摘　　要：介绍了聚变堆用Nb3Sn超导磁体管内电缆导体(CICC)的结构型式和参数,以及超导磁体的运行工况,采用一维数学模型Gandalf对超临界氦迫流冷却回路进行压降计算,从理论上确定了较为合理的液氦质量流率。The structure and parameters of the cable-in-conduit conductor (CICC) and the operation condition of the Nb3Sn superconducting magnet used in fusion experimental device in China were introduced. A one-dimensional mathematical model, Gandalf, was used to calculate the pressure drop in CICC under the circulating mode of forced flow cooling which used supercritical helium as coolant, and consequently the relatively reasonable mass flow of liquid helium in theory was obtained.
