The invention relates to the technical field of risk monitoring of
nuclear power plants, and particularly discloses a risk monitoring
model development method for a high-temperature gas cooled reactor
nuclear power plant with two reactors with one
machine, comprising the following steps: S1, analyzing an originating event; s2,
event sequence analysis; s3, analyzing a
system fault tree; s4, component
common cause failure analysis; s5, personnel reliability analysis; s6, quantifying the accident sequence; s7, verifying the model; according to the method, the
significant difference between the fourth-generation high-temperature gas cooled reactor and the second-generation
pressurized water reactor is comprehensively considered, expansion analysis is carried out on a two-reactor one-
machine-carrying mode, a double-reactor average
risk model is established, expansion and conversion of a risk monitoring model are carried out, all power
plant configurations are reflected, the real-time risk of the power
plant can be reflected more truly, and the real-time risk of the power plant is improved. Power plant commissioning
modes, equipment states (operation or shutdown), environmental factors and the like are reflected in real time, key scientific and technical problems of
operation safety management of the high-temperature gas cooled reactor
nuclear power plant are solved, and support is provided for safe, stable and economical operation of the high-temperature gas cooled reactor
nuclear power plant.
