为完成CAP1400非能动堆芯冷却系统试验验证,设计并建造了1/3高度比例的ACME整体试验台架.针对整体试验中堆芯处的关键热工水力过程进行比例分析,确定堆芯模拟体设计所需满足的相似准则,并在综合考虑加热棒制造工艺参数等因素后,通过不同方案比较确定了ACME堆芯模拟体加热棒参数及整体几何排布方案.为在试验运行过程中有效支撑加热棒,采用了具有梅花孔支撑形式的支撑板,并通过阻力计算确定支撑板流通孔开孔结构尺寸,以匹配台架堆芯阻力设计要求.结果表明:ACME试验台架堆芯模拟体的设计通过了加工制造、组装、阻力测试和试验运行各环节的验证,其设计满足整体试验要求.
In order to complete the CAP1400 passive core cooling system test verification, ACME overall test bench of 1/3 height ratio was designed and constructed.According to the ratio analysis of the key thermal-hydraulic processes in the core of the whole test, The design of the similar criteria to be met, and after comprehensive consideration of the heating rod manufacturing process parameters and other factors, through different programs to determine the ACME core simulation body heating rod parameters and the overall geometric arrangement program in order to effectively support the operation of the test Heating rod, a support plate with plumule hole support was adopted, and the hole size of support hole flow hole was determined through the resistance calculation to match the design requirements of the platform core resistance.The results show that the ACME test bench core simulation body The design has passed the verification of manufacturing, assembly, resistance test and test operation, and the design meets the overall test requirements.
