The Low-Level Radioactive Waste Disposal Project Center of Japan Atomic Energy Agency will establish a sitting criterion and procedure in a fair and transparent manner to settle on a near surface disposal facility for low level radioactive wastes generated from research, industrial and medical facilities, based on "Plan Concerning the Disposal Business Execution". Therefore, reasonable conceptual design of the disposal facilities will be planned under premise conditions of sitting condition on natural and social environment, waste form condition including radioactive inventory and waste packages, and technical standards based on "Law for the Regulations of Nuclear Source Material, Nuclear Fuel Material and Reactors" and "Law concerning Prevention of Radiation Hazards due to Radioisotopes, etc." and so on. This report summarizes the results of the investigation on the sitting condition in these premise conditions for conceptual designs of the disposal facilities.
