Clean-up activity of spent fuel powder (UO powder) in mechanical treatment cell was performed for the purpose of the preparation of decommissioning at TRP. For the clean-up activity, we selected an inexpensive vacuum cleaner and made tools, that was improved taking into account of use by means of a crane or a manipulator in the high dose cell, and applied it after a mock-up test. We report our experience and knowledge provided through this clean-up activity.

All the spent fuel stored in the Tokai Reprocessing Plant is transported to the overseas reprocessing plant. When spent fuel transportation, we use dry type cask instead of wet type cask. Therefore, equipment of the wet type cask is not used. And the equipment is some possibility of interfere with cask because the equipment is stored in the transport route. So, we were dismantled receiving and storage process equipment as preparation work for spent fuel transportation. In dismantlement work, we selected cutting equipment after scrutinizing size and shape of equipment, contamination and workability. Moreover, we have taken safety measures during work such as fire prevention and contamination control. As a result, the work was completed as originally planned.
