There have been many events related to human performance errors in nuclear power plants. Even though human makes mistakes, we have established the K-HPES (Korean Human Performance Enhance system) at our company’s web system to make efforts to reduce the human performance errors in our nuclear power plants. Through this system, we have prevented the similar human errors of other plants doing the follow-up measures such as the inspection and improvement of our facilities, the revision of procedures, and training for employees. In this paper, we introduced the analysis of the K-HPES cases caused by human performance errors in Nuclear Power Plants last year.

Fukusima nuclear power plant accident occurred due to a big earthquake and a tsunami in Japan on March 11 in 2011. Since then, the aftereffect of the accident has hit nuclear power industry stronger than expected. In our country, a lot of measures have been also taken to strengthen the safety of the nuclear power plant. Old nuclear power plants like kori unit 1 and wolsong unit 1 should be performed a stress test, which evaluates the maintainability of plant safety assuming the most severe accident that has no power supply and ultimate heat sink. In this paper, we introduced the stress test results performed for kori unit 1 plant related to the plant operational parts such as organization, personnel, working procedure, man-machine interface, education and training, etc.

There have happened many events related to the OEs (Operating Experiences) including human performance errors in nuclear power plants. And in our company (KHNP), K-HPES (Korean Human Performance Enhance system) have been established to make efforts to prevent the human errors. In this paper, we have introduced the events caused by human performance errors in our Nuclear Power Plants last year.

There have been several transient events like a reactor trip related to the unskilled operations at the touch screen in nuclear power plants lately, and the installations of the touch screens have been increased steadily in our nation’s nuclear power plants widely with reflection of the digital times in recent years. Therefore, it is required that the nuclear power plant’s operators should study the principle for the touch screen and handle it with care. At the end, the prevention program (flash) for the human performance error has been developed in order to cope with these problems. In this paper, we introduced performance requirements, development methods, and utilization of the developed program (flash).

Envelope analysis is most conventionally used for detection of rolling element bearing faults by bandpass filtering the raw signal and then extracting its envelope and then analyzing fault frequency energy by Fourier transform. However, traditional Envelope analysis based algorithm such as high frequency resonance technique and spectral kurtosis has limitation in extracting faulty signal and constructing optimal bandpass-filter. This paper employs empirical mode decomposition(EMD) to decompose signal and sort fault implemented signal and particle swarm optimization(PSO)to optimize bandpass filter. The performance of “EMD+PSO Envelope analysis” was checked under varying fault location and load condition by CWRU data, and varying operating speed and fault size by SNU data. It was shown that suggested algorithm successfully diagnose four commonly occur bearing fault location and also naturally formed distributed fault under different speed and loading condition. It was also shown that suggested algorithm presents much higher performance compare to three previously introduced Envelope analysis algorithm.
