Abstract

During the cut and dismantling process of HANARO irradiated instrumented capsule(03M-06U), a little different phenomenon like a jamming was observed and occurred. So to release jamming between outer pipe and inner thermal media, the outer pipe will be cut piece by piece by capsule cutting machine installed in M2 hot cell until the outer pipe was eliminated or reduced as we could. It is assumed that this kind of problem was occurred following reasons: 1) This capsule has probably a problem during manufacturing process at shop before irradiation. 2) The gap between outer pipe and thermal media is not enough to meet design criteria for thermal expansion during irradiation at HANARO
