Summary

Among the facilities requiring decommissioning are underground facilities. These require special consideration and are the subject of this publication. Firstly, due to their poor accessibility, there are significant difficulties in physical and radiological characterization, deployment of decontamination techniques, and physical disassembly and removal. Secondly, these types of components are present in a large number of nuclear installations. However, early nuclear design and construction practices often did not consider or incorporate eventual decommissioning requirements in their design considerations and these requirements were not commonly enforced in the early nuclear era. This is also true for those facilities situated in countries that do not have sufficient experience/expertise in performing decommissioning. Thirdly, a comprehensive assessment of the literature on nuclear decommissioning of underground components shows that this subject has not yet received any systematic coverage, despite the technical difficulties that have been encountered in actual projects to date. In fact, the literature on this subject is comprised of rather sporadic case histories. This publication is intended to draw attention to a neglected field and to collate/condense sporadic information into an overview of important factors and practical guidance.--Publisher's description.
