AbstractAbstract
[en] Long-term dry storage and direct geological disposal of spent nuclear fuel are two options for nuclear waste management studied in the framework of the 1991 French law. This report briefly describes the source term models developed for dry storage and geological disposal of spent fuel. These models have been developed in the framework of the research program on the spent fuel long term evolution (PRECCI project). These models are called operational because they are based on a simplification of evolution processes by using a pessimistic approach when uncertainties subsist. Potential improvements have been identified. (authors)

L'entreposage a sec de longue duree et le stockage geologique direct de combustibles irradies sont deux options de gestion des dechets nucleaires de haute activite et a vie longue etudiees dans le cadre de la loi Bataille. Ce document presente de maniere synthetique les modeles de relachement des radionucleides pour un entreposage a sec ou un stockage geologique de combustibles uses. Ces modeles operationnels ont ete developpes dans le cadre du Programme de Recherches sur l'Evolution a long terme des Combustibles Irradies. Ils reposent sur une simplification des mecanismes d'evolution du combustible use en adoptant une approche conservative. Des voies d'amelioration ont ete identifiees pour reduire les conservatismes.
