本文系统地调研和分析了国内乏燃料后处理厂核材料管制现状,国外商业乏燃料后处理厂核材料衡算与控制措施的实施经验和采用的关键技术,包括典型商业乏燃料后处理厂物料平衡区和实物盘存关键测量点的设置、核材料衡算与控制措施的总体设计要求、近实时衡算的概念等。根据调研结果和分析,针对我国核材料管制的现状,提出了我国在商业乏燃料后处理厂核材料管制技术准备工作的几点初步建议。

International experience and key technology enlightenment of nuclear material accounting and control in spent fuel reprocessing plant

This paper investigates and analyses the situation of nuclear material control in spent fuel reprocessing plants in China, the key technology and experience of accounting and control measures for nuclear materials in commercial spent fuel reprocessing plants abroad, including the setting of material balance area and key measurement points for inventory in typical commercial spent fuel reprocessing plants, the overall design requirements and reality of accounting and control measures for nuclear materials. The concept of real-time accounting, etc. Based on the investigation results and analysis, and in view of the current situation of nuclear material control in China, some preliminary suggestions for the preparation of nuclear material control technology in commercial spent fuel reprocessing plants in China are put forward.
