The benefits of probabilistic risk assessment
During the past 15 yr, probabilistic risk assessment (PRA) has been used to enable decision makers to prudently choose between alternatives for achieving safety. While the primary benefits of PRA application have been many lessons learned about contributors to nuclear plant risk, there have also been benefits in the form of lessons learned about how to do risk assessments. Examples have to do with data handling, plant and system modeling, capturing the operator's perspective, controlling the scope, technology transfer, and achieving scrutability. There is still much room for improvement in all these and other areas. Still, the progress toward real time and continuous quantitative risk management has been extremely encouraging. The key is to have patience and not expect the process to be automatic.
