METHOD AND SYSTEM FOR EVALUATING SAFETY STATE OF NUCLEAR POWER PLANT, AND NUCLEAR POWER PLANT DEVICE

摘要

A method and system for evaluating a safety state of a nuclear power plant, and a nuclear power plant device. The method for evaluating a safety state of a nuclear power plant comprises: acquiring operating states of all nuclear power plant safety parameters in a pre-established nuclear power plant safety parameter logical relationship model (S101); according to a pre-set safety evaluation rule and safety levels for the nuclear power plant safety parameters, evaluating the safety levels of the operating states of all the acquired nuclear power plant safety parameters so as to acquire the safety levels of all the nuclear power plant safety parameters (S102); and carrying out logical operation processing on the acquired safety levels of all the nuclear power plant safety parameters according to a safety parameter logical relationship in the established nuclear power plant safety parameter logical relationship model so as to acquire a safety level of the overall safety state of a nuclear power plant (S103). The method improves the convenience, accuracy and reliability of nuclear power plant safety state evaluation, and improves the safety and reliability of a nuclear power plant.
