90-19/U模拟高放玻璃固化体的浸出特性评价

摘要: 采用动态及静态浸泡法，研究了浸泡温度、流速和浸泡剂对模拟高放玻璃固化体９Ｏ－１９／Ｕ的浸出影响，对固化体的浸出特性进行了评价。实验发现，浸泡温度对浸出的影响十分明显；固化体的浸出随流速的增加而增加。实验结果表明，９Ｏ－１９／Ｕ模拟高放玻璃固化体是一种比较好的玻璃固化体形式。

Abstract: EVALUATION ON LEACH BEHAVIOR OF 90－19／U SIMULATED HLW-GLASS FORMSHENG JIAWEI；LUO SHANGGENG；TANG BAOLONG；ZHOU HUI（China Institute of Atomic Energy，P，O. Box 275（93）,Beijing 102413）ABSTRACT The influences of temnperature， 1eachant and leachant flow rate on the leacbing behavior of90-19／U simulated HLW-glass form are studied using the static and dynamic leaching tests． Theleaching properties are also evaluated． Experimental results show that the influence of temperatureis very significant and the mass losses of HLW-glass form increase with increasing leachant flowrate. It is found that 90-19／U simulated HLW-glass form is a good form of glass formulation. Key words HLW-glass form Static leach Dynamic leach Leach rate
