.l. RANCHO SECO UNIT 1 TECHNICAL SPECIFICATIONS Surveillance Standards 4.5.2 REACTOR BUILDING COOLING SYSTEMS Applicability Applies to testing of the Reactor Building cooling systems.

Objective To verify that the Reactor Building cooling systems are operable.

Specification 4.5.2.1 System Tests A. Reactor Building Spray System

.1 During each refueling interval a system test shall be conducted to demonstrate proper operation of the system.

A manual trip signal will be applied to demonstrate actuation of the Reactor Building spray system (except for Reactor Building motor-operated inlet valves which prevent water entering nozzles). Water will be circulated from the borated water storage tank through the Reactor Building spray pumps and returned through the test line to the borated water storage tank.

.2 Air will be introduced into the spray headers to verify the availability of the headers and spray nozzle at least every 10 years.

.3 The test will be considered satisfactory if visual observation and control board indication verifies that all components have responded to the actuation signal and the appropriate pump breakers shall have opened and closed, and all valves shall have completed their travel except the blocked Reactor Building inlet valve.

B. Reactor Building Euergency Cooling System

.1 During each refueling interval, a system test shall be conducted to demonstrate proper operation of the system.

121H The test shall be performed in accordance with the procedure summarized below:

a. A manual trip signal will be applied to actuate the Reactor Building emergency cooling system for Reactor Building cooling operation.
