Abstract
An in-situ experiment investigating the radiation induced electrical d egradation (RIED) effect in polycrystalline alumina is described. A We sgo AL-995 polycrystalline alumina sample has been irradiated with fis sion neutrons to 1.4 displacements per atom (dpa) at 340-365 degrees C with no evidence of RIED. The implications of these and previous resu lts are discussed in terms of their impact on the International Thermo nuclear Experimental Reactor (ITER), with the conclusion that RIED wil l be of no consequence during the basic performance phase of the machi nes operation.
