根据美、日能源开发合作协定,由美国能源局与日本原子能研究所合作建造的大型核聚变反应堆,最近已取得两项重大成果。日本原子能研究所与三菱电机(株)合作研制成功了大电流超导线圈,超导材料为铌-锡合金,线圈外径1.6m,内径1.0m,线圈电流17kA,产生磁感应强度7T,暂态过渡时间仅1s。与目前的直流超导线圈相比,能力高出1000倍以上。跃居世界首位。该超导线圈是核聚变反应堆的关键部件之
According to the agreement on cooperation in energy development between the United States and Japan, two major achievements have been achieved recently in large-scale nuclear fusion reactors constructed by the U.S. Department of Energy in cooperation with the Japan Atomic Energy Research Institute. Japan Institute of Atomic Energy and Mitsubishi Electric Co., Ltd. successfully developed a large current superconducting coil, the superconducting material is niobium-tin alloy, the coil diameter 1.6m, an inner diameter of 1.0m, the coil current of 17kA, resulting in a magnetic flux density of 7T, the transient The transition time is only 1s. Compared with the current DC superconducting coil, the ability to more than 1000 times. Leading the world. The superconducting coil is a key component of nuclear fusion reactors
