FEASIBILITY STUDIES FOR A RADIOACTIVE WASTE REPOSITORY IN A DEEP CLAY FORMATION
This report assesses the feasibility of deep geological disposal of long lived, heat-emitting radioactive wastes produced from the Italian nuclear power programme. Disposal is envisaged in argillaceous formations of medium plasticity at depths between 200 and 3000 meters. Thermal and geotechnical data, together with information on cost and feasibility of construction techniques are used to devise two conceptual designs (repository or deep borehole disposal) for a facility to contain all the high level wastes arising from a 10 GWe power programme. Alternative designs and their merits are discussed and assessed. The two reference designs are used to construct a simple model of long-term performance and safety of the proposed disposal system. Recommendations are made for further work required to develop these concepts into an operational facility. It should be borne in mind that since no definite area or site has yet been identified for a disposal facility, all considerations are purely generic. Consequently data on rock properties and geological environment represent average values or best estimates for those likely to be encountered in the regions currently being considered as suitable for deep disposal purposes, and several broad assumptions have had to be made. However, the designs presented could be adapted without difficulty on a site specific basis when the results of further research become available.
