Classification of radioactive wastes and their derived release limits FROM near surface repository: Proposed approach

In Egypt, according to the new Nuclear Law No 7 for 2010, and the presidential decision of establishing nuclear power plants, national authorities with defme responsibilities have been designated. Therefore, such authority is improving its technical infrastructure in terms of national processes and systems. Because the basic goal of radioactive waste management is to protect human and environment, the safety features of the waste management system should be considered. To simplify the management processes for the various types of radioactive wastes produced from different uses, a classification system of these wastes should be established. This classification must represent or correlate to the relevant features of their constituent elements. In other words, the construction of system for waste classification desires to simplify and to promote proper management. In case of present work, classification of radioactive wastes based on ALI values is a proposal approach for the near surface disposaL ALI; Annual Limit Intake is defmed as the smaller value of intake of a given radionuclide in a year by the reference man that would result in a committed effective dose calculated by the International Commission on Radiological Protection (ICRP). The ALI values are frequently used to fmd derived levels of concentrations of radionuclides for the purpose of implementing control measures in practice. ALI is used as indicator for hazard level of radionuclides.
