摘要

摘要结晶硅钛酸盐(CST)离子交换器目前用于从汉福德储罐废物的水相中去除铯(137Cs),为废物处理和固定化厂(WTP)的玻璃化做准备。CST是一种不可洗脱的无机离子交换器,其目标是在柱流出物达到废物接受标准之前保持≥1000的去污因子。为了降低离子交换处理产生的成本,已经对废物处理进行了系统优化。在通过离子交换柱处理之前降低罐废上清液的钠摩尔浓度表明,它可以显著减少所用柱的数量,同时保持必要的钠产量。该工艺的优化可以显著节省成本,并最终减少废物产生。

Optimization of Cesium Ion Exchange Performance with Hanford Tank Waste Feed Dilution
ABSTRACT Crystalline silicotitanate (CST) ion exchanger is currently used to remove cesium (137Cs) from the aqueous phase of Hanford tank wastes in preparation for vitrification at the Waste Treatment and Immobilization Plant (WTP). The CST is a non-elutable inorganic ion exchanger targeted to maintain a decontamination factor of ≥1,000 prior to the column effluent reaching a waste acceptance criterion. In an effort to reduce costs generated by ion exchange processing, system optimization of the waste treatment has been conducted. Decreasing the tank waste supernate sodium molarity prior to processing through the ion exchange columns showed that it can significantly reduce the number of columns used while maintaining the necessary sodium throughput. Optimization of this process can result in significant cost savings and ultimately result in less waste production.
