OL) stage, the staff review covers the following specific areas: 1A. The implementation of criteria for defining pipe break and crack locations and 6 configurations. 2B. The implementation of 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 in relation to break locations in each piping system. 3C. The acceptability of the analysis results, including the jet thrust and impingement forcing functions and pipe-whip dynamic effects. 4D. The design adequacy of systems, components, and component supports to assureensure7 that the intended design functions will not be impaired to an unacceptable level of integrity or operability as a result of pipe-whip or jet impingement loadings. Review Interfaces8 In addition, the MEBThe EMEB will coordinate other branches' evaluations that interface with 9 the overall review of the plant protection against postulated pipe rupture, as follows: (1) The Auxiliary Systems Branch (ASB)Plant Systems Branch (SPLB) reviews plant 10 11 arrangements where separation of high- and moderate-energy systems is the method of protection for essential systems and components outside containment in SRP Section 3.6.1. The ASBSPLB identifies high- and moderate-energy systems outside 12 containment and the essential systems and components that must be protected from postulated pipe rupture in these high- and moderate-energy systems. (2) If an applicant 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).13 (3) The Structural Engineering Branch (SEB)Civil Engineering and Geosciences
