核电厂严重事故下安全壳通风导致放射性后果的快速评价

提出一种严重事故下安全壳通风导致放射性后果的快速评价方法。通过预先计算通风后安全壳的释放份额和1%初始堆芯总量释入安全壳时的公众个人终身剂量，以及通过事故下安全壳的辐射监测仪表间接得到堆芯向安全壳的释放份额，能够快速评价厂外不同距离处公众的个人终身剂量，它可为严重事故的管理和厂外应急策略的实施提供强有力的支持。

Quick Evaluation of Radiological Consequences for Containment Venting in Severe Accident of Nuclear Power Plant

The quick evaluation method of radiological consequences for containment venting in severe accident was described. Fist of all, the release fraction to environment with containment venting was calculated. Simultaneously, individual lifetime dose to a member of the public at 1% initial core inventory release to containment should be calculated. Then, the core release fraction to containment according to accident radiation instruments in containment was obtained. Finally, individual lifetime dose to a member of the public for different distances outside NPP can be evaluated quickly. It is useful for severe accident management and implementation of emergency countermeasure.
