1. IntroductionThe conductor which is used for thermonuclear fusion reactors must guarantee high current density,excellent transient stability and mechanical stabilityof the magnet structure. The application of CICChas provided these advantages for the design alldconstruction of superconducting magnets, Experimental results of the stability margin of CICC madeby ITER show that the stability margin is largelydependent on operating mass flow. The numericalsimulation was performed with the s… 相似文献

分流温度和温度裕度是管内电缆导体(CICC)稳定运行的关键因素,为应对10T以上的磁场冲击,国际热核聚变反应堆ITER装置上的CS和TF等已采用铌三锡(Nb3Sn)导体,但缺乏应变效应对分流温度和温度裕度分布影响的研究。本文根据在SULTAN对TF样品分流温度和温度裕度的测量数据,首先在无应变下,对由分流温度和温度裕度的改善使得TFCN导体的稳定性得到提高进行分析。然后用周期载荷模拟应变,在600周期和1000周期时,分析CICC分流温度和温度裕度的恶化情况。最后由假设条件,推理并获得分流温度随周期载荷变化的双对数分布模型,该模型能很好描述TFCN导体样品中由周期载荷导致的弯曲应变所产生的性能降级情况。 相似文献

1. IntroductionA program to design and fabricate a tokamakphysics experimental device of HT-7U using superconducting coils has been undertaken by the institute of Plasma Physics, the Chinese Academy of Sciences .The aim of HT-7U is to develop a scientificbasis for a low--cost, clean and continuously operating TOkamak fusion reator. The HT-7U magnet system consists of 16 magnets in the toroidal field (TF)system and 6 pairs of magnets in the poloidal field(PF) system located symmetricall… 相似文献

The neutron shielding component of ITER （International Thermonuclear Experimental Reactor） vacuum vessel is a kind of structure resembling a wall in appearance. A FE （finite element） model is set up by using ANSYS code in terms of its structural features. Static analysis, thermal expansion analysis and dynamic analysis are performed. The static results show that the stress and displacement distribution are allowable, but the high stress appears in the junction between the upper and lower parts. The modal analysis indicates that the biggest deformation exists in the port area. Through modal superposition, the single-point response has been found with the lower rank frequency of the acceleration seismic response spectrum. But the deformation and the stress values are within the permissible limit. The analysis results would benefit the work in the next step and provide some reference for the implementation of the engineering plan in the future. 相似文献
