摘要
根据船用反应堆的实际运行经验和设计特点,以船用压水堆作为研究对象建立船用堆模型。假定在反应堆运行终期堆芯骤然发生事故,利用FCSC源项分析程序计算事故源项,并通过QAD-CGA点核积分屏蔽计算程序计算堆舱各参考点的剂量率,分析得出了船用反应堆舱室在不同运行工况和事故工况下的剂量分布特点,可以为船舰内人员的剂量评价提供参考。
According to the actual operation experience of marine reactor and the characteristics of the design, a marine PWR model is established. The source term is calculated with the FCSC analysis program and the dose rate of each reference point is computed by using QAD-CGA shielding calculation program based on a point kernel code in the accident condition. The characteristics of dose distribution are analyzed at different operational and accident conditions in marine reactor cabin, which provides reference for personnel dose evaluation.
