In-reactor measurements of the spontaneous and long-term change in electrical conductivity of α-alumina were carried out in the JMTR fission reactor. The so-called radiation-induced conductivity, RIC, was observed and evaluated qualitatively as well as quantitatively. A long-term increase in electrical conductivity was observed, which is thought to be due to the so-called radiation-induced electrical degradation, RIED.
