海洋条件下非能动余热排出系统运行特性

Operational characteristics of the passive residual heat removal system under marine conditions

  • 摘要: 在海洋条件下,非能动安全系统受船舶运动的影响,将产生随时空动态变化的附加惯性力,进而导致系统的运行特性发生变化。基于自编译系统程序,建立适用于海洋条件下非能动余热排出系统运行特性分析的数学模型,分别对海洋条件下六自由度运动状态的系统运行特性进行了计算分析。研究结果表明:摇摆运动会导致系统运行参数发生周期性的波动,并削弱系统的自然循环能力,其中横摇对系统运行特性的影响最为突出;而在横荡与垂荡工况下,尽管海洋条件引入的附加力会引起系统流量波动,但对系统流量的平均值并不会产生影响。此外,研究还表明,在所分析的运动参数谱的范围内,提出的非能动余热排出系统能正常导出堆芯余热。

     

    Abstract: Passive safety systems will be affected by ship motion and the introduced additional inertial force which varies with the time and space as it operates in marine conditions. To study the transient operational characteristics, a mathematical model of the Passive Residual Heat Removal System (PRHRS) was established and a simulation program developed. Six degrees-of-freedom motion was investigated respectively, and the results show that the natural circulation capacity of PRHRS decreases and flow rate oscillates due to marine conditions, while the rolling motion has the greatest impact. However, the swaying and heaving motion has no effect on the average flow rate of PRHRS though the observed flow rate oscillation. In addition, the results also show that the PRHRS system can start normally and remove the residual heat from the nuclear reactor within the calculated parameter region.
