Abstract :
Brief introduction of cryogenic helium and hydrogen circulation system of Chinese Spallation Neutron Source (CSNS) is given. According to heat load change of pulsed-proton-beam injection, the temperature and pressure of supercritical hydrogen are calculated. Based on the calculation results, profiles of temperature and pressure with the change of heat load are given. Accordingly, controlling optimization strategy of hydrogen circulation is preliminarily concluded. The results may provide guidelines for design and operation of other under-constructed SNS pressure controlling system.
