. EMERGENCY CORE COOLING SYSTEMS SURVEILLANCE REQUIREMENTS (Continued)
- 2) Low pressure setpoint of the:
(a) LPCI A and B subsystem loop to be 1 38 psig.
(b) LPCI C subsystem loop and LPCS system to be 1 22 psig.
(c) HPCS system to be 1 18 psig.
b) Header delta P instrumentation and verifying the setpoint of the HPCS system and LPCS system and LPCI subsystems to be 1.2 0.1 psid change from the normal indicated AP.
- 3. Verifying that the suction for the HPCS system is automatically transferred from the condensate storage tank to the suppression pool on a condensate storage tank low water level signal and on a suppression pool high water level signal.
- d. For the ADS at least once per 18 months by:
- 1. Performing a system functional test which includes simulated I automatic actuation of the system throughout its emergency operating sequence, but excluding actual valve actuation.
- 2. Manually opening each ADS valve when the reactor steam dome pressure is greater than or equal to 100 psig* and observing that either:
a) The control valve or bypass valve position responds accordingly, or b) There is a corresponding change in the measured steam flow.
(InseAT) x The provisions of Specification 4.0.4 are not applicable provided the surveillance is performed within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after reactor steam pressure is adequate to perform the test.

- 3. Performing an extrapolated pressure decay test on the ADS air system to demonstrate system pressure will be maintained for 7 days at a value 2: 110 psig without makeup air available.
- 4. Verifying within 31 days after obtaining the representative sample that a laboratory analysis of the instrument air supply to ADS shall be determined to contain:
- 1. particle size less than or equal to 50 microns
- 2. total hydrocarbon less than 1 ppm
- 3. moisture content less than or equal to -40 0F dew point at 100 psig.
