starting air system, and lubrication system are in accordance with the acceptance criteria. The ASBSPLB reviews the other aspects of the vital supportingauxiliary 125 supporting systems to verify that the design, capacities, and physical 126 independence of these systems are adequate for their intended functions. Included is a review of the heating, and ventilation, and air conditioning (H&VHVAC)127 systems identified as necessary to Class 1E systems, such as the H&VHVAC128 systems for the electrical switchgear and diesel generator rooms. The ASBSPLB129 will verify the adequacy of the H&VHVAC system design to maintain the 130 temperature and relative humidity in the room required for proper operation of the safety equipment during both normal and accident conditions. It will also verify that redundant H&VHVAC systems are located in the same enclosure as the 131 redundant unit they serve or are separated in accordance with the same criteria as those for the systems they support. 7. System Testing and Surveillance In ensuring that the proposed periodic onsite testing capabilities of the ac onsite power system satisfies the requirements of General Design CriterionGDC 18 and the positions of Regulatory Guides 1.108 1.9 and 1.118, the descriptive information 132 133 (CP and OL stages), functional logic diagrams (CP and OL stages), and electrical schematics (OL stage) are reviewed to verify that the design has the built-in 134 capability to permit integral testing of Class 1E systems on a periodic basis when the reactor is in operation . Basic criteria relevant to the review of the surveillance 135 and testability of safety-related aspects of the ac power system is also described in IEEE Std 603 as endorsed by Regulatory Guide 1.153.136 The descriptive information (CP and OL stages) and the design implementation as depicted on electrical drawings (OL stage) of the means proposed for 137 automatically indicating at the system level a bypassed or deliberately inoperative
