Interim staff guidance; issuance.


The U.S. Nuclear Regulatory Commission (NRC) is issuing License Renewal Interim Staff Guidance (LR-ISG), LR-ISG-2011-02, “Aging Management Program for Steam Generators.” This LR-ISG provides the NRC staff's evaluation of the suitability of using Revision 3 of the Nuclear Energy Institute's (NEI) document, NEI 97-06, “Steam Generator Program Guidelines,” (NRC's Agencywide Documents Access and Management System (ADAMS) Accession No. ML111310712) to manage steam generator aging. The LR-ISG revises the NRC staff's aging management recommendations currently described in Chapter XI.M19 of NUREG-1801, “Generic Aging Lessons Learned (GALL) Report,” Revision 2, dated December 2010, which is available in ADAMS under Accession No. ML103490041; and NUREG-1800, Revision 2, “Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants,” which is available in ADAMS under Accession No. ML103490036.
