Proper management of neutron irradiation damage on structural materials is important to ensure the Lealth of long-life fast breeder reactor (FBR) plants. Therefore, the effective index f or irradiation amage or the combination of those should be developed. In this study, the effects of dose, helium, nd the ratio of helium to dose on tensile and creep properties of FBR gra de type 316 stainless steel were investigated in the assumed irradiation damage range of FBR structural materials, that is, up to bout 1...

In a ship's engine room, engineers are surrounded by various noises emitted from the diesel engine, generator, pumps, and other auxiliary machines. During inspections and activities in such environments, workers strive to listen for extraordinary noises issuing from machines and instruments, which might signal a need for maintenance work. I f that practice functions well, proper noise perception helps them perform maintenance work and achieve early detection of abnormalities that would otherwise contribut...

Ultrasonic testing techniques by using the three-dimensional (3D) phased array was investigated. The 3D phased array allows a target region to be scanned volumetrically with focused beams transmitted from a matrix array probe. This leads to an increase in inspection speed and easy-to-u nderstand inspection results displayed as 3D rendered images. This paper focuses mainly on synthesizing techniques of 3D scanned data obtained a t multiple positions when moving the probe. The technique is effective to figu...

In Hamaoka Power Station, thinning management of piping system is considering earthquake In Hamaoka Power Station, thinning management of piping system is considering earthq uake resistance. Current management method is too conservative due to assumption that has large range thinning by liquid droplet impingement erosion (LDI). Therefore, we are developing reasonable earthquake safety evaluation method suited for locally-thinning caused by LDI. To understand the influence on earthquake resistance by the lo...

For seismic safety of piping system with local thinning surface by liquid droplet impingement erosion (LDI), hybrid tests?? were conducted to the piping with locally-thinned elbow. I n this presentation, determination method of the thinning shape on the elbow is developed.To determine the thinning shape by LDI, droplet behavior at the elbow is calculated in vario us flow and piping size conditions, and collision point and velocity for each droplet is evaluated. Then, the relationship between collision cond...
