SURVEILLANCE RE0VIREMENTS 4.6.2.2 Each containment air recirculation and cooling unit shall be demonstrated OPERABLE:

a. .At least once per 31 days on a STAGGERED TEST BASIS by:

1. Starti y e r unit from the control room.

2. Verif;,ing that each unit operates for at least 15 minutes.

3. Verifying a cooling water flow rate of > 2000 gom to each cooling unit when the full flow service water outlet valves are fully open.

b. At least once per 18 months by verifying that each unit starts automatically on a--Gent &xnt Spny ttuathm test signal.
