THE LONG-TERM SAFETY OF REPOSITORIES

The results of safety assessments expressed as risks or doses may be t aken only as indicators of the safety of a repository system over prol onged periods of time. Using a combination of safety indicators togeth er with natural analogs can make a major contribution towards reducing uncertainties in long-term safety assessment. In this report, an isol ation potential is demonstrated for the German Konrad and Gorleben rep ository projects which extends from the genesis of the host rock and o f the geological system to the present. Comparable studies of other si tes are unable, for that reason, to result in findings better than the se.
