3/4 LIMITINGCONDITIONS FOR OPERATION AND SURVEILLANCE REQUIREMENTS 3/4.5 EMERGENCY CORE COOLING SYSTEMS (ECCS)

SURVEILLANCE RE UIREMENTS Continued At least once per 18 months by:

1. Verifying automatic~atie~&interlock action of the RHR system from the Reactor Coolant System when the Reactor Coolant System pressure is above 600 psig.
2. A visual inspection of the containment sump and verifying that the subsystem suction inlets are not restricted by debris and that the sump components (trash racks, screens, etc.) show no evidence of structural distress or abnormal corrosion.
e. At least once per 18 months, during shutdown, by:
l. Verifying that each automatic valve in thc fiow path actuates to its correct position on a Safety Injection test signal.

Verifying that each of the following pumps start automatically upon receipt of a safety injection signal:

a) Centrifugal charging pump b) Safety injection pump c) Residual heat removal pump By verifying that each of the following pumps'eveloped head at the test fiow point is greater than or equal to thc required developed head when tcstcd pursuant to Specification 4.0.5.

1. Centrifugal charging pumps
2. Safety injection pumps
3. Residual heat removal pumps
g. By verifying the correct position of each mechanical stop for the following Emergency Core Cooling System throttle valves:
1. Within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> following completion of each valve strohng operation or maintenance on the valve when the ECCS subsystems are required to be OPERABLE.
