4.6* SAFETY INJECTION

~CONTAINMENT SPRAY SYSTEMS TES~

Surveillance Requirements 4.6.l Safety Injection System

a. System tests shall be performed at each reactor refueling interval.

A test safety injection signal will be applied to initiate operation of the system. The safety injection and shutdown cooling system pump motors may be de-energized for this test. The system will be considered satisfactory if control board indication and visual observations indicate that all components have received the safety injection signal in the proper sequence and timing (ie, the appropriate pump breakers shall have opened and closed, and all valves shall have completed their travel).

4.6.2 Containment Spray System

a. System test shall be performed at each reactor refueling interval.

The test shall be performed with the isolation valves in the spray supply lines at the containment blocked closed. Operation of the system is initiated by tripping the normal actuation instrumentation.

b. At least every ten years the spray nozzles shall be verified to be open.

c. The test will be considered satisfactory if visual observations indicate all components have operated satisfactorily.

4.6.3 Pumps

a. The safety injection pumps, shutdown cooling pumps, and containment spray pumps shall be started at intervals not to exceed three months. Alternate manual starting between control room console and the local breaker shall be practiced in the test program.

b. Acceptable levels of performance shall be that the pumps start, reach their rated heads on recirculation flow, and operate for at least fifteen minutes.

4.6.4 Valves

a. Each Safety Injection Tank flow path shall be verified OPERABLE within 7 days prior to each reactor startup by verifying each motor operated isolation valve is open by observing valve position indication and valve itself, and locking open the associated circuit breakers.

b. The Low Pressure Safety Injection flow path shall be verified OPERABLE within 7 days prior to each reactor startup by verifying flow control valve CV-3006 is open, and its air supply is isolated.
