摘　　要：针对非能动堆芯补水系统在海洋条件下的安注运行特性和安全分析的问题,本文建立了流体附加惯性力模型。通过对系统分析程序ARSAC二次开发,获得了能够模拟海洋条件下非能动堆芯补水系统安注过程的计算程序,并开展了初步验证和非能动堆芯补水系统安注特性数值模拟。研究表明:附加惯性力模型及相应的程序节点模型能够预测海洋条件对非能动堆芯补水系统的影响。起伏工况下,非能动堆芯补水系统安注流量呈周期性波动,其振幅受起伏加速度和周期影响;摇摆条件不同,形成的附加惯性力存在显著差异,安注流量的波动特性显著不同;倾斜工况会改变非能动堆芯补水系统冷热两端的高度差,从而影响安注流量。本文可为海洋条件下非能动系统的设计及分析提供参考。Aiming at the problems of safety injection operation characteristics and safety analysis of passive core makeup system(PCMS)under ocean conditions.A calculation program capable of simulating the safety injection process of PCMS in oceanic environments was created and preliminarily validated by extending the system analysis program ARSAC.Numerical simulations under various ocean conditions were conducted.Results reveal that the additional inertia force model and relevant program node model effectively predict the effects of ocean conditions on PCMS performance.Under fluctuating conditions,the safety injection flow rate periodically fluctuates,with its amplitude influenced by the amplitude and period of fluctuation.Different rolling conditions result in significant differences in additional inertial forces formed,leading to distinct fluctuation characteristics of the flow rate.Tilted working conditions alter the height difference between the hot and cold ends of the PCMS,thereby affecting the safety injection flow rate.These findings offer valuable insights for the design and analysis of passive systems operating under oceanic conditions.
