摘要/Abstract

摘要： 田湾3、4号机组采用俄方设计制造的VVER-1000型反应堆,其正常运行气液态流出物排放源项是检验核电厂设计是否满足国家相关环境标准的重要指标,是辐射防护最优化设计的重要内容之一。以我国压水堆核电厂源项框架体系为基础,通过分析田湾核电站相关工艺系统流程,选取合适的工艺回路部件数学模型,采用电厂设计以及实际运行经验参数,分别计算了设计与现实排放源项,并与俄方计算结果进行对比,说明采用新源项框架体系下气液态放射性流出物的变化情况。

关键词: VVER-1000, 气液态流出物, 源项

Abstract: VVER-1000 units was designed and manipulated by Russian in Tianwan nuclear power station, of which radioactivity with gaseous and liquid discharges on normal operations is one of the most important index that can testify the design of NPP satisfy the relative national environmental standard’s requirements, and one of the most important content of radiation protection optimization. This paper is based on the national pressurized water reactor NPP source term framework, by analyzing Tianwan NPP relative system process flow, established mathematical models of each equipment in different circuit system when the reactor is under normal operations, adopted design and operational parameters, and calculated realistic and conservative source term respectively. The results is compared with Russian’s, and presents the changes after the new source term framework being adopted.

Key words: VVER-1000, gaseous and liquid effluents, source term
