REFUELING MACHINE OPERATION SYSTEM OF FUEL ASSEMBLY

摘要

PURPOSE: A refueling machine operation system of a fuel assembly is provided to offer a displacement position of nuclear fuel refueling machine without the interference of nearby nuclear fuel assembly by automatically detecting reloading status of the nuclear fuel assembly in the core without additional sensor. CONSTITUTION: A load sensor senses the load applied to the wire rope. A pincers state sensor senses state as to whether the pincers is in closed state or open state. A human-machine interface apparatus(220) indicates all seating positions which can be loaded with the nuclear fuel assembly as a plurality of cells. The human-machine interface apparatus indicates the cell as the withdrawal state or the loading state.
