er separation nor protective enclosures are practical and special protective measures are taken to ensure the operability of safety-related features. Review Interfaces5 1. SPLB, coordinates with other review branches as detailed below and reviews design features recommended in Section B.2 of BTP SPLB 3-1 as follows: a. The Mechanical Engineering Branch (EMEB) confirms the seismic and quality group classifications of systems and components defined as essential safety-related features in Appendix A of BTP SPLB 3-1, as part of its primary review responsibility for SRP Sections 3.2.1 and 3.2.2. b. SPLB identifies protective structures, piping restraints, and other measures used for protection against pipe breaks outside containment. Review of the specific aspects of these elements recommended in item B.2.b of BTP SPLB 3-1 is done by the Structural and Geosciences Branch (ESGB)Civil Engineering and Geosciences Branch (ECGB) and EMEB, as follows: 6 (1) ESGBECGB reviews the design of protective structures in connection 7 with the review of other Category I structures under SRP Section 3.8.4. (2) EMEB reviews the design of piping restraints and other protective measures in connection with the review of break locations and dynamic effects of piping failures under SRP Section 3.6.2. c. SPLB identifies portions of high and moderate energy fluid system piping between containment isolation valves that are subject to the recommendations of item B.2.c of BTP SPLB 3-1. EMEB reviews the design of these portions of piping in connection with the review of break locations and dynamic effects of piping failures under SRP Section 3.6.2. 3.6.1-3 DRAFT Rev. 3 - April 1996 2. SPLB reviews analyses of postulated piping failures with respect to the guidelines of Section B.3 of BTP SPLB 3-1. The locations and types of failures to be considered and the dynamic effects associated with the failures are reviewed by the EMEB under SRP Section 3.6.2. a. SPLB reviews analyses of piping failures in
