Radioactive waste arises with all uses of nuclear technologies and requires disposal for its safe long-term management. Site investigations to inform disposal site selection, design, environmental and safety assessment is central to implementing any disposal facility. This publication provides guidance on requirements-driven management of a site investigation programme for disposal and presents a broad range of tried-and-proven technologies used to conduct investigations and obtain required site data. Investigation approaches specific to different types of host rocks are presented and case studies on issues and challenges dealt with by Member States provide lessons learned. This publication will be of interest to senior decision makers, scientists and engineers, technical support organisations and regulatory authorities involved in disposal of radioactive waste.
