Concrete containers for containment of vitrified high-level radioactive waste: The Belgian Approach

Abstract
ONDRAF/NIRAS has selected the supercontainer as the preferred Belgian design for disposal of vitrified high-level radioactive waste. This supercontainer is base don the use of an integrated waste package composed of a carbon steel overpack surrounded by a concrete buffer based on Ordinary Portland Cement. An outer stainless steel liner encloses the concrete buffer. This buffer provides a favourable chemical environment for the overpack and radiological protection for the workers and should remain intact for on the order of a thousand years. For the choice of the cementitious buffer, two different compositions are being considered : a Self Compacting Concrete (SCC) and a traditional vibrated concrete (RPC). An intensive laboratory characterization program with large scale tests has been carried out. The obtained mechanical and thermo physical data are used to simulate the behaviour of the concrete buffer during the different stages of manufacturing by using a 3D thermal and crack modelling program. Through-going cracks in the concrete buffer should, at all times, be avoided.
