SOM based methods in early fault detection of nuclear industry

Abstract

Abstract. Early fault detection in nuclear industry is studied. Tools have been developed for control room operators and experts in an industrial project. Self-Organizing Map (SOM) method has been used in combination with other methods. Decision support visualizations are introduced. The usability of methods have been tested and verified by constructing prototype systems. The use of SOM method in dynamic systems is discussed. Applications for industrial domain are presented. Data sets from a Finnish nuclear power plant have been analyzed. Promising results in failure management are achieved. 1
