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-ISGs in accordance with the LR-ISG Process, Revision 2 (ADAMS Accession No. ML100920158), for which a notice of availability was published in theFederal Registeron June 22, 2010 (75 FR 35510).

The NRC staff has developed draft LR-ISG-2012-02 to address: (a) Recurring internal corrosion, (b) a representative minimum sample size for periodic inspections in GALL Aging Management Program (AMP) XI.M38, “Inspection of Internal Surfaces in Miscellaneous Piping and Ducting Components,” (c) loss of coating integrity for Service Level III and Other coatings, (d) flow blockage of water-based fire protection system piping, (e) revisions to the scope and inspectionrecommendations of GALL AMP XI.M29, “Aboveground Metallic Tanks,” (f) corrosion under insulation, (g) external volumetric examination of internal piping surfaces of underground piping, (h) specific guidance for use of the pressurization option for inspecting elastomers in GALL AMP XI.M38, and (i) key miscellaneous changes to the GALL Report

III. Proposed Action

By this action, the NRC is requesting public comments on draft LR-ISG-2012-02. 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.
