Abstract

The aim of this work is to analyze the effects of the core and loop (external) time constants on the delayed-neutron precursors in fluid-fueled molten salt reactors (MSR). A 0-D mathematical model of neutron precursor concentration and neutron power without feedback effects is used for this analysis. For different time constants, we present the behavior of the precursors concentration, thermal power, and the external reactivity. According to the obtained results, we find that the external reactivity is small for large time constants in the core and in the external loop.
