Abstract In operating of nuclear power plants, it is required not only to preserve and improve the reliability and safety, but also to introduce more efficient and lower cost maintenance strategy simultaneously, due to t he power trading deregulation in recent years. In addition, as the number of experienced operators / maintenance personnel decreases, comprehensive implementation of objective and transparent information provision syste m on plant operation and maintenance (O&M) being compliant with the la...

Abstract The NDT method using electromagnetic waves has the possibility to detect widely and quickly inner surface crack existin g in large pipes. The purpose of this study is to demonstrate validity of the method to detect the thin crack introduced by pla sma discharge fabrication. Through this study, it has been shown that both reflected and transmitted waves carry a lot of inform ation on existence of the crack. Experimental results indicate that there exists attractive possibility in this new NDT metho...

This paper studies the resolution of defects by a Lorenz type of Electro-Magnetic Acoustic Transducer on the basis of simulation of ultrasonic imag ing. Transmission and reception processes and propagation of induced ultrasonic wave are formulated and numerically solved by FEM and FDM. It is sh own that the smallest defect with the size of the special division of FDM can be detected from the ultrasonic image using ALOK method. It is also shown from similarity rules that the resolution of defects becomes 1...

Abstract Maintenance is an activity to keep the functions of systems, structures and components against aging phenomena. Maintenance has so far been carried out based on experience of the experts mainly engaged in the plant. However in order to make a suitable maintenance program, it is necessary to predict the future based on past knowledge and past research data. Then, it is necessary to regard m aintenance as sciences and to systematize maintenance, that is, maintenology needs to be constructed. As the ...
