CUE: Once the candidate identifies the equipment that must be manipulated, role play as the Unit Supervisor as required.
IF the isolation plan includes CC1, The operator in the field is unable to close CC1 and the CCW leak continues. Identify additional components which MUST be manipulated to isolate the CCW leak.
IF the candidate has already expanded the isolation points, evaluate the boundary to ensure the leak has been isolated (See JPM Step 3).

PERFORMANCE STEP: Identify valves required to isolate CCW leak
........C........
STANDARD: Uses identified prints to isolate CCW leak.
NOTE: Other components may be identified, if that is the case, these are to be treated as NON-CRITICAL portions of this step.
NOTE: The following valves are not required to be listed for the following reasons.
- The Non-Essential valves will Auto Transfer. CC5095, CC5097, and CC2645 will Auto close when CCW Pump 1 is stopped.
- SW233, CC121, CC662, CC244 are Normally Closed (NC) valves.
- When CCW Pump 3 is aligned as 2, CC35 and CC4 are NC.
- CC248, CCW Corrosion Test Piping Line 1 Outlet Isolation is not a credible pressure source. This line is normally fed from CCW Train 1 discharge header.
However, with CCW Pump 1 off, there could be backflow from MUP 1 Cooler, through a throttled valve (CC129), HPI 1 Bearing, test coupons, small diameter piping, and elevation changes.
The following identify the additional MINIMUM valves to be closed to isolate the leak based on CC1 failing to close.
- CC123, CCW Surge Tank Isolation (from Sheet 3)
- CC172, CCW From Decay Heat Cooler 1 Outlet Iso
- CC243, CTMT Gas Analyzer 1 Normal Source Outlet The following identify the MINIMUM valves to be closed to isolate the leak if CC32 was NOT used as an isolation.
