The present invention relates to an in-core instrumentation using a shield tube and, more specifically, to an in-core instrumentation using a shield tube inserted and fixed with neutron detector lead cables, a signal compensation detector, and a thermocouple in multiple radial cable insertion grooves which is formed in the outer peripheral surface and formed to include the shield tube continuously connected with the cable insertion grooves in the longitudinal direction. The an in-core instrumentation with a simple assembly can remove a filler cable required for fixating a neutron detector and continuously connect the same shield tube by which any one of the neutron detector lead cables passes through a mounting groove of the detector formed through the center of the shield tube in order to insert and fix one neutron detector to the mounting groove of the detector for the respective shield tube. |
