| 内容記述 | The JT-60U is being upgraded to a full-superconducting tokamak referred as the JT-60 Super Advanced (JT-60SA) as one of the JA-EU broader approach projects. The JT60SA project will use the superconducting magnets to confine the plasma to achieve the plasma current with 100 second-class flat top. The helium refrigerator provides 4 K, 50 K, and 80 K for the superconducting magnets, the HTS current leads, and the thermal shields, respectively. The refrigerator consists of compressors, refrigeration cold box, auxiliary cold box and gaseous helium vessel with a total equivalent cooling power of about 9 kW at 4 K. One of the features of the JT-60SA refrigerator is handling of the pulse heat load by utilizing a 7m3 liquid helium bath equipped in the auxiliary cold box. The helium bath absorbs the pulse heat by consuming the liquid helium. Subsequently after the pulse, the refrigerator starts liquefying the helium to recover the liquid level to the original for the next pulse. The JT-60SA helium refrigerator is manufactured and started on-site installation in Naka Fusion institute by the main contractor Air Liquid Advanced Technology in September 2015. The commissioning started in September 2015 and has been finished in October 2016. In the commissioning followings are tested; automatic cool-down and warm-up, automatic purification, the total cooling capacity, stable operation in the short stand-by(STS) mode, stable operation in the baking(BAK) mode test, quench sequence, regeneration sequence of the diverter cryopanel, operation to cope with dynamic pulse heat loads, etc. In the commissioning, the refrigerator also needs to perform automatic transition between several defined states, such as STS mode and BAK mode. Details of the commissioning will be reported in the conference. |
