Evaluation of Uncertainties in Relation to Severe Accidents and
Level-2 Probabilistic Safety Analysis

Workshop Proceedings
Aix-en-Provence, France
7-9 November 2005

Uncertainty in relation to several severe accident phenomena plays a major role in probabilistic safety analyses involving beyond-design-basis accident scenarios for nuclear power plants. The technical papers presented herein will be valuable for nuclear safety analysts, nuclear power plant designers and R&D managers, especially with regard to unresolved severe accident issues or issues where risk uncertainty is high.

Session I: Introduction

Presentation: Ming L. ANG, NNC Ltd, United Kingdom. Treatment of Uncertainties in Level 2 PSAs and Severe Accident Analysis - An Overview and Some Thoughts Regarding Future Challenges.
