Integrated head assembly for assembly disassembly and precision gripping of randomly arranged fuel rods for remote dry withdrawal of spent fuel rods

摘要

The present invention draws the fuel rods from the spent fuel assembly having high radioactivity within a limited shielded space and arranges them densely and packs them in a storage or disposal container to save space for storing or disposing of spent fuel. In order to reduce the shielding space and work efficiency by implementing the lower stationary dismantling device of the spent fuel assembly and the precision fuel closing device for fuel rod extraction in one device (head assembly), The present invention relates to an apparatus capable of increasing the stability of the work.
