This report describes the result of conceptual design study concerned with "High Radioactive - Solid Waste Treatment Facilities, "which will be planed for the purpose of volume reduction and stabilization of High Radioactive - solid wastes generated and stocked in the O-arai Engineering Center of PNC. In this conceptual design study the basic process of the facilities, which are sufficient to treat each waste and develop technologies, are clarified. This report consist with: (1)Clarification of waste to be treated. (2)Study on the treatment technology and process. (3)Conceptual design of facilities and equipment. (4)Estimation of construction cost and schedule.

Feasibility experiments were conducted to develop a novel inspection method for non-destructively detecting corrosion on the inner surfaces of radioactive waste containers (steel drums) and nuclear fuel material containers (stainless steel cans) using active thermography with an infrared camera (IC). The experiments confirmed that a non-cooled IC could detect corrosion with a minimum diameter of approximately 15 mm in steel drums. Regarding stainless steel cans with simulated inner corrosion (10 mm diameter), corrosion was detectable when the outer surface temperature was 5 degrees Celsius and 40 degrees Celsius, but detection became difficult at 70 degrees Celsius.
