摘要
为研究热管冷却空间堆系统从冷态零功率到满功率的启动特性,以典型热管冷却空间反应堆电源系统SAIRS为对象,开发了热管冷却空间反应堆系统瞬态程序TAPIRS。该程序的模型主要包括中子动力学模型、堆芯传热模型、热管模型、碱金属热电转换装置(AMTEC)能量转换模型和散热板模型。将TAPIRS程序各模块和系统稳态计算结果与参考文献计算值比较分析,验证了本文模型和求解方法的合理性。启动特性研究表明,通过控制控制鼓的转动速率,可实现反应堆从次临界到满功率、热管和AMTEC从固态到正常运行状态的启动过程。热管冷却空间堆依靠核热启动具有可行性,热管最高温度不超过1 250K,满功率参数与相关文献的最大相对误差不超过6%。
To investigate the transient startup characteristics from the cold zero power condition to the full power state of a heat pipe cooled space reactor（HPS）,a calculation code TAPIRS based on the typical heat pipe cooled space reactor SAIRS was developed.The code integrates separately validated point reactor kinetics model,core heat transfer model,heat pipe（HP）model,energy conversion model of alkali metal thermal-toelectric conversion units（AMTEC）and radiator model.By comparing the simulation results of the models and steady state with those in the references,the rationality of the models and the solution method was validated.It is found that by adjusting the control drum＇s rotational speed,the reactor can be started from the subcritical state to the full power state.The heat pipe and the AMTEC can be started from the solid state to the normal operation state.HPS can startup entirely depending on the nuclear power,and the maximum temperature of the heat pipe does not exceed 1 250 Kin the whole startup process.The maximum relative errors of the parameters between the simulation results of this paper and those in the literatures at the full power condition are less than 6%.
