Conference paper


Whenever an event with potentially or actually catastrophic consequences occurs, it is common practice to review these events to identify important, systemic lessons for the affected industries. However, despite recent pushes to make increasing use of risk information in decision making, the scope of these reviews does not always address one important part of the system, the probabilistic risk assessment (PRA) technology supporting the risk assessment models used to develop this information. This paper looks at a set of noteworthy events with this topic in mind.
