3.1 Purpose This procedure only provides instruction in the off"normal operation of the Component Cooling Water Process Monitors. It does not provide instructions for corrective action for the C.C.W. systems.
These are covered by Off-Formal Operating Procedure 2-0310031, C.C.W. EXCESSIVE ACTIVITY.
3.2 Discussion The C.C.W. process monitors are designed to provide an indication of the radioactivity in either HEADER, and to alarm when the radioactivity reaches or exceeds the alarm setpoint.
Radioactive in leakage could occur at:
3.2.1 Letdown Heat Exchangers 3.2.2 Sampling System Heat Exchangers 3.2.3 Shutdown Cooling Heat Exchangets 3.2.4 Contaminated Make Up Water
4.0 SYMPTOMS
4.1 Visual and audible alarms on the Control Room RMS safety cabinets and the three (3) system Operators Terminals.
4.2 Respective channel ALERT, EIRE, or PAIL elates.
4.3 Increasing activity as noted on the respective channel recorders and on the channel graphic display histograms.

5.0 INSTRUCTIONS
5.1 Immediate Automatic Action 5.1.1 The CCW surge tank vent valve (RCV-14-1) diverts from atmosphere and realigns to the chemical drain tank upon actuation of a HIGH or FAIL alarm.
5.2 Immediate Operator Action 5.2.1 Acknowledge the alarm(s) and notify the Chemistry Department.
5.3 Subsequent Operator Action 5.3.1 The CCW A & B headers are normally operated in a cross" connected mode through the "N" header isolation valves.
A leak on either header should result in a trend increase in the other header.
Check the CCW radiation monitor recorder trace.
5.3.2 Verify that the CCW surge tank vent valve is aligned to the Waste Management System.
5.3.3 Consult Off-NormalOperating Procedure 2-0310031, CCW Excessive Activity.
5.3.4 For an energized Fail alarm, the channel should be considered out of service.
Consult the Plant technical specifications and notify responsible personnel to effect repairs.
Note that when the system is operated 3.n the cross-connected mode (see 5.3.1), radiation monitoring capability is achieved via the other CCW rad monitor.
