Description	The Centre of Experimental Geotechnics (the Faculty of Civil Engineering of the Czech Technical university in Prague) has been realising from 2012 to 2015 a project for the Radioactive Waste Repository Authority (SÚRAO) comprising a demonstration experiment Mock-up Josef. The experiment is focused on physical modelling of the behaviour of a bentonite layer loaded in a way similar to the conditions in the plan-ned deep repository for radioactive waste. Apart from the action of the rock environment and groundwater, bentonite is loaded by heat in the experiment. The thermal loading induced by a heater simulates the radiation of heat from the repository envelope containing the spent nuclear fuel. Excessive heating may lead, for example, to mineralogical changes in the bentonite. The change in mineralogy may cause the desta-bilisation of a part of the repository system – the reduction of the sealing capacity of bentonite. Physical models are important for the verification and mathematical modelling of the disposal system stability. The Mock-up Josef insitu physical model will in addition provide experience in the construction and operation of an experiment till now unrealised in the Czech Republic. The data obtained from the model will allow for more accurate simulation of anticipated processes in the deep repository. The paper informs about the Mock-up Josef experiment structure and some results obtained from the extensive monitoring of the installed model.
