Abstract
An electrical resistivity of polycrystal α-alumina was measured at about 680 K in a dynamic pumping condition in a fission reactor, JMTR. In a good vacuum, we observed smaller RIC (radiation-induced conductivity) than our previous results. We observed RIED (radiation-induced electrical degradation) -like behavior. The results suggested that RIED would take off faster at a higher ionizing dose rate. In the mean-time, the take-off occurred at about the same displacement damage of about 0.03-0.05 dpa in the range of fast neutron flux of (3.4-15.1) × 1013 n/cm2 s.
