Abstract (Englisch)

Bentonite barriers are a fundamental component of repositories in granite and clay host rocks. The project will analyse and integrate the numerous developments achieved in the study of these barriers in order to improve their treatment in Integrated Performance Assessment. Current repository concepts will be reviewed and referent cases common to all the participants will be selected for the project. Available information on FEPs will be assessed and processed in order to evaluate the bases for decisions in IPA. Assessment codes at process and integrated level will be analysed and upgraded where necessary. New more advanced calculations at process and integrated level will be carried out, in order to verify model performance and to evaluate the sufficiency of available assessment methods. Sensitivity and optimisation analyses will be performed.
