【摘要】 描述了于2002年夏季在福建惠安核电厂址进行的SF6示踪试验及其主要结果。共进行了15次SF6示踪试验,其中释放高度为70m的五次,30m的六次,10m的四次。天气类型若按?T-U分类,B,C,D,E类天气分别出现3,2,9,1次,若按?T分类,B,D,E类天气分别出现1,11,3次。每次约取50个样品,最远取样点距释放SF6的铁塔15km左右。基于这次试验给出了适用于该厂址各类天气条件下的扩散参数,最后把试验推荐的扩散参数与P-G曲线,Briggs扩散参数以及以往在该厂址进行的湍流测量与风洞模拟实验推荐的扩散参数进行了比较分析。更多还原

【Abstract】 The SF6 tracer tests and its main results completed in site of Fujian Huian Nuclear Power Plant during summer, 2002, are described. A total of 15 times of SF6 tracer tests were done in the July, in which the time of atmospheric stability B, C, D, E is respectively 3, 2, 9, 1 based on ?T-U method and the time of B, D, E is respectively 1, 11, 3 based on ?T method. About 50 samples were collected in each SF6 tracer tests, the maximum of sample distance from the tower in which the SF6 tracer was released is about 15 km. The values of py , pz , qy , qz in the formula of diffusion parameters is determined. Finally the above diffusion parameters are compared with P-G curve, Briggs diffusion parameters and those obtained from turbulence observation and wind tunnel simulation test done in the past time.更多还原
