Description
Comprehensive Research Facility for Fusion Technology (CRAFT) was one of the Chinese big science and technology facility. The objectives were to explore and master fusion DEMO level key technologies for next magnetic confinement fusion. In order to test the performance of superconducting magnet, a large-scale helium refrigeration system was proposed and under construction. In this paper, the specification of the helium refrigeration system has been analysed with the capacity of 6.0kW@4.5K +20g/s@50K +15kW@80K for a supercritical helium distribution system and a 250W@1.8K cooling loop with cold compressors. Process flow of the helium refrigeration system has been analysed concerning the different customers and various operation modes. The plant layout of the helium refrigeration system has been designed, including the compressor skid, oil removal skid and cold box. The process and present status of the helium refrigeration system would also be introduced.
