April 29, 2015 MEMORANDUM TO: Brian E. Thomas, Director Division of Engineering Office of Nuclear Regulatory Research FROM: Lawrence E. Kokajko, Director /RA/ Division of Policy and Rulemaking Office of Nuclear Reactor Regulation SUBJECT: RESULTS OF PERIODIC REVIEW OF REGULATORY GUIDE 1.133 - REVISED This memorandum supersedes the January 29, 2015, memorandum available in the Agencywide Documents Access and Management System at Accession No. ML15008A060, on the same subject and documents the updated U.S. Nuclear Regulatory Commission periodic review of Regulatory Guide (RG) 1.133, “Loose-Part Detection Program for Primary System of Light-Water-Cooled Reactors,” published in May 1981. The RG provides guidance on loose-part detection program for the primary system of light-water cooled reactors. As discussed in Management Directive 6.6, “Regulatory Guides,” the NRR staff reviews RGs approximately every five years to ensure that the RGs continue to provide useful guidance. The NRR staff revised the results of their review to address additional questions and comments from your staff. The documentation of the NRR staff review is enclosed. Based on the results of the periodic review, the NRR staff concludes that no immediate changes to RG 1.133, Revision 1, are warranted at this time. However, the NRR staff plans to complete a detailed evaluation of regulatory issues and references to assess their impact on RG 1.133. The NRR staff will publish a report on this evaluation, including a determination of the future need to revise RG 1.133, in approximately one year.
