In the next Fast Breeder Reactor (FBR) in Japan, duplex pipes are planed to be used for pipes in the cooling system. It can improve the safety of the FBR, but makes maintenance hard, especially for the inner pipes. Moreover, the temperature of the environment is 200 degrees. In this research, we develop an inspection and repair robot for an inner pipe at high temperature. In the system, we adopt a wheel drive system on rails attached inside of the outer pipe to reduce the weight. This paper introduces the overview of the system and shows experimental results at room temperature.
