【摘要】 本文应用在福建惠安核电厂址和江苏田湾核电厂址所作的SF6 野外示踪试验结果验证了在核电厂环境影响评价中广泛应用的高斯烟羽模式的有效性。惠安核电厂址于 2 0 0 2年 7月进行了 1 5次SF6示踪试验 ,其中释放高度为 70m的 5次、3 0m的 6次、1 0m的 4次 ,释放时大气稳定度B C、D、E类各为5、9、1次。田湾核电厂址于 1 997年 8月共进行了 1 0次SF6 示踪试验 ,释放高度皆为 90m ,天气类型皆为D类。对示踪试验结果分析表明 ,各采样点SF6 地面浓度的模式计算值和示踪试验实测值在其比值为0 .2 5至 4.0范围内基本相符更多还原

【Abstract】 Based on the data of SF 6 tracer tests at the Fujian Huian and Jiangsu Tianwan nuclear power plant′s site, the validation of the Gaussian plume model that is commonly used in environmental impact assessment of NPP is examined. Fifteen sets of SF 6 tracer tests were done in Fujian Huian NPP in which the height of release is 70 m(5 sets),30 m(6 sets),10 m(4 sets),respectively, and the atmospheric stability was B,C,D,E respectively,. Ten sets of SF 6 tracer tests were done in Tianwan NPP in which the height of release was totally 90 m and the atmospheric stability was totally D. The analysis shows that the calculation values are in basically agreement with measuring values within the region of ratio of 0.25 to 4.0. (更多还原
