In this paper, operating characteristics of the safety system of Chinese Supercritical Water-cooled Reactor (CSR1000) is described. Selecting CSR1000 as the focus of research, and it’s active and passive safety systems are analyzed in turn. A comparison is given between these two types of safety systems. Henceforth, the features of the safety control systems of CSR1000 are obtained. The results show that for the active systems, the control speed of the pressure control system is the fastest and that of the power control system is the slowest. It is observed that the active control system exhibits simple harmonic oscillation. On the other hand, the control feature of passive control system is stable. In addition, coupling the safety systems can ensure the safety of CSR1000 in the event of a loss of flow accident (LOFA).
