ＩＴＥＲ‐ＣＳモデル・コイルとＣＳインサート・コイルの実験結果 ＩＴＥＲ‐ＣＳインサート・コイルのクエンチ特性

Abstract

The Central Solenoid (CS) insert coil and the CS model coil (CSMC) have been developed in the Engineering Design Activity (EDA) for the International Thermonuclear Experimental Reactor (ITER). They are wound with the ITER CS conductor. The CSMC is composed of 18 layer windings, whose most important object is to generate 13-T magnetic field at 46-kA current, so the coil does not have instrumentation in winding. The CS insert coil is a single layer coil and was tested under a field generated by CSMC. This coil was fabricated to study its performance when wound with the ITER CS conductor, so the coil has much instrumentation in winding. Both coils are very stable and achieved their rated condition without quench. To study the quench characteristics, we made artificial quenches by heating the coils. Many data about quench behavior of CS insert coil were obtained from the experiment. The results of quench property, propagation velocity, pressure rise, and temperature rise are reported and compared with the calculation results.
