SURVEILLANCE REQIJIREMENTS 4.7.8.1 The Auxiliary Building ventilation exhaust system sha!! be demonstrated OPERABLE:

a.

At least once per 31 days on a STAGGERED TEST BASIS by initiating, from the control room, flow through the HEPA filters and charcoal adsorbers and verifying tnat the system operates for at least 15 minutes.

b.

At least once per 18 months or (1) after any structural maintenance on the HEPA filters or charcoal adsorber housings; or (2) following painting, fire or chemical release in any ventilation zone communicating with the system by:

1.

Verifying that with the system operating at a flow rate of 156,680 cfm

+ 10% and exhausting through the HEPA filters and charcoal adsorbers, the total bypass flow of the system to the facility vent, including leakage through the system diverting valves, is d 1% when the system is tested by admitting cold DOP at the system intake.
