摘　　要：系统软件对熔盐堆冷却剂系统的整体模拟、瞬态分析和安全研究起到至关重要的作用。针对化工领域系统仿真软件HYSYS进行二次开发,植入熔盐物性,修改熔盐换热模型,利用软件已有模型(等效回路加热器模型)尝试分析其对熔盐冷却系统仿真的可行性。为验证修改后的软件的可靠性,对中国科学院上海应用物理研究所钍基核能中心硝酸盐熔盐(KNO3-NaNO2-NaNO3 Molten Salt,HTS)实验装置进行了系统仿真模拟,并与实验结果进行了对比。结果显示,扩展后的软件对熔盐冷却系统的分析研究具有较好的适用性。Background： System code is important for the dynamic simulation and safety analysis of the molten salt cooling system. There is no professional system code for molten salt-cooled system yet. The HYSYS code is a process simulation environment designed to serve many processing industries. It has a potential ability for the global simulation of the molten salt cooling system as well as transient and accident safety analysis. Purpose： The aim is to validate the modified HYSYS code for molten salt cooling system application. Methods： Based on the KNOa-NaNO2-NaNO3 molten salt （HTS） experiment device, the thermal-dynamic and transport properties were implemented into the HYSYS code, and a precise and complete model was built for HYSYS code. The model was used to simulate the HTS loop under different conditions. The corresponding experiments were also executed, and then the simulated results were compared with the experimental data to validate the HYSYS code application. Results： The simulated temperature data are in good agreement with the experimental results. Conclusion： The modified HYSYS code is available in simulating molten salt-cooled loop system.
