The use of the Mock-up-Cz physical model in the design of engineered barriers

摘要

A fundamental challenge concerning research into high-level radioactive waste disposal is the construction design of natural and engineered barriers capable of preventing the leakage of hazardous radionuclides over a period of roughly 100 thousand years. In order to obtain the information enabling the design of such a construction, it is necessary to employ all the experimental tools and procedures available including physical modelling. The most relevant model types for this task have been found to be those made at a scale of 1 : 1, referred to as mock-up models. Information on the construction, operation and dismantling of a vertical model of a bench-scale buffer mass test of Czech smectitic clay employing the KBS-3V system modification forms the main subject matter of this paper.
