In this paper the problem of expert judgement (EJ) in probabilistic safety assessment is recognised as a true knowledge problem. A critical analysis of traditional EJ methodologies leads to highlight some common weak points of theirs. The suggestion is made to reformulate the expert opinion issue in a Knowledge Engineering setting in order to reach a sound basis for comparison, integration and justification of expert knowledge and relevant uncertainty.
The proposed innovative approach is described in its goals, and requirements for its development are detailed.
