OSTI ID:4840390
A grab is designed for removing extraneous objects from fuel element or control rod channels in heterogeneous reactor cores. The grab comprises an outer tube, an inner tube rotatably mounted within the outer tube, and chains connecting the ends of the tubes. In the open position, the chains hang in loops near the sides of the channel; by rotation of the inner tube, the chains are drawn to a taut position, thereby trapping any object situated within the grab.
