NUCLEAR FUEL TRANSFER TUBE BLIND FLANGE CLAMPING DEVICE

摘要

PURPOSE: An apparatus for clamping a flange blocking a nuclear fuel transfer pipe is provided to minimize radiation doses since a flange blocking a nuclear fuel transfer pipe is opened and closed rapidly using a clamping device. CONSTITUTION: A fastening flange(10) is combined with an outer circumferential surface of an end portion of a nuclear fuel transfer pipe penetration sleeve(11). A blocking flange(20) is closely connected with the fastening flange. A clamping device combines the fastening flange with the blocking flange closely. A first clamping portion(31) is inserted into a part of the outer circumferential surface of the blocking flange and the fastening flange. A second clamping portion is inserted into the rest of the outer circumferential surface of the blocking flange and the fastening flange. A compression coupling member presses and couples first and second clamping portions.
