DISPOSAL OF HIGH-LEVEL RADIOACTIVE WASTES

This paper consists essentially of a sequence of statements (based upon generally accepted findings as presented eg. at the Symposium on Safety Assessment of Radioactive Waste Repositories, Paris, October, 1989" and upon specific experience from the Swiss programme) which are of direct relevance to the topic "Radiation protection and safety criteria for the disposal of HLW". The following areas will be touched upon: Existing performance assessment studies: principle features of relevance Current status of performance assessment methodology Role of performance assessment studies Uncertainty in performance assessment and confidence in the model predictions Judgment on the acceptability of performance assessment results It is hoped that these statements can provoke some interesting discussion during the workshop.
