ABSTRACT:The present study uses Geographic Information System(s) (GIS) as a spatial decision support tool to select potential sites in Egypt for deep geological disposal for spent radioactive fuel. A specific weight is given to each criterion according to its relative influence on the process of decision making. The results from the application of the presented methodology determine the relative suitability of sites for deep disposal of radioactive wastes. These sites are ranked in descending order to help decision-makers in Egypt. The present study aims to provide a baseline for more detailed technical analyses for the selected sites.
