Abstract: The European methodology for qualification of non-destructive testing is a well-established approach adopted by nuclear utilities in many European countries. According to this methodology, qualification is based on a combination of technical justification and practical trials. The methodology is qualitative in nature, and it does not give explicit guidance on how the evidence from the technical justification and results from trials should be weighted. A Bayesian model for the quantification process was presented in a previous paper, proposing a way to combine the ¿soft¿ evidence contained in a technical justification with the ¿hard¿ evidence obtained from practical trials. This paper describes the results of a pilot study in which such Bayesian model was applied to three realistic Qualification Dossiers by experienced NDT qualification specialists.
