revisions to NRC guidance on implementation of the requirements in 10 CFR Part 54. 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 1st day of March 2012.

For the Nuclear Regulatory Commission.

Melanie A. Galloway,

Acting Director, Division of License Renewal, Office of Nuclear Reactor Regulation.
