On-line channel instability localisation with fuzzy rule-based systems

A fuzzy rule-based system is proposed for on-line channel instability localisation within a nuclear reactor, employing a limited number of detector responses. The signals used for constructing the fuzzy rule-based system are obtained from a rough simulation of the reactor and correspond to a restricted number of channel instability locations. Tests with novel channels of instability, which are obtained from a more detailed simulation and cover an extensive number of channel instability locations, demonstrate the potential of the proposed methodology to accurately, robustly and efficiently localise channel instability.
