Examination of Manipulator Size According to the Progress of Decommissioning Work

Abstract

In the decommissioning work of Unit 3 of the Fukushima Dai-ichi NPS, it is planned to remove fuel debris. Because of the high radiation levels, fuel debris must be removed using a remote-controlled manipulator. However, at present, there is no manipulator suitable for removing fuel debris. To prepare for designing a manipulator suitable for taking out fuel debris, a simulation of removing fuel debris has done to examine optimum size of the manipulator.
