ITER PF2导体短样的电流分流温度测试与GANDALF模拟

Current Sharing Temperature Test and Simulation with GANDALF Code for ITER PF2 Conductor Sample

摘要: 近期ITER PF2线圈所用的CICC导体短样在SULTAN实验室完成了一系列测试。根据试验结果, CICC导体短样表现出良好的电流分流温度性能, 在45 kA, 4 T 和5 K的PF2线圈典型运行条件下, CICC导体短样的电流分流温度试验结果为6.71 K, 对应的温度裕度为1.71 K。为了与试验结果进行比较, 本文使用一维GANDALF程序对PF2 导体进行模拟分析, 其分析结果与测试数据吻合。

Abstract: Recently the ITER PF2 coils CICC conductor sample is tested in SULTAN facility. A series of tests are performed. According to the test result, the CICC conductor sample shows stable performance about the current sharing temperature. At the typical PF2 coil operating condition of 45 kA, 4 T and 5 K, the test result of conductor current sharing temperature is 6.71 K, with a temperature margin of 1.71 K. To compare with the result, a thermal-hydraulic analysis of PF2 conductor has been simulated with 1-D model GANDALF code. The test results are consistent with the simulation.
