For a long period of time Probabilistic Safety Assessment (PSA) for Nuclear Power Plants were performed using Fault Tree (FT) and Event Tree (ET) technique. This technique has its pros and cons as any other currently used methodology. After Fukushima Daiichi accident problem with addressing multiple hazards had arrived and many scientists are trying to address it with new approaches for example Bayesian techniques.

One of the most crucial point of a nuclear reactor's safety is behaviour during severe transient and withstand them. This is even more important in case of new concepts of reactors, especially when LWR's (Light Water Reactors) regulations have to be modified to be appropriate for others designs.
