Abstract: In this paper, structure, operation mechanism, and inherence security of CFBR-Ⅱ reactor were introduced, possible accident/event type were enumerated too. By using Probability Safety Analysis （PSA） method, event probability of excess pulse fission yield were obtained, and the importance analysis of bottom-events were performed, so as to give enough evidence for preventing accidents of pulse reactor and optimizing design of advanced pulse reactor.
