4.5.2 EMERGENCY CORE COOLING SYSTEM e '

s _ Applicability Applies to. periodic , testing requirement for emergency core cooling systems.

Minimum acceptable injection flow must be greater than or equal to 500 gpm per HPI pump when pump discharge pressure lis 600 psig'or greater (the' pressure

.b. Reactor Building Cooling and Isolation System

1. During each refueling. period,~a system test shall be conducted to demonstrate proper operation of the system.* A test signal l will actuate the R.B. emergency cooling system valves to demonstrate operability of the co31ers.

2. The test will be considered satisfactory if the valves have completed the'.r expected travel as evidenced by the control board component operating lights, and either the station-couputer or local verification.

The system test shall be conducted prior to heatup following Cycle 4 refueling.

l 4.5.3.2 cor.ponent Tests

a. At intarvals not to exceed three months, the components required for reactc r building cooling and isolation will be tested.

b. The test will be considered satisfactory if the valves have completed their expected travel as evidenced by the control board ccmponent operating lights, and either the station computer or local vetification.

Bases The reactor building cooling and isolation systens ant reactor building spray _

system'are designed to remove the heat in the. containment acrosphere to prevent the building pressure from excaeding the design pressure.

The delivery capability of one reactor building spray pump at a time can be tested by opening the valve in the line from the borated water storage tank, cpening the corresponding valve in the test line, and starting the corresponding pump. _

With the pumps shut down and the borated water storage tank outlet closed, the reactor building spray injection valves can each be opened and closed by the operator action. With the reactor building spray inlet valves closed, low pressure air can be blown through the test connections of the reactor building spray nozzles to demonstrate that the flow paths are open.

The equipment, piping, valves and instrumentation of the reactor building cooling system are arranged so that they can be visually inspected. The cooling units and associated piping are located outside the secondary concrete shield. Personnel can enter the reacter building during power operations to inspect and maintain this equipment.

The reactor building fans are nortally operating periodically, constituting the test that these fans are operable.
