Fukushima Daiichi Nuclear Power Plant accident in Japan has dealt a deadly warning for the world on the safety of nuclear power plant operations. A big challenge to maintain the safe operation of nuclear power reactors and plants is to establish monitoring over nuclear power facilities and to realize early warnings of equipment problems. Based on a comparative analysis of current vibration diagnosis techniques and fault diagnosis expert systems, the research adopts technologies in mining of massive datasets and develops an on-line condition monitoring and pre-warning system for nuclear power plant facilities. The system achieves management over the entire nuclear power plant facilities and significantly increases equipment reliability and availability, as well as lowers occurrence of potential risks. The research has great impact on developing on-line condition monitoring and pre-warning system for nuclear power plant facilities.
