1-4.15 E".ERGENCY INSTRUCil0N I-4.15 Q l.0SS OF COMPONENT COOLING 1.0 PURPOSF 1.1 THIS INSTRUCITON PROVIDES GUIDELINES FOR PLANT CPERATION DURING AND FOLLOWING A FAILURE IN THE COMPONENT COOLING SYSTEM, EITHER DUE TO A LOSS OF FLOW, A P!PE RUPTURE, OR IN' LEAKAGE FROM ANOTHER SYSTEM.

1.2 SINCE THE COMPONENT C00 LING $< STEM IS AN ENGINEERED SAFEGUARDS SYSTEM AND IS ESSENTIAL TC ALL PHASES OF PLANT OPERATION, THIS INSTRUCTION DEALS WITH THE NECESSARY COURSE OF ACT10t TO BE TAKEN TO PLAct THE PLANT IN A SAFE CONDITION LAW IECHNICAL SPECIFICATION 3.7.'3.1, 2.0 INITIAL CONDITIONS 2.1 THE FOLLOWING WOULD BE INDICATIVE OF QUT-LEAKAGE FROM THE COMPCNENT COOLING SYSTEM:

2.1.1 DECREASING CCW HEADER FRESSURE.

2.1.2 INCREASING PUMP AMPS ON THE RUNNING CCW PUM?S. .

2.1.3 DECREASING COMPONENT CCOLING SURGE IANK LEVEL.

2.2 INCREASING TEMPERATURES CN CC' ?ONENTS SUPPLIED CCW IS INDICATIVE OF A DECREASE IN FLOW DUE TO A FLOW OBSTRUCTION, FotLING OF HEAT EXCHANGER TUBES, RUPTURE UPSTREAM OF THE COMPONENT, OR A LOSS OF PUMPS.

2.3 THE FOLLOWING WOULD BE INDICA'!VE OF INLEAKAGE TO THE CCW SYSTEM:

2.3.1 INCREASING ACTIVITY LEVEL ON EITHER HEADER.
