摘　　要：本文通过对国内外海流数值预报、放射性物质在海域的输运数值模拟和剂量评估等方法的分析研究,建立了用于核电厂海域放射性后果预测与评价的数值模拟方法,确立了核电厂海域放射性后果预测与评价系统的总体研发方案,为该系统的顺利研发奠定了技术基础。该系统的建立可实现对我国不同核电厂址核事故状态下液态放射性物质在近岸海域的辐射后果的精细模拟,同时也能快速模拟核电厂址海域辐射后果,以满足核事故应急响应工作对时效性和准确性的需求,进而可有效提升我国核事故的应急响应能力。Based on the investigation of ocean current numerical forecast, the numerical simulation of radioactive effluent dispersion in the sea area and radiological dose assessment of domestic and overseas, the research and development plan of numerical simulation software system is established, which will lay the foundation for the system development. In order to meet the timeliness and accuracy of nuclear accident emergency response, the system is designed to finely assess nearshore radiation consequences and quickly estimate radiation consequences in the China sea happened at domestic different nuclear site, and then enhances effectively China＇s nuclear accident emergency response capabilities.
