ASSOCIATED WITH THE POSTULATED RUPTURE OF PIPING REVIEW RESPONSIBILITIES Primary- Organization responsible for Mechanical Engineering reviews Secondary- None I. AREAS OF REVIEW 10 CFR 50, Appendix A, General Design Criterion (GDC) 4 requires, in part, that structures, systems, and components (SSCs) important to safety be designed to accommodate the effects of postulated accidents, including appropriate protection against the dynamic effects of postulated pipe ruptures. Information concerning break and crack location criteria and methods of analysis for evaluating the dynamic effects associated with postulated breaks and cracks in high- and moderate-energy fluid system piping, including "field run" piping inside and outside of containment, should be provided in the applicant's safety analysis report (SAR). This information is reviewed by the staff in accordance with this Standard Review Plan (SRP) section to confirm that there is appropriate protection of SSCs components relied upon for safe reactor shutdown or to mitigate the consequences of a postulated pipe rupture. The specific areas of review are as follows: 3.6.2-2 Revision 2 - March 2007 1. The criteria used to define break and crack locations and configurations. 2. The analytical methods used to define the forcing functions, including the jet thrust reaction at the postulated pipe break or crack location and jet impingement loadings on adjacent safety-related SSCs. 3. The dynamic analysis methods used to verify the integrity and operability of mechanical components, component supports, and piping systems, including restraints and other protective devices, under postulated pipe rupture loads. 4. The criteria for defining pipe break and crack locations and configurations. 5. The criteria dealing with special features, such as augmented inservice inspection programs or the use of special protective devices such as pipe-whip restraints, including diagrams showing final configurations, locations, and orientations
