In Japan, low-level radioactive wastes generated from research institutes, universities and medical institutions are continuously stored without being buried. Therefore, the Japan Atomic Energy Agency (JAEA) has been an implementation body of the burial project of the radioactive wastes from research facilities. In this report, the characteristics of the wastes and the conceptional design of the JAEA burial facilities are introduced, and the current status of the study on the radioactivity concentrations corresponding to dose criterion for trench disposal and pit disposal is also presented.
