Effects of radiation on nuclear materials
All nuclear materials experience radiation damage in the course of their technological application. This can be due to the slowing down of high energy, heavy ions (i.e. fission products), or to neutrons or radioactive decay. In addition, chemical effects and electronic excitation/ionisation have to be taken into account. For nuclear ceramics, radiation effects are particularly complex, as the compounds have different sublattices with largely varying atomic numbers. In this paper, emphasis is placed on nuclear fuels and on matrices for the solidification of radioactive waste. Important phenomena include radiation-induced or -enhanced diffusion and re-solution of fission rare gas atoms from gas bubbles. Finally, the effects of self-radiation damage in waste glasses and ceramics such as SYNROC are considered.
