As a nuclear engineer, risk assessment and management is very important. I wanted to highlight on one of the risk analysis tools used for risk management for nuclear power plants. When I worked at a nuclear power plant, I used Bayesian updating to predict if a system would fail in the plant or not. We would try to turn on the system and every time we tried to turn it on and it either didn’t turn on or stalled, we would count that as a fail. We used this raw data to predict when a system would fail so that we could take it out before it failed. I think that it is a very reliable and practical way to assess risk and ensure people are safe.
