A theoretical investigation was performed on the passive residual heat removal system (PRHRs) of China Experimental Fast Reactor (CEFR). The system contained two air heat exchangers, two independent heat exchangers and several pipes. By means of JTOPMERET code developed by GSE, the thermodynamic model of the system had been built. Based on the model, transient characteristics of the PRHRs have been discussed in detail. Through the calculation analysis, it is then indicated that the capacity of removing residual heat was affected by some factors. The faster speed of air in the air heat exchanger, the higher temperature and the larger heat transfer area of the air heat exchanger are favorable to the PRHRs. At the same time, the calculated parameters variation trends are reasonable according to the Experimental data from CEFR.
