本幻灯片演示的目的是: detn U和Ra去除效率； SAC SBA的detn树脂容量； 找出SBA树脂的最佳用量； 分层床还是混床？； 定义U型床的最小SBA床深度 移动和 比较NaCl和KCl作为再生剂。这篇演讲概述了用离子交换法去除铀的信息 交换: 使用MR SBA w/wo SAC； 树脂选择不重要； BV run w纯阴离子:300000 BV mo； 因此₄^2-将缩短运行长度； pH值在6-9范围内不临界； 典型循环操作 30000-50000 BV（60-00天）， 以20磅/立方英尺（4/）的饱和氯化钠再生，以及 即使再生不完全，泄漏也很低。该演示文稿解释了在钠软化过程中镭如何在树脂中移动，以及镭泄漏的分析方法和解决方案。包括表格、数字。

The objectives of this slide presentation were to: detn U and Ra removal efficiencies; detn resin capacities for SAC SBA; find optimum % of SBA resin; stratified or mixed bed?; define minimum SBA bed depth for U removal; and, compare NaCl and KCl as regenerants. The presentation outlines information on uranium removal by ion exchange: use MR SBA w/wo SAC; resin selection not critical; BV run w pure anion: 300,000 BV mo; SO₄^2- will shorten run length; pH not critical in 6-9 range; typical cyclic operation 30,000--50,000 BV (60- 00 days), regen with sat'd. NaCl at 20 lbs/ft3 (4/ ), and low leakage even w incomplete regen. The presentation provides an explanation of how radium moves through the resin during sodium softening, along with analysis methods and solutions to Ra leakage. Includes tables, figures.
