Abstract

The paper describes the expert panel methodology developed for helping risk-informed decision making, and its application to evaluate the preliminary results in the STUK's RI-ISI (Risk-Informed In-Service Inspection) pilot study. The aim of an expert panel is to achieve a balanced utilisation of information and expertise from several disciplines in decision-making including probabilistic safety assessment as one decision criterion. In the RI-ISI application, the expert panel approach was used to combine the deterministic information on degradation mechanisms and probabilistic information on pipe break consequences. The expert panel served both as a critical review of the preliminary results and as a decision support for the final definition of risk categories of piping.
