acceptable isolation features to maintain containment integrity as part of its primary review responsibility for SRP Section 6.2.4. For those areas of review identified above as being reviewed as part of the primary review responsibility of another branch, the acceptance criteria necessary for the review and their methods of application are contained in the referenced SRP section of the corresponding primary branch. 3.6.2-2 Rev. 1 - July 1981 II. ACCEPTANCE CRITERIA MEB acceptance criteria are based on meeting the requirements of General Design Criterion 4, as it relates to structures, systems, and components important to safety being designed to accommodate the dynamic effects of postulated pipe rupture, including postulation of pipe rupture locations; break and crack characteristics; dynamic analysis of pipe whip, and jet impingement loads. Specific criteria necessary to meet the relevant requirements of GOC 4 are as follows: 1. Postulated Pipe Rupture Locations Inside Containment Acceptable criteria to define postulated pipe rupture locations and con- figurations inside containment-are specified in Branch Technical Position (BTP) MEB 3-1 (Ref. 4). 2. Postulated Pipe Rupture Locations Outside Containment For protection against postulated pipe ruptures outside containment, BTP MEB 3-1 provide acceptable criteria to define postulated rupture locations and plant layout considerations. 3. Methods of Analysis Detailed acceptance criteria covering pipe whip dynamic analysis including determination of the forcing functions of jet thrust and jet impingement, are included in subsection II, "Review Procedures," of this SRP section. The general bases and assumptions of the analysis are given in BTP MEB 3-1, subsection B.3. III. REVIEW PROCEDURES The reviewer will select and emphasize material from this SRP section, as may be appropriate for a particular case. 1. The locations and configurations of breaks in high-energy piping and leakage cracks in moderate energy piping are
