Abstract


The liquid-fueled molten salt reactor uses liquid fuel, and its dynamic characteristics are different from the traditional solid fuel reactor. Dynamic modeling and simulation play a key role in the design phase of the innovative reactor system. Based on Modelica language, a Modelica model named TMSRLib (Thorium-based Molten Salt Reactor Library) for dynamic modeling and simulation of liquid-fueled molten salt reactor system is developed using Dymola platform. In order to verify the validity of the developed dynamic simulation model library, two system models of the MSRE (molten salt reactor experiment) with core represented by single region and nine regions are built based on the TMSRLib Modelica library, respectively. Then the two system models of the MSRE are validated by using experimental benchmarks of MSRE. The results show that the numerical results are in good agreement with MSRE experimental results, and verifies the applicability and correctness of each component model in TMSRLib.
