Das Projekt "Bentonitbarrieren in integrierten Sicherheitsanalysen" wird vom Umweltbundesamt gefördert und von Gesellschaft für Anlagen- und Reaktorsicherheit (GRS) gGmbH - Fachbereich Endlagersicherheitsforschung durchgeführt. The overall objective of the project is to assess the state of the art in the treatment of bentonite barriers in Integrated Performance Assessments of repositories in clay and in granite rock, evaluation the capacity and consistency of methods and data available to convincingly justify the capacity of bentonite to perfrom ther assignet safety functions. Bentonite barriers are a fundamental component of repositories in granite and clay host rock. 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.
