ABSTRACT:
A transient mitigation system and method of operation is provided for a nuclear reactor having a reactor core. A plurality of monitors monitor operation of the reactor. A plurality of independent feedback control systems control respective reactor operations. The transient mitigation system is integrated with the control systems for automatically adjusting a selected one thereof to mitigate abnormal behavior of the monitored operations. A data base contains predetermined membership functions of monitoring and control parameters, each membership function including a plurality of discrete adjacent ranges having respective values. An encoder identifies membership ranges and values for respective singular monitoring parameter values which are evaluated in predetermined fuzzy control rules to select a control parameter and membership range to mitigate the abnormal behavior. A decoder provides a single value mitigating signal for the selected control parameter range to mitigate the abnormal behavior.
