Draft license renewal guidance; request for comment.


The NRC requests public comment on Draft License Renewal Interim Staff Guidance (LR-ISG), LR-ISG-2011-05, “Ongoing Review of Operating Experience.” This LR-ISG provides guidance and clarification concerning ongoing review of plant-specific and industry-wide operating experience as an attribute of aging management programs used at nuclear power plants for compliance with Title 10 of the Code of Federal Regulations (10 CFR) part 54, “Requirements for Renewal of Operating Licenses for Nuclear Power Plants.”


Comments must be filed no later than September 23, 2011. 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.

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-2011-05 to clarify guidance on how the ongoing review of operating experience should be used to ensure the effectiveness of the license renewal aging management programs. While the SRP-LR states that an acceptable aging management program should include the ongoing review of operating experience, the program descriptions in the GALL Report do not reflect this guidance. As such, the NRC staff is proposing revisions to the GALL Report aging management programs to better align them with the guidance in the SRP-LR. The NRC staff is also proposing to revise its review procedures and acceptance criteria for comparing aging management review results with the GALL Report to better address this issue. In addition, the NRC staff is proposing to clarify the SRP-LR's description of the operating experience program element. One reason for this clarification is to better describe how license renewal applicants should obligate themselves to the ongoing review of operating experience for license renewal.

The NRC staff's proposed guidance addresses the ongoing review of operating experience as a generic activity applicable to all license renewal aging management programs. The NRC staff believes that this approach is consistent with how nuclear power plant licensees currently implement operating experience review activities. In addition, the NRC staff is proposing that licensees may credit these existing operating experience review activities, provided they ensure that these existing activities are appropriate for reviewing operating experience specifically related to aging management.

Proposed Action

By this action, the NRC is requesting public comments on draft LR-ISG-2011-05. 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.
