4. Reactor Buildino to Suporession chamber Vacuum Dreakers

a. The reactor building to suppression chamber vacuum breakers and associated instrumentation, including setpoint, shall be checked for proper operation overy three months.

b. During each refueling outage each vacuum breaker shall be tested l

to determine that the force required to open the vacuum breaker from closed to fully open does not exceed the force specified in Specification 3.5.A.4.a.

The air-operated vacuum breaker instrumentation shall be calibrated during each refueling outage.

5. Pressure SuDDression Chamher - Drvwell Vacuum Breakers

a. Ecriodie Onerability Tests i

once each month and following any release of energy which would tend to increase pressure to the suppression chamber, each operable suppression chamber - drywell vacuum breaker shall be exercised. Operation of position switches, indicators and alarms shall be verified monthly by operation of each operable vacuum breaker.

b. Refuelino Outace Teste (1)

All suppression chamber - drywell vacuum breakers shall be tested to determine the force required to open each valve from fully closed to fully open.

(2)

The suppression chamber - drywell vacuum breaker position indication and alarms systems shall be calibrated and functionally tested.

(3)

At least four of the suppression chamber - drywell vacuum breakers shall be inspected.

If deficiencies are found, all vacuum breakers shall be inspected and deficiencies corrected such that Specifications 3.5.A.5.a can be met.

(4)

A drywell to suppression chamber leak rate test (interval not to exceed 20 months) shall' demonstrate that with an initial differential pressure of not less than 1.0 poi, the differential pressure decay rate shall not exceed the equivalent of air flow through a 2-inch orifice.

K. Reactor Buildi_ng

1. Secondary containment capability tests shall be conducted after I

isolating the reactor building and placing either Standby Gas Treatment System filter train in operation.

2. The tests shall be performed at least once per operating cycle (interval not to exceed 20 months) and shall demonstrate the l

capability to maintain a h inch of water vacuum under calm wind conditions with a' Standby Gas Treatment System Filter train flow rate of not more than 4000 cfm.
