摘要: CAP1400为我国自行研发的装机容量为140万kW的先进非能动三代核电机组。本文以高斯烟羽模型为基础,介绍了我国自行设计的CAP1400核电站正常运行工况下气载排出物的弥散模式。针对实际情况,计算中对模型进行了相关修正,如有效源高、干湿沉积、放射性衰减等,结合示范电厂石岛湾厂址的气象数据,采用C-AIRDOS程序对气载放射性核素的大气弥散因子、年均浓度分布和部分核素的地面沉积浓度进行了模拟计算。为了解CAP1400示范核电厂运行后对周边地区的辐射环境影响提供了参考信息。

关键词: CAP1400, 核电厂, 大气弥散因子, 空气浓度, 地面沉积率

Abstract: China Advanced Passive Nuclear Power Plant with installed capacity reaching to 1400 MW (CAP1400) is independently designed as the China's state-of-the-art 3rd generation nuclear power brand. The concentration of typical radionuclides dispersed from CAP1400 under normal operations were calculated with modified Gaussian model, considering effective height of the source, dry deposition, wet deposition, radioactive decay etc. The average annual ground level concentration of radionuclides distribution from CAP1400 was obtained by C-AIRDOS computer code on the site of Shidao Bay. The atmospheric dispersion factor and ground deposition rate were also investigated. These calculated results will provide valuable information for understanding the effect on radiation environment due to the radionuclides dispersed from CAP1400 Nuclear Power Plant under normal operations.

Key words: CAP1400, Nuclear Power Plant, atmospheric dispersion factor, concentration of radionuclide, ground deposition rate
