MEMORANDUM TO: Louise Lund, Director Division of Engineering Office of Nuclear Regulatory Research FROM: Michael X. Franovich, Director Division of Risk Assessment Office of Nuclear Reactor Regulation SUBJECT: RESULTS OF PERIODIC REVIEW OF REGULATORY GUIDE 1.143, REVISION 2 This memorandum documents the U.S. Nuclear Regulatory Commission (NRC) periodic review of Regulatory Guide (RG) 1.143, Revision 2, “Design Guidelines for Radioactive Waste Management Systems, Structures and Components installed in Light Water-Cooled Nuclear Power Plants.” A review of the guide is enclosed with this memorandum. The RG, which was last revised in 2001, describes methods that NRC staff considers acceptable for complying with the NRC’s regulations in the design, construction, installation, and testing of the structures, systems, and components of radioactive waste management facilities in light water-reactor nuclear power plants. As discussed in Management Directive 6. 6 “Regulatory Guides,” the NRC staff reviews RGs approximately every 10 years to ensure that the guides continue to provide useful guidance. Based on the results of the periodic review, the staff concludes that no changes to RG 1.143, Revision 2 are warranted at this time. However, the staff identified some technical or regulatory issues in the review that could warrant addressing in a future revision. A revision to the RG could benefit new reactor applications. With few light water reactor applicants expected in the coming years and significant staff resources necessary to revise the RG, the staff does not believe that a RG update is justified at this time. The staff will evaluate the need to revise the RG during the next periodic review.
