Abstract
After the CEC PAGIS project (for vitrified waste), the PACOMA project started at the end of 1987 for medium level and alpha waste. The CEA-IPSN has been in charge of the granite option. For the PACOMA project, a representative inventory of waste has been built up, a repository concept (with one variant) has been defined and an adaptation of the near field module CONDIMENT of the safety evaluation code MELODIE, has been made in order to take into account the particularities of cemented waste with respect to the vitrified waste. For the normal evolution scenario, best-estimate calculations have been performed for a reference site (the french Auriat site) which is an outcropping granite and for two variants, the first one representing a coastal granite formation (Barfleur) and the other one, a granite with a sedimentary cover (notional British site). Sensitivity and uncertainty analysis have been performed with a 2D modelling of the geosphere (module METIS of the MELODIE code) instead of the 1D modelling (stream tube) previously used in the PAGIS project. After a general presentation of these points, the main results, namely the dose rates obtained through deterministic calculations, and the most important geosphere parameters, are presented.
