The Effect of Variations in Parameter Values on the Predicted Radiological Consequences of Geologic Disposal of High-Level Waste

Abstract

A preliminary assessment of the radiological consequences of geologic disposal of high level waste carried out at the National Radiological Protection Board identified several areas where further research is required before this disposal option can be fully evaluated (1). This paper summarizes an analysis of the sensitivity of the results of the preliminary assessment to the assumptions made and the values of the parameters used (2). The purpose of the analysis was to clarify research objectives rather than to derive the possible range of potential doses. The numerical results must be viewed in this context and should not be regarded as representative of those which would be obtained for a specific repository.
