摘　　要：利用流体力学计算软件Airpak对核动力船舶主控室通风系统进行数值模拟,提出通风结构的改进措施。选取主控室内典型的截面,分析放射性气体在截面处的分布情况,通过调节进出风口的位置,合理将气载放射性物质约束在无人员岗位区域;并通过模拟计算说明可通过改进通风方案来改善工作人员的工作环境,减少工作人员的辐射剂量。Nuclear ship master control room has been simulated for the ventilation system by using fluid mechanics calculation software Airpak. The new measure is proposed to improve the ventilation structure. Several typical iso-surfaces are selected to analysis the concentration distribution of airborne radionuclide. The airborne radionuclide is restricted within no staff area by adjusting the inflow and outflow position. The simulation results show that the improved ventilation scheme can improve working environment and reduce staff radiation dosage.
