Various Research and Development (R and D) efforts related to the retrieval of damaged fuel debris at Fukushima Daiichi Nuclear Power Plant in Japan have been made since the accident occurred in March 2011. Since 2012, the Primary Containment Vessel (PCV) Repair Project has been one of the major improvement tasks required in the reactor buildings in order to start fuel debris retrieval activities. The primary purpose of this project is to create a water boundary in the lower sections of the PCV using remote handling methods. A designated long reach remote manipulator for this project, called the Fukushima Repair Manipulator (FRM), has been developed to perform inspection, light demolition, and deployment of various tools to supply sealing material to fill the vent tubes as a part of the PCV Repair Project. The FRM is a single hydraulic manipulator which has 7 degrees of freedom, over 9 m reach, tool change capability and a payload of 50 kg at maximum reach. These features provide a safe, robust, efficient and allow for flexible operations in limited access and visibility around the operating area. This paper will provide a system description of this manipulator and planned remote operations for the PCV Repair Project. (authors)
