2. For'het HPCI system, verifying that:

a) The system develops a flow of' at least 5600 gpm against a e test line pressure corresponding to a reactor vessel pressure d n 2 200 psig plus head and line losses, when steam is being ite er oo PvRv&,Pliee 1 18 1 r84 e at zoo 1s. - o .s4 . -

%pg"'g b) T ie suction is automatically transferred from the condensate 19 s ;orage tank to the suppression chamber on a condensate

..orage tank water level - low signal and on a suppression  !

chamber water level - high signal.

3. Perfoming a CHANNEL CALIBRATION of the CSS, LPCI, and HPCI system discharge line " keep filled" alam instrumentation.

4. Perfoming a CHANNEL CALIBRATION of the CSS header AP instru-mentation and verifying the setpoint to be s the allowable value of 4.4 psid.

5. Performing a CHANNEL CALIBRATION of the LPCI header AP instru-mentation and verifying the setpoint to be s the allowable va'lue of 3.0 psid.

d. For the ADS:

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

2. At least once per 24 months:

a) Perfoming a system functional test which includes simulated automatic actuation of the system throughout its emergency operating sequence, but excluding actual valve actuation.

b) ly opening each ADS valve when the reactor steam dome pre is greater than or equal to 100 psi and observing that 'th r:

1) The control valve or ass valve position responds accordingly, or Verify that when tested pursuant to Specification 4.0.5 that each 2) The s a corresponding change in the me steam ADS valve is capable of being opened. ow, c) Performing a CHANNEL CALIBRATION of the accumulator backup compressed gas system low pressure alam system and verifying an alarm setpoint of 90
