关于贫化铀容器露天存放的安全分析

贫化铀是铀浓缩的副产品,随着核能行业的发展,贫化铀的存储量逐年增加。通过对贫化铀的现有存量、年新增量的模拟推算,对从目前贫化铀存放面临的问题,如容器露天存放仅有一道放射性包容的屏障、贮存需要很多容器、自然环境对容器的腐蚀等对贫化铀容器的露天存储现状进行归纳总结,从流出物排放限值、核事故等级、最大假象事故等方面对贫化铀容器露天存放存在的安全隐患进行分析,进而从核安全监管角度对贫化铀的存放提出意见和建议。

Safety Analysis of Depleted Uranium Containers for Open Storage

Depleted uranium is a byproduct of uranium enrichment.With the development of nuclear energy industry,depleted uranium storage increases year by year.Through the simulation calculation of depleted uranium’s existing stock and annual new increment,this paper summarizes the current situation of depleted uranium’s open-air storage,such as only one radioactive containment barrier for depleted uranium’s openair storage,the need for storage of many containers,and the corrosion of containers by natural environment.This paper analyzes the hidden danger of depleted uranium container in the open air storage from the emission limit,nuclear accident level,maximum false accident and so on,and then puts forward some opinions and rational utilization from the perspective of nuclear safety supervision.
