nt proposes to use leak-before-break technology to exclude the dynamic effects of postulated pipe ruptures from the design basis of plant structures, systems and components, the Materials and Chemical Engineering Branch (EMCB) will review the applicant’s design and analyses as part of its primary review responsibility for SRP Section 3.6.3 (later).9 DRAFT Rev. 3 - April 1996 3.6.1-4 3. The Materials Engineering Branch (EMTB)Civil Engineering and Geosciences Branch (ECGB) reviews inservice inspection aspects of piping within protective structures or 10 guard pipes, between containment isolation valves, as part of its primary review responsibility for SRP Section 6.6. For those areas of review identified above as part of the primary review responsibility of other branches, the acceptance criteria necessary for the review and their methods of application are contained in the referenced SRP section of the corresponding primary branch.11 II. ACCEPTANCE CRITERIA Acceptability of the plant design for protection against postulated piping breaks outside containment, as described in the applicant's safety analysis report (SAR), will be based on General Design CriterionGDC 4, as it relates to structures, systems and components important 12 to safety being designed to accommodate the dynamic effects of postulated pipe rupture, including the effects of pipe whipping and discharging fluids. Acceptance is based on conformance to Branch Technical Position SPLB 3-1, attached to this SRP section. Technical Rationale13 The technical rationale for application of these acceptance criteria is discussed in the following paragraphs: 14 Compliance with GDC 4 requires that structures, systems, and components important to safety shall be designed to accommodate the effects of, and be compatible with, environmental conditions associated with normal operations, maintenance, testing, and postulated accidents, including loss-of-coolant accidents. These structures, systems, and components shall
