Distribution of Fission Products in Irradiated Vibrationally Compacted Oxide Fuel

To substantiate the safety of temporary storage and shipment, development of a technology and optimization of conditions for reprocessing irradiated nuclear fuel, it necessary to follow carefully, during materials science investigations, the distribution of diverse fission products in the fuel, the local concentration and chemical state of the fission products, and the influence of the fission products on the change in the state of the fuel components and claddings. In the present paper, the results of an investigation by electron microprobe analysis and scanning electron microscopy of the distribution of fission products in vibrationally compacted fuel after irradiation in fast reactors are presented.[PUBLICATION ABSTRACT]
