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