ABSTRACT

Many disposal sites have been suffered from radionuclide release problems, which lead to land contamination. Various remediation procedures have been developed during the past decade. Selection of remediation techniques is dependant mainly on quantity and quality of radioactive contamination. For that reason, the understanding of the factors that control the degree of contamination of any land should be the start of this problem. The present work aimed to construct the base of a new mandatory chapter in the safety analysis report that discuss and predict quantatively and qualitively the possible release from disposal site. The objective of this chapter is to prevent, restrict, and/or remediate economically the contamination that can be occurred. In the present work, a generic disposal system was evaluated. The radio-elements, which can contaminate the area before their decays, are determined by a screening process. Knowing that the mode of radionuclide migration from a disposal site is one from the important factors that control the contamination problem; migration activity of the selected radionuclides is assessed by considering instantaneous and continuous modes release of radionuclides from the disposal site. Finally, the elementary analysis steps demonstrated in this study will be concluded as the proposed items in the new chapter.
