摘要
介绍了ACP100发生选址假想事故后,对非居住区边界剂量环境影响的评估方法。基于RG 1.183建立了ACP100选址假想事故后释放到环境的源项计算模型,并结合厂址的气象条件采用PAVA N程序得到非居住区边界剂量,研究了裂变产物释放方式、照射时间、自然去除、厂址气象条件和源项对非居住区边界剂量的影响。结果表明:上述因素对剂量均有较大的影响,确定ACP100非居住区的边界应考虑这些因素。
The environmental impact assessment method for exclusion area boundary dose after ACP100 postulated siting accident is introduced.Based on RG 1.183,the source term calculation model of ACP100 site release into the environment after postulated siting accident was estab-lished.Combined with the meteorological conditions of the plant site,the exclusion area boundary dose was obtained by PAV AN code.The effects of fission product release mode,irradiation time,natural removal,site meteorological conditions and source term on exclusion area boundary dose were studied.The results show that the above factors have great influence on the dose,and these factors should be considered when determining the boundary of ACP100 exclusion area.
