Condition-based maintenance(CBM) is maintenance performed on the basis of the condition of the equipment. The transition to CBM being considered, it is necessary to make appropriate decision, such as judgment of normality or abnormality. The threshold approach has generally been used for the judgment, but it provides ambiguous decisions due to individual variability of the equipment. Diagnosis using Data Analysis is a promising method to detect variations of the condition of rotating machinery. In this meth...

Cosmic-ray muon is high energy leptons generated in the earth’s atmospheres as results of cosmic-ray proton/electron bombardment. Muon scattering method has been developed for nuclear security applications using its highly penetrative feature and sensitivity for high Z-materials. This study introduced the measurement of small nuclear reactor which consists of UO2 fuels and simulation study of container scanning system by muon scattering method. These results showed effectiveness of muon scattering metho...

An electrical isolation planning system is now under development to improve the efficiency of operating and maintaining nuclear power plant. The system automates electrical isolation planning, and evaluates the influence of the isolation plan. It also equips an algorithm that automatically adds information such as circuit connection and device attribution to the original paper-drawing. A demonstration of automatic isolation planning was conducted that used actual plant drawings. The system successfully repr...
