Fault Tree Analysis of the Marine Reactor Blackout Accident
The reliability of the marine reactor power supply system has an important impact on the safety of nuclear power plants.Referring to the design of a typical marine reactor power supply system,a basic principle of fault tree modeling for marine re-actor power supply system is proposed,the fault tree is established based on the marine reactor blackout accident as the top event.Based on the adjacency matrix of the system,a program of fault tree aided generation and minimum cut set solution is designed.The probability of power failure accident and the importance of each power supply equipment are obtained through qualitative and quanti-tative analysis,and corresponding improvement measures are proposed to provide technical support for the design,use and mainte-nance of the power supply system of the marine reactor.
