High Polymer-Based Composites for Spent Nuclear Fuel Disposal Containers

Abstract

The concept proposed by Atomic Energy of Canada Limited for the deep underground disposal of spent nuclear fuel foresees the use of metals or alloys such as copper and titanium for the fabrication of the storage container. The choice of these materials is based mostly on their good resistance to adverse environments and corrosion in particular, such that they are believed to be capable of keeping their integrity over the many centuries the radioactive materials have to be kept isolated from the biosphere. The authors have started a research project aimed at proposing alternative materials for the fabrication of the containers such as high polymer-based composites known for their excellent mechanical and chemical resistance properties. This paper will present the results obtained so far on the radiation damage and the heat transfer aspects of this special application.
