Nuclear Regulatory Commission April 19, 2012 – Federal Register Recent Federal Regulation Documents

The U.S. Nuclear Regulatory Commission (NRC or the Commission) is supplementing a notice published in the Federal Register on March 20, 2012 (77 FR 16270), that requested public comments on draft license renewal interim staff guidance (LR-ISG), LR-ISG-2011-04, ``Updated Aging Management Criteria for PWR Reactor Vessel Internal Components.'' The original notice provided the ADAMS Accession Number for the main body of LR-ISG-2011-04 but did not include accession numbers for Appendices A and B of the LR-ISG. This supplement provides the appropriate ADAMS Accession Numbers for the LR-ISG in its entirety, and does not change any other information in the original notice for public comment.
