摘要: 从放射性废物减量化管理原则出发,探讨了重水蒸汽回收系统干燥剂分类进行除氚处理和水泥固化的技术路线,对干燥剂进行除氚处理使其满足清洁解控标准,对无法满足解控标准的干燥剂与含硼浓缩液进行混合固化处理。初步试验结果表明,利用高温加热和微波处理可实现干燥剂的除氚处理;干燥剂与含硼浓缩液混合固化是可行的。

Abstract: Based on the minimization principle of radioactive waste management, two treatment methods ware discussed for disused drying agents from heavy water vapor recovery system, detritiation and mixed solidification. The detritiation solution can be applied when the drying agents are rendered, to be compliance with clearance levels. Otherwise mixed solidification should be used. Preliminary test results show that high temperature heating and microwave treatment are applicable for detritiation; the mixed solidification of drying agents and boroned concentrate is feasible.

Key words: nuclear power plants, disused drying agents, detritiation, mixed solidification, clearance, volume reduction and minimization
