Some Aspects of Investigating Fuel Densification during Repeated Thermal Treatment

摘要

Questions of interrelation of reactor compaction of fuel under irradiation and its behavior during the repeated thermal treatment (resintering) are considered. It is shown that testing the fuel via its resintering allow one to monitor its quality, to evaluate the stability of the production process of its obtaining, and to forecast its in-pile behavior via determining the amount of unstable small pores in it. The main statements for selection of parameters of the repeated thermal treatment of the fuel are presented. Formulas for calculation of capacity of the fuel to resinter are presented.
