Description
The future nuclear plants like ITER, DEMO or PROTO are interested by the problems of dust creation and resuspension. Radioactive dust, if resuspended by accidents in the vacuum vessel, can be dangerous because of its toxicity and capacity to explode under certain conditions. The authors have been working since 2006 on dust resuspension problems through the STARDUST facility before and the STARDUST-U facility now. During the experimental campaign they have widely related the thermos-fluidodynamic conditions inside the facility during the accidents reproductions with the dust resuspension. In this work the author have performed scanning electron microscopy (SEM) and X-Ray diffraction (XRD) analyses of the dust (used for the experiments) after different temperature and pressure cycles. The results of these analysis will be compared with the previous data and critically presented by the authors.
