Abstract
Experiments on high-temperature processing of VVER-1000 SNF with a burnout depth of 47 GW day/tU were carried out in order to determine the dependence of the extent of semi-volatile fission product removal on the time of SNF processing in an oxidizing atmosphere for subsequent optimization of technological modes of this process. It was found that, during high-temperature processing at 1200°С for 8 h, more than 30% of Mo, 90% of Cs, and 100% of Ru and Tc are removed.
