AbstractThe results of 5-year operation of the experimental industrial plant for hydrogen isotope separation using combined electrolysis and catalytic exchange (CECE) process are presented. The plant is used for large-scale studies of CECE process and for reprocessing tritiated heavy water wastes. The main parts of the plant are a 100-mm diameter exchange column of 6.9 m overall height, alkaline electrolytic cells and catalytic burners. The separation performance of the column was determined. The computer code makes it possible to carry out the calculation over a wide range of conditions and to forecast a concentration profile within the column when the values of flow rates are changed. The experience gained during the plant operation shows a high efficiency of isotope separation by CECE process and allows regarding CECE process as a considerable promise for the industrial use, in particular, for water purification from tritium.
本文介绍了采用组合电解和催化交换（CECE）工艺的氢同位素分离实验工业装置运行5年的结果。该装置用于CECE工艺的大规模研究以及含氚重水废物的再处理。装置的主要部件包括直径为100毫米、总高度为6.9米的交换柱、碱性电解槽和催化燃烧器。测定了交换柱的分离性能。所开发的计算机程序能够在广泛的条件下进行计算，并在流量值改变时预测柱内的浓度分布。装置运行经验表明，CECE工艺具有较高的同位素分离效率，可视为在工业上具有相当应用前景的工艺，特别是用于从水中去除氚。
