摘　　要：蒸发浓缩技术是处理放射性废液常见的、主要方法之一,本文介绍了含硝酸放射性废液蒸发试验台架在验证中出现的二次蒸汽冷凝液酸度超标、废液量大等问题;并对问题产生的原因进行了分析,最后结合现场实际提出了现场的改进措施或者后续的优化建议。The technology of evaporative concentration for high level liquid waste is among the most prevalent and primary approaches to treating radioactive liquid waste.This study is primarily concerned with the challenges pertaining to the excessive acidity of secondary steam condensate,the substantial volume of high tritium liquid waste during the evaporation process.It delves into the underlying causes of these issues and culminated in the proposal of on-site improvement measures or subsequent optimization suggestions based on the specific circumstances.
