Geological criteria for radioactive waste repositories

The isolation of radioactive waste in a geological rock unit requires careful evaluation to determine if radionuclides from the emplaced waste will eventually appear in the biosphere in amounts that would constitute a hazard. This document provides a comprehensive list of geological criteria and factors that can be used to derive the specifications that will be applied to each step of a geological evaluation process. Engineering and socioeconomic criteria that are influenced by geological factors are included. (DLC)
