Abstract
ABSTRACT The development of a High Integrity Container (HIC) made of Reactive Powder Concrete (RPC) for interim storage of radioactive waste is presented, namely its impact performance. RPC was chosen for durability reasons, then the remaining integrity of the container after a drop test was assessed numerically. The constitutive model developed is suited to describe the behaviour and damage of concretes under high loading rate. RPC is modelled in the frame of degrading plasticity with viscous hardening, its parameters (related to the probable casting mode) have been identified with direct tensile tests at quasi-static to high loading rates. The computations carried out with varied parameters are described. The results agree well with results of 1/3 scaled prototypes. Thus the steps of development of a scale 1:1 prototype container are considered.
