Content:
1.141 This memorandum documents the U.S. Nuclear Regulatory Commission (NRC) periodic review of Regulatory Guide (RG) 1.141, “Containment Isolation Provisions for Fluid Systems,” published in July 2010. This RG describes methods the NRC staff finds acceptable for complying with Title 10 of the Code of Federal Regulations Part 50, Appendix A, “General Design Criteria for Nuclear Power Plants.” As discussed in Management Directive 6.6, “Regulatory Guides,” the NRC staff reviews RGs approximately every 5 years to ensure that the RGs continue to provide useful guidance. The documentation of the Office of Nuclear Reactor Regulation (NRR) staff review is enclosed. Based on the results of the periodic review, the NRR staff concludes that no changes to RG 1.141 are warranted at this time. However, some non-technical issues were identified for future consideration. The NRR staff determined that any future revision of RG 1.141 should adopt the American National Standards Institute (ANSI)/American Nuclear Society (ANS) standard ANSI/ANS-56.2-1984, or a newer revision if available, with associated exceptions and clarifications.
