Fuel gripping device for spent fuel shearing device

摘要

(57) [Abstract] is [Purpose] The hanging bracket eliminates the drive for rotating the structure of the fuel gripping device is simplified, reducing the frequency of production cost and failure. [Configuration] Putsushiya one allowed to advance toward the handling head portion 2 of the spent fuel, is multiplied by abutting the distal end portion of the bracket 1a a front end surface of the Putsushiya 1 at the same time when you insert into the handling head portion 2 in the handling head portion 2 It is to be, The containing part of the fuel of the spent fuel Peretsuto is fed little by little to shear position of the shearing device, and dissolved unnecessary portions of the spent fuel is to be fed to the shear position of the shearing device, and let turned the Putsushiya 1 to retreat, is multiplied The front end portion of the bracket 1a is engaged with the hook portion 2a of the handling head portion 2, and pull back the spent fuel from the shearing device. Then, when the spent fuel is pulled back to a predetermined position, over and let ride the roller 1c of the bracket 1a to release bracket 4 on the support surface 3, multiplied by rotating the bracket 1a in the withdrawal direction, the hook 2a its tip It moved away from.
