摘要: 高温气冷堆的余热排出系统为非能动式系统，是一回路舱室冷却系统的组成部分之一。本文建立了10 MW高温气冷实验堆（HTR-10）余热排出系统在反应堆舱室内结构的三维模型，模拟HTR-10运行过程中余热排出系统的工作状况。在HTR-10上进行余热排出系统试验，获得了HTR-10在最高热功率为3 MW条件下余热排出系统的相关数据。将试验数据与模拟结果进行比对，结果表明：模拟结果与试验数据存在偏差。通过分析，提出从模型设计、工况适应性两方面对模型进行优化。Abstract: The residual heat removal system (RHRS) of high temperature gas-cooled reactor plays a passive cooling role and it is one of the components of primary cavity cooling system. A three-dimensional model of the RHRS of the 10 MW High Temperature Gas-cooled Reactor (HTR-10) was built to simulate the working situation of the RHRS. The RHRS experiment on HTR-10 was conducted and the working data of the system were obtained under 3 MW maximum thermal power. The simulation results were compared with the experiment data and deviations were found. Two possible methods which are improving the model design and the model adaptability on different RHRS working conditions are proposed to refine the model.
