摘　　要：为实现在厂址环境参数有限的条件下对核设施气载流出物排放所致公众剂量进行保守且快速的评价,本研究基于国际原子能机构(IAEA)安全报告丛书第113号报告所提出的筛选评价策略开发了气载流出物排放所致公众剂量分级筛选评价模型,可实现放射性气载流出物大气排放所致公众剂量由保守到现实的分级筛选评价。研究中进行了“华龙一号”机组气载C-14流出物排放情景的案例研究,并对不同评价模型的结果进行了比较,研究结果表明所开发的筛选评价模型可靠,其可被应用于缺乏评价参数时对各类核设施气载流出物排放的筛选评价,以及监管机构对评价结果的独立审查等领域。To implement a conservative and rapid assessment of public exposure due to airborne effluent discharge from nuclear facilities under the conditions of limited environmental parameters of facility site,this study develops a graded screening assessment model based on the screening assessment strategy proposed in the IAEA Safety Report Series No.113,which can implement a conservative to realistic assessment of public exposure due to airborne effluent discharge to atmosphere.A case study of airborne C-14 effluent release scenarios from Hualong One nuclear reactor was established and the assessment results of different public exposure assessment models were compared.The results of the study demonstrate the robustness of the developed screening assessment model.The model can be used for screening assessment of airborne effluent discharge from different types of nuclear facilities when assessment parameters are not available,and for independent review of assessment results by regulatory agencies.
