某铀浓缩设施试运行期间辐射防护效果评价

Evaluation on radiation protection in a uranium enrichment facility during trial operation

阐述了某铀浓缩设施四期工程的辐射防护分区、密封屏障设计、气流方向组织以及相应的管理措施。对试运行期间的监测数据进行了分析评价,结果显示:四期工程各项辐射监测指标,包括厂房空气和气载流出物、工作场所表面污染和γ辐射剂量率、工作人员剂量、工作人员尿铀和尿氟水平等远低于国家标准或控制限值要求,防护措施是有效的。

The radiation protection measures including partition,containment,flow organization and relevant managements on the fourth phase project of a uranium enrichment facility are described. The monitoring results including gaseous effluents,surface contamination,worker dose,uranium and fluoride levels in the urine samples of the workers were far lower than national standards and related control limits,demonstrating that the protection measures taken in the facility were effective.
