Conclusions
A study was made, using the optical microscopy and x-ray diffraction techniques, of the reactions of uranium oxysulfide with boron, silicon, lanthanum, and yttrium in the temperature range 1000–1700°C. Boron and silicon cannot be employed as reducing agents in the synthesis of uranium monosulfide from uranium oxysulfide. It was established that in the operation of a reactor UOS present in sulfide fuel is a harmful impurity because it reacts with lanthanides forming in the course of fission.
