Description

RiskA is a home-developed probabilistic safety assessment software by FDS team. Large numbers of real fault tree models of nuclear power plants are calculated by RiskA and Risk Spectrum. Comparative analysis shows that the fault tree qualitative and quantitative analysis of RiskA is accurate and efficient. On the contrary, Risk Spectrum may be ill-considered and faulty in some cases though it is used by 40% of the world nuclear power plants, as the probability of each MCS is inconsistent with theoretical value which is calculated based on the technology of rank truncation.
