The basic policy for the decommissioning of the nuclear reactor in Japan was shaped in the 1990s. In the policy, it is premised that the nuclear power stations will be dismantled and removed after the safe store of the reactor from 5 to 10 years. Fugen, is the proto-type heavy water moderated, light water cooled, pressure tube type reactor with 165 MWe and has been shut downed 25 years operation. The program for decommissioning of Fugen had been prepared, and it was approved on Feb. of this year. Following the approval, we initiated to dismantle part of the facilities. It is expected that the whole decommissioning will be completed until 2028. In this paper, the basic policy for the decommissioning in Japan is outlined. The decommissioning program of FUGEN and relating R&D are also described.
