摘要
An object of the invention is to provide a system for assisting operation at the time of a plant accident, which, even if a device malfunctions at the time of the plant accident, can determine normality of a sensor without being influenced by the malfunction. A system for assisting operation at the time of a plant accident, includes: a phenomenon identification apparatus for identifying a state of a plant; a plant behavior analysis apparatus for predicting progress of a process state after a phenomenon occurs by using at least a phenomenon identification result as an initial condition of plant behavior analysis; and a sensor normality determination apparatus for determining normality of a sensor by comparing a result of prediction of the progress of the process state which is output from the plant behavior analysis apparatus with a sensor signal.
