A molten salt fast reactor does not have control rods due to inherent safety characteristics. The reactor is in a two-phase flow condition due to He bubbles injected by FP removal. Various transients were analyzed with a neutronics and thermal-hydraulics coupling model using the RELAP5-3D code and FLUENT code inplemented a neutronics model with UDF, under the condition that the safety protection system is bypassed. The transients are UTOP, USBO, ULOFF, and ULOHS. Daily load-following characteristics were also analyzed.
