| Outline of Final Research Achievements |
In this study, we analyzed the characteristics of high intensity radiation generated by pulsed electron beam irradiation. The total radiation energy and the radiation areal density of it was obtained using original measuring methods. Moreover, these results corresponded with its simulation results.
The influence investigation of the electric motor under the supposed environment of damaged reactor which is water vapor and radiation was performed. On the enameled wire which using the electric motor, the surrounding humidity affects for occurring the partial discharge between a pair of wires. The occurrence of the partial discharge was found to be unaffected by the low dose rate of X-ray radiation. We confirmed that the high intensity of radiation has a possibility for affecting the partial discharge occurrence on motor windings.
