Low level liquid waste generated from reprocessing of spent nuclear fuel in the Tokai Reprocessing Plant solidified with bitumen from 1982 to 1997. About 30,000 of bituminized wastes were produced, and stored in the storage facility. Recently, the leakage phenomenon due to the corrosion of bituminized waste drum occurred in the other nuclear facility. Based on the malfunction event, we have advanced the development of observation device for grasping soundness of the bituminized waste drums stored in the storage facility. This paper is reported about our effort to develop a remote observation device of the bituminized waste drums stored in the storage facility and the observation results with the developed device.
