[en] The safety characteristics of the key design features of the KALIMER conceptual design are investigated using the system analysis code, SSC-K. The accident initiator considered is a loss of flow with failure of scram (ULOF). Various analyses of multiple faults such as loss of heat sink, transient overpower, or failure of GEMs with the ULOF are performed. The purpose of this analysis is to assess the effectiveness of the inherent safety features adopted in the preliminary KALIMER design for the ULOF events. It has been shown through the present analyses that the KALIMER design has inherent safety characteristics and is capable of accommodating the various types of ULOF. The self-regulation of power without scram is mainly attributed to the inherent and passive reactivity feedbacks in conjunction with the GEMs. Function of the GEM during the ULOF appears to be highly effective.
