Research on Methodology for CPR1000 NPP Fire Functional Analysis

Fire common mode analysis is the safety conformity analysis of fire protection design of nuclear power plants.It is also an important guarantee for the safety of the nuclear power plant.Fire functional analysis is the most important step in the fire common mode analysis,and the basis of defining the fire common modes.This paper elaborates the methodology of the fire functional analysis based on the engineering practice,and then sorts the analysis methods for different equipments,giving the examples and explanations.This methodology has been applied in several projects effectively.
