APPARATUS FOR EXTRACTING NUCLEAR FUEL ROD WIHTOUT END CAP FROM NUCLEAR ASSEMBLY

摘要

PURPOSE: An apparatus for extracting a nuclear fuel rod from a nuclear fuel assembly during losing an end closure is provided to prevent deformation of a nuclear fuel rod by including an anti-deformation pin. CONSTITUTION: An inner extraction load(620) is movably formed on the inside of an outer extraction load(610). An exterior gripper(100) includes a gripper combining end part and a gripper tapered pipe part. The upper part of the exterior gripper is combined with the end part of the inner extraction load. An anti-deformation pin(200) is inserted into the inside of a nuclear fuel rod without an end closure. The anti-deformation pin prevents deformation of the nuclear fuel rod by pressure to the center.
