Thermal stresses in a repository for ultimate storage of high-level radioactive wastes
Description
An important factor to be considered in evaluating the suitability of a salt mine as a waste repository is the deformation behaviour of rock salt, as this is the predominant type of rock in this formation. Equations are presented and explained describing the elastic, plastic, and viscoplastic deformation mechanisms contributing to overall rock salt deformation, and use of these equations is made through a specially developed arithmetic method. As there are stratifications and discontinuties in the formation to be considered in the computation, additional criteria are to be taken into account in the integrity considerations, especially the figures of material equations for all other types of rock occurring in the formation.

Ein wichtiger Einflussfaktor ist das Deformationsverhalten von Steinsalz als dem Hauptgebirgsbildner. Zu seiner Beschreibung werden Stoffgleichungen zusammengestellt, die die elastischen, plastischen und viskoplastischen Deformationsanteile erfassen. Ein entwickeltes Rechenverfahren erlaubt die Benutzung dieser Stoffgleichungen. Die Existenz von Schichtungen und Diskontinuumserscheinungen im Salzgebirge macht es notwendig, in die Integritaetsbetrachtungen weitere Kriterien einzubeziehen, insbesondere die Stoffgleichungszahlenwerte fuer alle anderen beteiligten Gesteine enger einzugrenzen.
