Abstract

The main results of the investigations on the development of spherical particles fuel for fuel elements of HTGR are described. Typical characteristics of UO2 spherical particles (size, shape, density, microstructure etc.) and PyC and SiC protective layers (thickness, density, fission product release etc.) are presented. Sol-gel technique and slip casting are used for spheroidization. Deposition of protective layers is carried out in the fluidized bed apparatus
