The Joint EC/USNRC project on Uncertainty Analysis of Probabilistic Accident Consequence Codes: Overall Objectives and New Developments in the Use of Expert Judgement

This paper describes the results of an ongoing EC/USNRC joint project on the uncertainty analysis of probabilistic accident consequence codes for nuclear applications. The uncertainty distributions are obtained using a formal expert elicitation procedure based on methods from Delft University of Technology and NUREG-1150 experience in the US.
