4.7.7.2 The bottled air pressurization system.shall be demonstrated OPERABLE:

a. At least once per 31 days by verifying that the-system l contains a minimum of 10 bottles of air each l pressurized to at least 1825 psig and-by verifying that

'the system solenoid operated valves are powered from an operable emergency bus.

b. At least once per 18 months be verifying that: l

1. A chlorine / control room high radiation / containment phase B isolation ' test signal'from either Unit

• will initiate system operation.

2. Upon a partial discharge test using four out'of five bottled air subsystems the system will supply 1 1000 cfm of air and pressurize the control room to 11/8 inch Water Gauge relative to the.outside atmosphere during system operation.**
