A lot of radiation damage occurs in nuclear fuel materials in the course of their technological application. It arises from a wide range of damage sources: fission, fast neutrons, alpha-particles and heavy recoil atoms from the alpha-decay, beta- and gamma-radiation. The full spectrum of damage production is considered, from predominantly nuclear to predominantly electronic stopping. Much has been learned from careful examination of reactor irradiated materials, as well as from extensive parametric studies employing controlled ion implantation and using wide ranges of elements, doses, ion energies and implantation temperatures. The present article focusses on ceramic nuclear materials for fission reactors, mainly the nuclear fuels UO(2), UC and UN. The available knowledge of the various aspects (type, extent, affected physical properties, recovery temperatures etc.) is summarised, and the importance of radiation damage phenomena in the technological application of the above nuclear fuel materials is explained.
