本文分析了中子辐照环境下的仲氢向正氢转化的现象,结合CSNS低温系统的特点,开展了正仲氢转化反应器的方案设计,并在此基础上重点讨论了现有的正仲氢测量方案的特点.后续将根据项目现场的实际情况,开展正仲氢测量方案的选择和设计工作。正仲氢转化及其组分测量方案的研究,为后续CSNS低温系统的顺利建设提供理论基础。
This paper analyzes the conversion of secondary hydrogen to normal hydrogen in the neutron irradiation environment. Combined with the characteristics of the CSNS cryogenic system, the scheme design of the forward-conversion hydrogen metathesis reactor is carried out. On this basis, the existing positive Secondary hydrogen measurement program features.After follow-up will be based on the actual situation of the project site to carry out the measurement and selection of positive ion hydrogen design work. The study on the conversion of normal parahydrogen and its composition measurement scheme provide the theoretical basis for the smooth construction of the subsequent CSNS cryogenic system.
