NUREG-0800 U.S. NUCLEAR REGULATORY COMMISSION STANDARD REVIEW PLAN BRANCH TECHNICAL POSITION 3-4 POSTULATED RUPTURE LOCATIONS IN FLUID SYSTEM PIPING INSIDE AND OUTSIDE CONTAINMENT REVIEW RESPONSIBILITIES Primary - Organization responsible for Mechanical Engineering reviews Secondary - None A. BACKGROUND This position on pipe rupture postulation is intended to comply with the requirements of Title 10 of Code of Federal Regulations (10 CFR) Part 50, “Domestic Licensing of Production and Utilization Facilities,” Appendix A, “General Design Criteria for Nuclear Power Plants,” General Design Criteria (GDC) 4, for the design of nuclear power plant structures, systems, and components (SSCs). It is recognized that pipe rupture is a rare event that may only occur under unanticipated conditions, such as those that might be caused by possible design, construction, or operation errors; unanticipated loads; or unanticipated corrosive environments. The staff’s observation of actual piping failures has indicated that they generally occur at high stress and fatigue locations, such as at the terminal ends of a piping system at its connection to the nozzles of a component. The criteria of this branch technical position (BTP) are intended to utilize the available piping design information by postulating pipe ruptures at locations having relatively higher potential for failure, such that an adequate and practical level of protection may BTP 3-4-2 Revision 3 –December 2016 be achieved.
