Civa 10 RX module: Preliminary validation in a nuclear context

The French Institute for Radioprotection and Nuclear Safety (IRSN) in partnership with CEA, has started in 2009 a program over several years for the validation of CIVA RX module. The aim of this paper is to present preliminary results of CIVA RX tools validation. The study consists in a cross comparison between experimental and simulation results. These have been carried out on different objects (step wedge, dissimilar metal weld mock up, IQI, notches) with different sources (Co{sup 60} and 450 kV X-ray tube) and radiographic film. Simulation and experimental data are compared in term of optical density, IQI perceptivity and flaws detectability. This study shows a good agreement between experiment and simulation.
