Abstract:

Various operating conditions of the HeCEL-3 helium coolant experimental loop, including steady state and transient state scenarios, have been simulated using large-scale system and safety analysis software APROS. The results not only provide reference values for the equipment parameters and the ranges of the thermal hydraulic parameter, but also give the changes of main parameters during transient operation. These provide a comprehensive reference data for the preliminary design of the loop. Meanwhile, the analysis results also can provide references for the design of cooling system of China fusion engineering test reactor (CFETR) and future nuclear fusion reactor.

摘要：

利用大型系统与安全分析软件APROS 对氦冷实验回路(HeCEL-3)进行了包括稳态和瞬态的工况分析，不仅给出了回路设备参数的选取参考值、回路热工参数的分布，而且给出了回路瞬态运行的主要参数变化，为回路的设计和进一步设备调研提供了数据参考。同时，其分析过程和结果对中国聚变工程实验堆(CFETR)和未来聚变堆冷却回路的设计也有一定的借鉴意义。
