An investigation has been carried out of aspects of the waste management of spent light water reactor fuel by direct disposal in a deep geological formation on land.
The areas covered are:
interim dry storage of spent fuel with three options of preconditioning;
conditioning of spent fuel for final disposal in a salt dome repository;
disposal of spent fuel (heat generating waste) in a salt dome repository;
disposal of medium and low level radioactive wastes in Konrad mine.
Dose commitments, effluent discharges and potential incidents were not found to vary significantly for the various conditioning options/salt dome repository sites.
Due to uncertainty in the cost estimates, in particular the disposal cost estimates, the variation between the three conditioning options examined is not considered as being significant. The specific total costs for the direct disposal stategy are estimated to lie in the range ECU 600 tp 700 per kg hm (basis 1988).
