摘　　要：本文对我国大型核电站燃料组件生产线运行8年来的辐射环境影响进行综合分析和评价。结果表明,在正常运行工况下,放射性流出物对厂区周围公众造成的年最大个人有效剂量为7.26×10-4mSv;半径为80 km范围内的集体有效剂量8年来累积为156.4人.mSv,年平均为19.5人.mSv;气载放射性流出物对集体剂量的贡献约占98.5%。This paper describes radiological environmental impact of large-sized nuclear power fuel assemblies manufacturing in China from 1994 to 2001. The results show that the maximum individual effective dose of the public around the site caused by radioactive effluents under normal operation is 7.26 × 10^-4 mSv. The collective effective dose within radius of 80 km from 1994 to 2001 is 156.4 man·mSv and annual average 19.5 man·mSv. The contribution of airborne radioactive effluents to the collective effective dose is about 98.5 % of the total.
