简要介绍了中国散裂中子源（CSNS）低温氦氢循环系统。根据脉冲质子束注入热负荷的变化，计算了超临界氢的温度和压力。根据计算结果，给出了温度和压力随热负荷变化的分布。在此基础上，初步总结出了氢气循环的控制优化策略。研究结果可为其他在建SNS压力控制系统的设计和运行提供指导。
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.
