| Research Abstract |
The preexisting models for describing the process of radiation damage due to high-energy fission fragments in UO_2 is reexamined by experimentally simulating the radiation damage process by means of a high-energy ion accelerator. The experimental basis for the simulation is constructed, fundamental radiation damage data are obtained for ion-irradiated UO_2, method for the prediction of radiation damage especially in high-energy regime is proposed, and the formation mechanism for rim-structure formed in high burn-up fuels is examined. The limitation of preexisting models is clarified, and the process which should be taken into account for the modification of the models is proposed.
