Development Progress of Critical Equipment in the CSNS Cryogenic Hydrogen System

Most of the cryogenic hydrogen apparatuses in the CSNS hydrogen system are non-standard equipment, and will be developed independently. This paper introduces the latest research progress. Manufacturing of the accumulator has been completed in February 2014. A prototype of the hydrogen-helium heat exchanger has been manufactured and tested for sealing. The manufacture of the cryogenic hydrogen heater and the ortho-para hydrogen convertor will be finished soon. These cryogenic devices will be integrated into the hydrogen cold box and the accumulator cold box. The engineering design of the cold boxes was completed, and the vessel of the hydrogen cold box has been manufactured.
