n, the ICSB will coordinate with branches that interface with the overall review of systems required for safe.shutdown including the following: The -Power Systems Branch (PSB) evaluates the redundancy of power sources, the criteria for physical separation of redundant electrical equipment,' cabling, and cable trays; criteria for providing control and motive power 7.4-27 . Rev. 2 - July 1981 to these systems and the provisions for sharing electrical systems between unit plants as part of its primary review responsibility for SRP Section 8.2, 8.3.1, and 8.3.2. The Chemical Engineering Branch (CMEB) evaluates the conformance to the fire protection requirements with respect to remote shutdown capability as part of its primary.review responsibility for SRP Section 9.5.1. The Auxiliary Systems Branch (ASB) evaluates the adequacy of those auxiliary systems required for the proper operation of the systems required for safe shutdown as part of its primary review responsibility for SRP Chapters 9 and 10. These systems include compressed air, cooling water, boration, lighting, communications, heating, air conditioning, etc. The ASB review confirms the physical arrangement of components and structures related to the systems required for safe shutdown and their supporting systems, and determine that single events will not disable redundant systems. The Containment Systems Branch (CSB) reviews the containment ventilation and atmosphere control systems provided to maintain required environmental conditions for electrical and instrumentation equipment associated with the systems for safe shutdown and located inside containment as part of its primary review responsibility for SRP Chapter 6.0. The Equipment Qualifications Branch (EQB) reviews the seismic and environmental qualification of instrumentation and electrical systems as part of its primary review responsibility'for SRP Sections 3.10 and 3.11.
