早期核燃料后处理厂箱体设备退役研究

Decommissioning of cabinet equipment in early nuclear fuel reprocessing plants

早期核燃料后处理厂中箱体设备包括手套箱、工作箱、取样柜等,由于当时认识的局限性以及科学水平的不足,早期后处理厂停产后未开展必要的去污,导致部分箱体设备放射性污染严重。对某早期核燃料后处理厂内的箱体设备进行梳理,根据箱体设备的结构类型及污染特征,分析了箱体设备可选用的去污和拆除方法,论述了箱体设备去污拆除的初步方案。

The cabinet equipments in the early nuclear fuel reprocessing plant includes glove boxes, work boxes, sampling cabinets, etc.. Due to the limitations of understanding at that time and the lack of scientific level, the early reprocessing plant did not carry out the necessary decontamination after the suspension of production, resulting in serious radioactive pollution of some cabinet equipment. This article sorts out the cabinet equipments, analyzes the decontamination and dismantling methods available for the cabinet equipments according to the structural type and pollution characteristics of the cabinet equipments, and discusses the preliminary scheme of decontamination and dismantling of the cabinet equipments.
