A Review of Molten Salt Reactor Multi-Physics Coupling Models and Development Prospects

Molten salt reactors (MSRs) are one type of GEN-IV advanced that adopt melt mixtures heavy metal elements and molten as both fuel coolant. The liquid allows MSRs to perform online refueling, reprocessing, helium bubbling. utilization, safety, economics can be enhanced, while some new physical mechanisms phenomena emerge simultaneously, which would significantly complicate the numerical simulation MSRs. dual roles in core lead a tighter coupling since released fission energy will absorbed immediately by itself then transferred primary heat exchanger. modeling multi-physics is regarded important aspect MSR study, attracting growing attention worldwide. Up now, great efforts have been made development models over past 60 years, especially after 2000, when was selected for reactors. In this paper, status model extensively reviewed light N-TH (neutronics thermal hydraulics), N-TH-BN (neutronics, hydraulics, burnup) N-TH-BN-G burnup, graphite deformation). problems, challenges, trends outlined provide basis future models.
