Condition Based Maintenance Magnetron X-band Linac X-ray
We are developing portable non-destructive testing (NDT) X-ray source with X-band linac and low power magnetron. Now, we start the experiment of electron acceleration and X-ray generation using by 950 keV X-band linac NDT system. The 950 keV X-band linac X-ray generator is under development for corrosion wastage of tubes and condition bas ed maintenance of impeller pumps. However, about 1 MeV X-ray source can be only used for thin tubes of about 20 mm thickness. Therefore, we start to design about 4 MeV X-...

CBM Linac Nondestructive X-Band X-ray
We have been developed 9.4 GHz X-Band linac and 250kW magnetron for X-ray nondestructive tes ting system for Condition Based Maintenance (CBM). Our linac's energy is 950 keV, which fits to Japanese regulation to take them to outside of radiation controlled area. This small port able linac enables to diagnosis the moving facility, such as bearing in Nuclear Power Plants....

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...
