Post irradiation experiments on physical, thermal and microstructural properties of neutron-irradiated ceramics

not registered

This is a summary report on the post-irradiation experiments of physical, thermal and microstructural properties of neutron-irradiated various ceramics, which are expected to be applied to the in-core materials of an Advanced Fast Breeder Reactor in near future. Four candidate ceramics, Al $_{2}$ O $_{3}$ , AlN, SiC and Si $_{3}$ N $_{4}$ were fast neutron irradiated up to 4.210 $^{26}$ n/m $^{2}$ in the CMIR-4 rig in the JOYO reactor. The following observations were performed and the obtained results are mentioned. (1)Microstructural observation by means of transmission electron microscopy (2)Measurement of swelling (3)Measurement of thermal diffusivity by a laser-flush method (4)Recovery of swelling by isochronal annealing (5)Recovery of thermal diffusivity by isochronal annealing
