at least 5000 gpa against a test line pressure of r _ % psig when steam is being supplied to the turbine at 150 1 15 psig.a

3. Performing a CHANNEL CALIBRATION of the CSS header SP instru-mentation and verifying the setpoint to be i 1 psid.

4. Verifying that the suction for the HPCI system is automatically transferred from the condensate storage tank to the suppression chamber on a condensate storage tank water level - low signal and on a suppression chamber - water level high signal.

5. Performing a CHANNEL CALIBRATION of the condensate transfer pump (ischarge low pressure alarm instrumentation and verifying the ow pressure alarm setpoint to be > 113 psig.

d. . . the ADS:

1. At least once per 31 days, performing a CHANNEL FUNCTIONAL TEST of the accumulator backup compressed gas system low pressure alarm system.

2. At least once per 18 months:

a) Performing a system functional test which includes simulated automatic actuation of the system throughout its emergency operating sequence, but excluding actual valve actuation, b) Manually"* opening each ADS valve when the reactor steam dome pressure is greater than or equal to 100 psig" and observing that either:

1) The control valve or bypass valve position responds accordingly, or

2) There is a corresponding change in the measured steam flow, c) Performing a CHANNEL CALIBRATION of the accumulator backup compressed gas system low pressure alarm systems and veri-fying air alarm setpoint of 2070 + 35 psig on decreasing pressure.

l

e. At least every 18 months the following shall be accomplished by any series of sequential, overlapping or total channel steps such that the entire channel is tested:

l L

• The provisions of Specification 4.0.4 are not applicable provided the surveillance is performed within 12. hours after reactor steam pressure is adequate to perform the test.

~

• • ADS solenoid energization shall be used alternating between ADS Division 1 and ADS Division 2.
