nding primary branch.19 II. ACCEPTANCE CRITERIA EMEB acceptance criteria are based on meeting the requirements of General Design 20 CriterionGDC 4, as it relates to structures, systems, and components important to safety being 21 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 GDC 4 are as follows: 1. Postulated Pipe Rupture Locations Inside Containment Acceptable criteria to define postulated pipe rupture locations and configurations inside containment are specified in Branch Technical Position (BTP) EMEB 3-1 (Ref. 4).22 2. Postulated Pipe Rupture Locations Outside Containment For protection against postulated pipe ruptures outside containment, BTP EMEB 3-1 23 provides acceptable criteria to define postulated rupture locations and plant layout 24 considerations. 3. Methods of Analysis DRAFT Rev. 2 - April 1996 3.6.2-4 Detailed acceptance criteria covering pipe-whip dynamic analysis, including determination of the forcing functions of jet thrust and jet impingement, are included in subsection III, "Review Procedures," of this SRP section. The general bases and assumptions of the analysis are given in BTP EMEB 3-1, subsection B.3. 25 Technical Rationale26 The technical rationale for application of these acceptance criteria to reviewing the determination of rupture locations and dynamic effects associated with the postulated rupture of piping is discussed in the following paragraphs:27 Compliance with GDC 4 requires that nuclear power plant structures, systems, and components important to safety be designed to accommodate the effects of, and be compatible with, environmental conditions associated with normal operation, maintenance, testing, and postulated accidents, including loss-of-coolant accidents. These structures, systems, and components
