CAUTION It is very important that the crane operator monitor the Dillon load cell when fuel is being moved. If the initial reading (established when the assembly is raised or lowered the first few inches) varies by +60 pounds the operator must stop fuel movement and evaluate the situation. Before re-initiating fuel movement the operator must determine the retson(s) for the variance and take corrective action, if tecessary.
7.3.11 When the appropriate slow zone clears, use the fuel hoist master control, at its slowest available speed, to raise the assembly out of the core.

" Fuel Gripper Zone Bottom of Basket" will illuminate.
7.3.15.2 If over the core, the-slowest available speed of the fuel hoist control must be used between slow zones to avoid serious damage to the fuel assembly. The operator must continually monitor the Dillon load cell while lowering an assembly and must stop fuel movement if the weight 1
drops more than 200 lbs. If a variance occurs, the operator must determine the cause and take corrective action before continuing the fuci placement. The appropriate slow zone if over the core, is " Bottom of Core".

8.4.20 Actuate the gripper hoist to lower the gripper and RCC assembly through the guide tube until the "Down" light illuminates.
8.4.21 Tighten the shaft clamp.
NOTE Observe the gripper hoist cable during lowering. Slack cable along with the "Down" light will indicate seating of the RCC assembly.
8.4.22 Verify the gripper. hoist is stopped by the Limit Switch when the RCC assembly is properly placed in the fuel assembly.
8.4.23 Hold the pneumatic selector valve down to energize the gripper piston which unlocks the flexure fingers and releases the RCC assembly.
8.4.24 Actuate the gripper hoist to raise the gripper through the guide tube until the "Up" light illuminates. The limit switch on the hoist will stop the gripper at the proper elevation.
8.4.25 Release the pneumatic selector valve to de-energize the gripper piston.
8.4.26 Loosen the shaft clamp.
8.4.27 Move the carriage south along the tracks until a carriage stop con-tacts the stationary stop at the south end of the tracks.
8s4.28 Tighten the shaft clamp.
8.4.29 Lower the revolving stop.
8.4.30 Using the Manipulator Crane, transfer the fuel assembly to its desired location, per Section 7.3 of this procedure.
