In the review of other areas associated with the offsite power system, the PSBEELB will 14 coordinate other branches' evaluations that interface with the overall review of the system, as follows: 1. The Reactor Systems Branch (RSBSRXB ) determines those system components 15 16 requiring electric power as a function of time for each mode of reactor operation and accident condition as part of its primary review responsibility for SRP Sections 4.6, 5.4.6, 5.4.7, 5.4.12, and 6.3, and 9.3.5.17 2. The AuxiliaryPlant Systems Branch (ASBSPLB ) determines those system components 18 requiring electric power as a function of time for each mode of reactor operation and accident condition as part of its primary review responsibility for SRP Sections 6.5.1, 6.7, 9.1.3, 9.1.4, 9.29.2.1, 9.2.2, 9.2.4, 9.2.5, 9.2.6, 9.39.3.1, 9.3.3, 9.4.1 through 9.4.5, 9.5.1, 10.4.5, 10.4.7, and 10.4.9.19 3. The ASBSPLB also verifies, on request, the adequacy of those auxiliary systems 20 required for the proper operation of the preferred power system. These include such systems as heating and ventilation systems for switchgear in the circuits from the preferred power sources to the onsite power distribution system buses and main generator auxiliary systems such as the cooling water system, hydrogen cooling system, turbine electro-hydraulic control system , and air supply system. 21 4. The ASBSPLB verifies, on request, the physical arrangements of components and 22 structures of the preferred power system to assure ensure that the paths from the preferred power sources to the standby power distribution system buses will not experience simultaneous failure under operating or postulated accident environmental DRAFT Rev. 4 - April 1996 8.2-4 conditions. This includes the effects of floods, missiles, pipe whipping, and discharging fluids that result from equipment failures. 5. The SPLB examines fire detection and firefighting systems in preferred power system areas to ensure that the adverse effects of
