Fugen Decommissioning Engineering Center (herein after called as "FUGEN") obtained the approval of the decommissioning program on February 2008. FUGEN has been carrying out decommissioning works based on its decommissioning program since then. Now is in initial stage, the dismantling works was launched in turbine system whose contamination was relatively low level and their various data have been accumulating. And the draining heavy water, tritium decontamination and transferring of heavy water were carried out safely and reasonably. The preparation for the clearance system and the research and development works for the reactor core dismantling have been progressed steadily as well. Meanwhile, FUGEN has affiliation with local industries and universities for collaboration research, and has exchanged the decommissioning information with domestic and overseas organizations continuously.

The waste which does not need to be treated as a radioactive material by the clearance system shall be recycled in FUGEN. However the commencing time of the radioactive waste disposal facility operation isn't clear, though, it is important to operate the clearance system and take out the dismantled objects from FUGEN in order to push forward decommissioning as much as possible at the current moment. Although the dismantled objects have temporarily been stored in the facility, the space for the storing is getting reduced year by year. So, the dismantled objects need to take out by the clearance system in early time. In poster presentation, the preparation for the clearance system and its operational issues in FUGEN will be reported.
