Nuclear Regulatory Commission December 23, 2009 – Federal Register Recent Federal Regulation Documents

The NRC is issuing the final License Renewal Interim Staff Guidance (LR-ISG), LR-ISG-2007-02, ``Changes to Generic Aging Lessons Learned (GALL) Report Aging Management Program (AMP) XI.E6, ``Electrical Cable Connections Not Subject to 10 CFR 50.49 Environmental Qualification Requirements.'' LR-ISG-2007-02 revises current NRC guidance in Section XI.E6 of NUREG-1801, Revision 1, ``Generic Aging Lessons Learned (GALL) Report,'' Volume 2, dated September 2005 (GALL Report). Volume 2 of the GALL Report is available in the NRC's Agencywide Documents Access and Management System (ADAMS) under Accession No. ML052780376. The revised GALL Report Section XI.E6 recommends an AMP with a one-time inspection for electrical cable connections not subject to 10 CFR 50.49 environmental qualification requirements, instead of the periodic inspection as currently recommended in the GALL Report. The NRC staff has determined that a one-time inspection, on a representative sample basis, is adequate to ensure that either aging of metallic cable connections is not occurring and/or that an existing preventive maintenance program is effective such that a periodic inspection is not required. The final LR-ISG-2007- 02 is available under Accession No. ML091940093.
