4.6 SAFETY INJECTION AND CONTAINMENT SPRAY SYSTEMS TESTS (Contd)
I 4.6.5 Containment Air Cooling System
- a.
Emergency mode automatic valve and fan operation will be checked for operability during each refueling shutdown.
- b.
Each fan and valve required to function during accident conditions will be exercised at three-month intervals.
Basis The safety injection system and the containment spray system are principal Plant safety features that are normally inoperative during reactor operation.
Complete systems tests cannot be performed when the reactor is operat-ing because a safety injection signal causes containment isolation and a containment spray system test requires the system to be temporarily disabled.
The method of assuring operability* of these systems. is, therefore, to combine systems tests to be performed during annual Plant shutdowns, with more frequent component tests, which can be performed during reactor operation.
The annual systems tests demonstrate proper automatic operation of the safety injection and containment spray systems.
A test signal is applied to initiate automatic action and verification made that the components receive the safety injection in the proper sequence.
The test demonstrates the operation of the valves, pump circuit breakers, d
(1, 2) an automatic circuitry.
