Condition Based Maintenance X-band Linac X-ray
We are developing X-ray nondestructive testing (NDT) system using with portable X-band linac. This system uses 2.4 GHz X-band linac and 250 kW magnetron. Our system energy is 950 keV for Japanese regulation. Th erefore we can use it on-site using local radiation protection. We measured electron beam and X-ray. We have started X-ray maging test. We will use this system for condition based maintenance of pump-impeller a t nuclear plants. The linac based X-ray source can generate pulsed X-ray. Therefore we ca...

Condition based Maintenance J-PARC Neutron Residual Stress S-N Curve
Condition Based Maintenance (CBM) is very important for safety of nuclear plants. We analyze basic experimental data for quantitative lifetime evaluation of bearings. So far the lifetime is guessed by fitting curves for signal out puts from vibration gauges. However data spread of results is rather large depending on the conditions of equipment, operation and environment. We are performing AE-, vibration- and oil-debris- analyses and trying to understand th e fracture status more directly. Further, we newl...
