  • z3 '.

1.1 '

The purpose of this test is to perform the following periodic inservice tests as required by

. ASME Boiler and Pressure Vessel Code,Section XI, Rules for Inservice Inspection of i

_.'. ~

- -.2, _ % Nuclear Power Plant Components.

-1.1.1-A quarterly full-stroke test of 2IA-3047 and 21A-3048, instrument air to containment isolation valves.

3 i

1.1.2 A quarterly check valve shut exercise test ofIA-1314 and IA-1324 instrument air to containment check valves.

i 1.2 Testing of 21A-3047 and 2IA-3048 also satisfies environmental qualification requirements.

f 2.0 PRECAUTIONS AND LIMITATIONS

}

2.1 Minimize the time that the instrument air isolation valves are ~ shut to avoid a low l

instrument air pressure condition in containment.

2.2 For the purpose of valve stroke testing, stroke time is the time it takes a valve to go from full open to full shut or full shut to full open, by the control board indication. The 4

j stopwatch should be started at the moment the control switch is actuated.

2.3 The procedure requires the use of a Level 2 Dedicated Operator in accordance with OM 3.26.

2.4 '

Instrument air header pressure should be monitored whenever sections of the air header j

are being vented.
