Axial Groove Type Rotor double probe technique Steam Turbine Tip echo technique Ultrasonic Testing
Refracted angle for UT of axial groove type rotor is limited with the distance of the axial direction from the sensor installation surface. High intensity detection technique changes with the refracted angle, the change may require a combination of multiple inspection techniques. For this reason, detectable distance of a double probe technique and a tip echo technique are examined. In the distance more than 35mm, refracted angle become more than 35 degrees where refracted intensity is high and the defe...

Deformation Nondestructive Evaluation Potentiostatic Etching Stainless Steel TwinPlastic Strain
To ensure integrity of structures and components in nuclear power plants, the demand has been increased for establishing nondestructive method for detection of pre-existing plastic strain. In this study, potentiostatic etch ing method is applied to detect and quantitatively measure plastic strain imposed to austenitic stainless steels by tensile straining. After potentiostatic etching (1N HNO3, -600mVsce, 20min), twin lines and slip lines appe ar as etched lines on the surface of specimen because of the pr...

To ensure integrity of the structure such as nuclear power plant, the demand has been increased for establishing nondestructive method for detection of pre-existing plastic st rain. In this study, potentiostatic etching method is applied to detect and measure plastic strain imposed to austenitic stainless steel by tensile straining. After potensiost atic etching (1N HNO3, -600mVsce, 20min), the twin band appears as etched line on the surface of specimens. The etched twin band is observed by optical microsc...

The structural integrity of equipment and piping systems to a fault displacement depends on the damage state of a reactor building. When there is no damage in a reactor building, the supporting function of equipment and piping systems is maintained. In this case, FEM analysis can estimate the allowable state of the entire system of the important safety equipment. In this part, an example of the analysis evaluation for the equipment and piping systems, which are important for safety, in the case of loading a...
