WITH THE POSTULATED RUPTURE OF PIPING REVIEW RESPONSIBILITIES Primary - Mechanical Engineering Branch (MEB) Secondary - None I. AREAS OF REVIEW General Design Criterion 4 (Ref. 1) requires that structures, systems, and compo- nents important to safety shall be designed to accommodate the effects of postu- lated accidents, including appropriate protection against the dynamic and environmental 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 MEB in accordance with this SRP section, to confirm that requirements for the protection of structures, systems, and components relied upon for safe reactor shutdown or to mitigate the consequences of a postulated pipe rupture are met. At the construction permit (CP) stage, the staff review covers the following specific areas: 1. The criteria used to define break and crack locations and configurations. 2. The analytical methods used to define the forcing functions, Including the Set thrust reaction at the postulated pipe break or crack location and jet Ipingement loadings on adjacent safety-related structures, systems, and components. 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.
