Abstract

The PACOMA (Performance Assessment of Confinement for Medium and Alpha waste) project is intended to evaluate the suitability of clay, granite and salt formations for the disposal of conditioned alpha and medium-level radioactive waste. In this report, CEA-IPSN presents the database and the results of evaluating the radiological consequences associated with the disposal of alpha-bearing waste in a deep granite formation. Two repository concepts and three sites are examined. The methodology adopted for the PAGIS project is used for carrying out the deterministic calculations of radiological consequences in the case of normal evolution scenarios and in altered evolutions, as well as for sensitivity analysis of results to the calculation parameters and for uncertainty studies. The calculation of individual doses in the case of normal evolutions show, after a first peak due to I-129, Se-79 and Tc-99 after some hundred thousands years, a maximum, which is reached only after several million years. In all cases, these maxima are largely lower (by a factor of 1000 at least), than the limit recommended by the IRCP.
