钠冷快堆混合钠火程序开发

钠管道泄漏继而发生钠的燃烧为钠冷快堆特有的事故。在喷雾钠火模型和池式钠火模型基础上，将钠喷雾燃烧和池式燃烧进行了耦合，并针对钠冷快堆钠工艺间的结构特点，最终开发了混合钠火计算程序COMSFIRE。使用该程序计算了FAUNA喷雾钠火试验和CADARACHE池式钠火试验，并与试验结果和部分程序计算结果进行了对比。同时设计了混合燃烧算例，并使用该程序与CONTAIN-LMR程序进行了对比。通过计算结果的对比和分析，初步验证了程序的正确性。

Development of Sodium-cooled Fast Reactor Sodium Combined Fire Code

Sodium fire caused by sodium pipe leakage is the specific accident for sodium-cooled fast reactor. Based on the sodium spray fire model and sodium pool fire model, sodium spray fire and sodium pool fire were coupled together. A sodium combined fire code COMSFIRE was finally developed based on the structure characteristic of sodium technology room in sodium-cooled fast reactor. FAUNA sodium spray fire experiment and CADARACHE sodium pool fire experiment were calculated with the developed COMSFIRE code, the results of which were compared with the experiments results and some other code results. A combined fire case was designed, and the results were compared with CONTAIN-LMR code. The correctness of the COMSFIRE code was primarily proved through the comparison and analysis.
