Description
In this paper, binary decision diagram (BDD) algorithm is used for fault tree analysis. The ways of calculating failure probability and minimal cut-set (MCS) for certain fault trees are presented, including conversion from fault tree to BDD structure, obtaining MCS from BDD, MCS storage in terms of zero-suppressed BDD (ZBDD) for space-saving, and calculation of top event unavailability. A program was compiled and validated by calculating a PSA model of certain nuclear power plant both by hand and RiskSpectrum PSA. The comparison results show that the program can qualify and quantify a fault tree of relatively small scale. (authors)
