摘要： A handling system for an in-core detector thimble tube of a reactor is disclosed. The handling system serves to withdraw and retract a thimble tube so as to provide a movement path of a movable detector used to measure a neutron flux within a reactor. For this, the handling system basically includes a thimble tube withdrawing/retracting device, which grips the thimble tube using a plurality of synthetic resin pinch rollers to withdraw and retract the thimble tube without any damage to the thimble tube, a thimble tube tensioning device, which applies a constant tensile force to the thimble tube to prevent the thimble tube from shaking or bending upon withdrawing/retracting operations, and a thimble tube platform, which temporarily keeps the withdrawn thimble tube at a fixed position without a risk of shaking of the thimble tube and provides a movement path of the thimble tube tensioning device. With automatic withdrawal/retraction of the thimble tube without damage provides advantages of an extended thimble tube exchange interval, improved safety of system facilities, reduced labor costs and working time, and reduced worker radiation exposure, shortened precaution/maintenance period, and enhanced reactor use efficiency.
