Local system for purifying process gases from volatile compounds of cesium and iodine at high-temperature stages of spent nuclear fuel reprocessing

Abstract

The paper presents a local system for purifying gas flows from volatile compounds of cesium and iodine released during high-temperature operations of spent nuclear fuel reprocessing. The system consists of two universal cartridge gas purification units. The performed study include data on the efficiency of capturing cesium oxide and molecular iodine by ceramic highly porous block-cell contact elements with an aluminosilicate and silver nitrate active layers, respectively. Recommendations for further conditioning of spent cartridges are provided.
