| 摘 要： | 本文结合核舰船的设计特点和实际运行经验，分析了核事故时放射性核素由核反应堆舱（以下简称堆舱）向其他舱室的传输途径及在各舱室中的分布，给出了放射性素活度和人员剂量的估算方法，计算了核事故情况下各舱室的辐射水平和人员的受照剂量，后果评价表明，设计基准事故时，各舱室辐射后果较轻，人员剂量没有超过有关标准规定的剂量限值，严重事故时，堆舱邻舱辐射后果严重，人员剂量超过有关标准规定的剂量限值。

| Abstract: | This paper discussed about the spread routes of radioactive nuclides from reactor cabin to other cabins and their distributions in these cabins. Methods and formulas to estimate radioactivities of nuclides and doses received by crews in cabins were established. The radiation consequences of cabins in a nuclear accident was quantified and evaluated. The assessments indicates that the consequences of cabins is light and the doses to the staff will not exceed the dose limits prescribed in standards in a design basis accident,and the consequences of cabins is serious and the doses to the staff will exceed the dose limits prescribed in standards in serious accident. Some suggestions on emergency management and radiation protection were given.$$$$( |
