To detect instrument failures in the nuclear power plant, a failure detection and isolation (FDI) method based on the Kalman filter is developed. As soon as the residual (difference between an estimated value and its measurement) exceeds the predetermined bound, the Kalman filter indicates the possibility of failures. Various simulations were performed to verify and validate the FDI logic in detecting steam generator pressurizer instrument failures. It is proved that the FDI technique can detect not only a single failure but also simultaneous common-mode and sequential multiple failures of several direct redundancies. Also it can correctly estimate the physical states in real time and the remaining time may be used for control with signal validation.
