     Based on the hourly precipitation data of 2 years on the Fujian Huian and Daya bay nuclear power plant sites,the two parameters "precipitation time fraction" and "distribution ratio of precipitation intensity" of the washout factor model are estimated. Through analysis, the following values of "precipitation time fraction" and "distribution ratio of precipitation intensity" are:FW1= 1.0, FW2=0.91,FW3=0.35,FW4=0.28;

An atmospheric dispersion test on the site of a coastal nuclear power plant located in the east part of China from April, 1995 to April, 1996 is described. The main content is as follows: observation hourly of wind and temperature on the 4 heights of tower of 100 m for 1 year; observation and analysis of surface wind field, sea and land breeze and internal boundary layer; measuring of turbulence and diffusion parameters; wind tunnel simulation experiment and so on. Besed on above field test, a new model is developed...

An atmospheric dispersion test on the site of a coastal nuclear power plant located in the east part of China from April, 1995 to April, 1996 is described. The main content is as follows: observation hourly of wind and temperature on the 4 heights of tower of 100 m for 1 year; observation and analysis of surface wind field, sea and land breeze and internal boundary layer; measuring of turbulence and diffusion parameters; wind tunnel simulation experiment and so on. Besed on above field test, a new model is developed for estimating the annual mean atmospheric dispersion factor for a coastal site of nuclear power plant in which not only the difference between on-shore and off-shore but also the comprehensive effect of following factors are considered: mixed layer and internal boundary layers, mixing release and variation of diffusion parameters due to the distance from coast and so on. A set of deterministic and probabilistic model for estimating the accident washout factor is developed and established. The effect of internal boundary layer on dose and the contribution to dose from the washout deposition pathway are discussed.

描述了1995年4月至1996年4月在我国东部沿海某待建核电厂址进行的为期一年的大气弥散试验。主要实验包括百米气象铁塔四个高度整年风、温逐时观测;地面风场、海陆风及内边界层的观测与分析;湍流与扩散参数测量;风洞模拟实验等。在现场实验基础上尝试提出了计算滨海核电厂址年均大气扩散因子的新模型,此模型既考虑了向岸流与离岸流的区别,又考虑了混合层与内边界层、混合释放与扩散参数随陆距变化等诸因素的综合影响。此外又提出了一套估算事故冲洗因子的确定论模式与概率论模式。讨论了事故工况下,内边界层对事故剂量的影响及冲洗沉积剂量的贡献。

A model to estimate the accident probabilistic dispersion factor in which the effect of internal boundary layer is considered and a set of deterministic and probabilistic models to estimate the accident washout factor are set up based on the models of accident dispersion factor given by current guides. The accident probabilistic dispersion factor, the deterministic washout factor for different time interval after accident release, the accident probabilistic washout factor and the dose corresponding to various pathway are estimated based on the measured meteorological data on the site of a coastal nuclear power plant to be built in the east part of China. The result shows that: the value of accident probabilistic dispersion factor given by the proposed model are 5.9 times of those given by the common model; for the dose obtained during 0 to 8 h after accident release, the external exposure dose from washout deposition given by deterministic model is about 5.50 times of those from dry deposition; the ratio between external exposure dose from washout and dry deposition given by conservative probabilistic model with and without considering the effect from internal boundary layer is 9.56 and 56.7 respectively; for the realistic probabilistic model the value of above ratio is 1.93 and 11.4.

参照当前国内外导则给出的估算事故扩散因子的模式,推荐了一套考虑内边界层影响的估算核电站事故概率扩散因子的模式,并尝试提出了一套估算事故冲洗因子的确定论模式与概率论模式,根据我国东部某待建滨海厂址的实测气象资料,分别估算了事故概率扩散因子、事故后各时段的冲洗因子(确定论模式)、事故概率冲洗因子以及相应的各途径剂量。计算表明,①该模式估算的事故概率大气扩散因子是常用模式估算的5.9倍,②对事故后0~8h的剂量言,确定论给出的冲洗沉积外照射剂量是相应的干沉积外照射剂量的5.50倍,保守概率论给出的上述比值为9.56倍(考虑内边界层影响)和56.7倍(不考虑内边界层影响),现实概率论给出的比值为1.93倍(考虑内边界层)和11.4倍(不考虑内边界层影响)。

A set of deterministic and probabilistic models to estimate the accident washout factor are set up based on the models of accident dispersion factor given by current guides. The deterministic washout factor for different time interval after accident release, the accident probabilistic washout factor and the dose corresponding to deposition pathway are estimated based on the measured meteorological data on the site of a coastal nuclear power plant to be built in the east part of China. The result shows that: the external exposure dose from washout deposition given by deterministic model is about 55% and 21% of those from dry deposition and effective dose respectively during 0 to 8 h after accident release, the ratios of external exposure dose from washout to dry deposition and effective dose in the same time interval given by probabilistic model is 5.73 times and 2.29 times respectively. Therefore, the contribution from external exposure dose of washout deposition should be considered for a coastal site of nuclear power plant. (

本文参照当前国内外常用导则给出的估算事故扩散因子的模式 ,提出了一套估算事故冲洗因子的确定论模式与概率论模式 ,并根据我国东部某待建滨海核电厂址的实测气象资料 ,分别估算了事故后各时段 (0~ 8h、8~ 2 4 h、1~ 4 d和 4~ 30 d)的冲洗因子 (确定论模式 )和事故概率冲洗因子以及相应的沉积外照射剂量。结果表明 ,对事故后 0~ 8h时段而言 ,由确定论模式给出的冲洗沉积外照射有效剂量分别为相应的干沉积外照射有效剂量和总有效剂量 (未包括冲洗沉积 )的 55%和 2 2 % ;而由概率论模式给出的上述比值分别为 5.7和 2 .3倍。由此可见 ,对该滨海核电厂址应该考虑冲洗沉积外照射剂量的贡献。
