核事故后果评价系统的进展与比较

Comparison and Advance of Consequences Assessment System for Nuclear Accident

对国内外若干主要的核事故后果评价系统 ,如美国的 ARAC、日本的 SPEEDI、欧共体的 RODOS、中国的CRODOS等的性能进行了概述与比较。对核事故后果评价中的主要组成部分 ,如大气扩散模型、动态食物链模型、防护措施、干预水平及计算防护措施有效性中所需的屏蔽因子。

The quality of several main consequences assessment systems for nuclear accident such as ARAC(USA)?SPEEDI(Japan)?RODOS(CE)and CRODOS(China) are summarized and compared. The review of several main components of Accident Consequences Assessment (ACA) system such as atmospheric dispersion model?dynamic food chain model?protective measure and shielding factor and occupancy factor used in calculating effectivness of protective measure is described.
