A COMMON METHODOLOGICAL APPROACH BASED ON EUROPEAN DATA AND MODELS
Since 1982 a joint study has been launched by the CEC with the participation of national institutions in the E.C., aiming at a Performance Assessment of Geological Isolation Systems (PAGIS) for HLW disposal. This document is a summary of the first phase of the study which was devoted to the collection of data and models and to the choice of an appropriate methodology. To this purpose, real or notional sites have been chosen, which are representative of three types of continental geological formations in the E.C.: clay, granite and salt (although the choices imply no commitment of any kind about their final use). Moreover, sub-seabed areas have also been identified. The study covers the following items: Basic data on waste characteristics, site data and repository designs; Methodology, which allows sensitivity and uncertainty analyses to be performed, as well as the assessment of radiation doses to individuals and populations; Preliminary modelling of radionuclide release and migration through the geosphere (near and far field) and the biosphere following their various pathways to man; Selection of the most relevant radionuclide release scenarios and their probability of occurrence. Reference values have been selected for the basic data as well as variants covering the various options which are under consideration in the different countries of the E.C.
