탈피복 장치의 원격 유지보수 시험

In this study, we developed a decladding device which separates a simulated spent fuel rod with 250 ㎜ length into the pallets and the pieces of the hulls. To improve the performance of the equipment, we devised mechanisms to prevent the rod cut from being exposed or bounced into the hot-cell, to reduce the operation time, and to insert the rods automatically. The decladding device has some features such as the semi-automation of the loading/unloading procedures of the rod-cut, the automatic separation of the pellets and clad, and remote operability and maintainability, etc. The performance of the slitting device was tested by using the simulated fuel rod-cut. As a result of the performance test for some mockup fuel rod cuts in the ACP(Advanced Spent Fuel Conditioning Process) facility, it was verified that the decladding device could be applied to the actual fuel rod cut. Furthermore, the results of this study could be used for the design of a scale-up facility in the future.
