快中子临界装置堆外物体坠落事故规模计算

摘要

根据弱中子源点火理论推导了反应堆意外超瞬发临界事故的裂变产额估算公式，分析了堆外物体意外坠落在快中子临界装置表面的事故规模。对防止快中子临界装置发生超瞬发临界事故提出了对策建议。%The formula of level of fission yield in case of super-prompt critical accident were gave based the the-ory of neutron sponsoring a persistent fission chain of a weak source .The level of fission yield in case of object fall-ing to the surface of fast neutron critical experiment facility was analyzed .The countermeasure advices to prevent the super-prompt critical accident of fast neutron critical experiment facility were proposed .
