Research on Reliability Analysis Method Based on Dynamic Fault Tree

Due to the development of digital technology, digital I&C systems have replaced analog I&C systems and become the mainstream I&C systems for nuclear power plants and marine nuclear power plants. However, there is still a lack of effective and recognized analysis methods for the reliability analysis of digital I&C systems. Based on the commonly used dynamic fault tree analysis method for dynamic system reliability analysis, this paper uses Markov transition matrix to achieve quantitative analysis. Reliability analysis of the digital I&C system, through the improved dynamic fault tree analysis method, provides an effective analysis method for the reliability analysis of the digital I&C system.
