JAEA has promoted near surface disposal project for low-level radioactive wastes generated from research, industrial and medical facilities. JAEA has carried out public information about the project. When some town meetings are held toward mutual understanding with the public more detailed and clear explanations for safety management of the project are needed especially. Therefore, the information provision method to make the public understand should be reviewed. Moreover, a survey should be carried out in order to get a sense of what the public knows, what it values and where it stands on nuclear energy and radiation issues, because the social environment surrounding nuclear energy and radiation issues has changed as a result of the accident at the Fukushima on March 11, 2011. This review clarified the points to keep in mind about public information on the project, and that public recognition or understanding toward nuclear energy and radiation was changed before and after the accident.

Sub-surface disposal is one of the disposal methods for low-level radioactive waste in Japan. It will operate below the generally used depth domestically. The waste disposed by this method is assumed to be core internals and part of TRU (the transuranium elements) waste from reprocessing and MOX (mix oxide fuel) fuel fabrication facilities. These contain the waste generated as a result of research activities, too. In order to establish a safety regulation for the disposal, a case study of the overseas disposal is useful. The similar disposal plan of Japan has been considered or already operated especially in Finland and Sweden. Therefore, in this study, we investigated current status and concept of appropriate sub-surface disposal in both countries as below. In Finland, waste management and disposal methods are regulated by Nuclear Energy Act and national policy. Low and intermediate level wastes are disposed into the cave in bedrock at each nuclear power plant site. In Sweden, safety handling and disposal of waste are regulated by Act on Nuclear Activities. The disposal of low and intermediate level wastes has been operated under the seabed. This operation is carried out by a joint company which the nuclear companies have formed. In addition, we reported a site selection, burial depth and financial plan etc. in both nations.

Japan Atomic Energy Agency (JAEA) is supposed to draw up the plan for the disposal program of the very low-level radioactive waste and low-level radioactive waste generated from medical, industrial and research facilities. For instance, there are these facilities in JAEA, universities, private companies, and so on. JAEA has to get to know about the waste and its acceptance of other institutions described above because it is important for us to hold the licenses for the disposal program regarding safety assessment. This report presents the basic data concerning radioactive waste of research institutes etc. except RI waste, domestic and foreign information related to acceptance criteria for disposal of the low-level radioactive waste, the current status of foreign medical waste management, waste acceptance, and such. In this report, Japan's acceptance criteria were summarized on the basis of present regulation. And, the criteria of foreign countries, United States, France, United Kingdom and Spain, were investigated by survey of each reference. In addition, it was reported that the amount of waste from laboratories etc. for near-surface disposal and their characterization in our country. The Subjects of future work, the treatment of hazardous waste, the problem of the double-regulation (the Nuclear Reactor Regulation Law and the Law Concerning Prevention from Radiation Hazards due to Radioisotopes and Others) and the possession of waste were discussed here.
