双流体反应堆（DFR）是柏林Fuer Festkoerper-Kernphysicalk研究所在第四代熔盐堆和液态金属冷堆（钠冷快堆和铅冷快堆）概念基础上开发的熔盐快堆。在该概念中，燃料选择为熔融氯化物盐，冷却剂为液态铅。本文建立了反应堆物理分析模型，并总结了作者在零流速条件下使用 U-Pu 混合物默认燃料盐的稳态反应堆物理行为的初步计算和迄今为止取得的结果。它们包括临界计算、中子能谱、空间通量分布、反应速率和功率分布、核素重要性和温度系数。文章的结论评估了 DFR 概念的反应堆物理行为，并对概念本身以及未来的研究给出了评论。本文根据第一作者（X. Wang）博士论文的部分内容修改。
The dual fluid reactor (DFR) is a molten salt fast reactor developed by the Institut fuer Festkoerper‐Kernphysik (Berlin) on the basis of the Gen‐IV molten salt reactor and liquid metal–cooled reactor (sodium‐cooled fast reactor and lead‐cooled fast reactor) concepts. In the concept, the fuel is selected with the molten chloride salt and the coolant is the liquid lead. The article establishes the model for the reactor physics analysis and summarizes the preliminary performed calculations and the achieved results so far by the author on the steady‐state reactor physics behavior with the default fuel salt of U‐Pu mixture under zero‐flow‐velocity conditions. They include criticality calculation, neutron spectrum, spatial flux distribution, reaction rates and power distribution, nuclide importance, and temperature coefficient. The conclusion of the article evaluates the reactor physics behavior of the DFR concept and gives comments on the concept itself as well as on the future researches. The article is modified from a part of the PhD thesis of the first author (X. Wang).
