An Original Method for Detection of a Known Anomaly: Application to the Detection of Sudden Coolant Blockage

Résumé

Ensuring the safe operation of critical systems is of the highest importance, particularly when the consequences of a malfunction can be catastrophic. The present paper focuses on developing a reliable and rapid detection method for a critical event in nuclear power plants: the total and instantaneous blockage of coolant flow. Our approach involves modelling the temperature of fuel rod assemblies, taking into account past temperature readings to improve accuracy. By distinguishing between normal and abnormal temperature patterns, we can identify potential blockages early on. The proposed model and associated statistical test are versatile and can be applied to various nuclear reactors and other anomaly detection scenarios. Our results, based on real-world temperature data from the Superphénix power station, demonstrate the accuracy of the proposed model and the relevance of the detection procedure.
