Localization of Cesium Iodide Vapor on Ceramic Block–Cell Contact Elements in a Nitrogen Environment
摘要
Abstract
The efficiency of separate collection of cesium oxide and molecular iodine, formed during the decomposition of cesium iodide in the process of high-temperature chemisorption on ceramic highly porous block–cell contact elements in a nitrogen environment is studied. The dynamic sorption capacity of the contact elements with an applied aluminosilicate sorption-active layer and with an active layer of silver nitrate for cesium and iodine, respectively, is determined. The developed contact elements are recommended for use in a local gas-cleaning system of the pyrochemical stage of processing of irradiated nuclear fuel from fast neutron reactors.
