Advisory Committee on Nuclear Fuel Cycle Backend Policy reported the basic approach to the RI and Institute etc. wastes on March 2002. According to it, radioactive waste form medical, industrial and research facilities should be classified by their radioactivity properties and physical and chemical properties, and should be disposed in the appropriate types of repository with that classification. For the radioactive waste containing comparatively high radioactivity generated from reactors, NSC has established the Concentration limit for disposal. NSC is now discussing about the limit for the radioactive waste from medical, industrial and research facilities containing comparatively high radioactivity. Japan Nuclear Cycle Development Institute (JNC) has studied about the feasibility and the cost of the disposal for radioactive waste from medical, industrial and research facilities. This study was started to renew to latest data of the radioactive waste. And at the point of shielding from radiation, the waste was categorized by activity of nuclide in waste container. Then the safety assessment and the prediction of cost of the disposal performed.
