Abstract: This paper discusses a development of the quantitative method to evaluate the reliability for the maintenance plan with respect to the risk impact both for Core Damage Frequency and Plant Trip Frequency. The quantitative approach includes the considerations for the effect of the Condition Based Maintenance (CBM) changing in addition to the Time Based Maintenance (TBM), and the reliability for the maintenance plan is evaluated using the actual plant-specific maintenance information collected ...

This paper discusses an improvement of the quantitative method to evaluate the reliability for the maintenance plan with respect to the risk impact both for CDF (Core Damage Frequency) and Plant Trip Frequency. The quantitative approach includes the considerations for the effect of the Condition Based Maintenance (CBM) changing in addition to the Time Based Maintenance (TBM), and the reliability for the maintenance plan is evaluated using component failure rate which is presumed from experimental maintena...

Under the influence of the F1 accident, there is a growing threat to nuclear security. Among the nuclear security threat, current sensing technique is not effective to sabotage by an insider. In this research, for the purpose of detection of dangerous behavior, dealing with the time-series data. The analysis of the data using PCA(Principal Component Analysis) and SBM(Similarity Based Modeling), was determined for several types of motion....

Convolution neural network Feature extraction Nuclear Security Principal Component Analysis Time-series data analysis
Sabotage by malicious insider is one of significant and serious threats for nuclear security of nuclear power plants. It is difficult, however, to distinguish abnormal behaviors from normal works such as their daily maintenance activities. In this study, a technique was proposed to subdivide the abnormal behavior due to sabotage by image analysis and then to detect and identify the abnormal behavior in real time. ...

Adaptive Algorithm Flow Accelerated Corrosion Measurement Errors Modeling Optimization Pipe Thinning Probability Distribution Risk-based Maintenance
In this study, we make a new proposal for the maintenance plan to optimize the total cost, which includes the cost of inspection and replacement, and the damage of the accident. It treats the probability distribution of the initial value and degradation rate of the perfo rmance of equipments. We apply it to the pipe thinning phenomenon in PWR secondary systems....
