Fault-tree analysis using modular logic models
Nuclear power plants have many features in common. The functions and configuration of safety systems, and the types of components used in the systems are similar for different plants. We developed modular logic models to represent the fundamental fault logic for many commonly occurring nuclear power plant features. We further defined procedures to guide the fault tree analyst through the process of altering and connecting appropriate modular logic models to build detailed fault trees for specific systems. An interactive computer system is used to assemble and alter the modular logic models. This paper discusses the modular logic approach to fault tree analysis and describes the tools currently available to support the approach.
