Abstrakt:

The Molten Salt Fast Reactor (MSFR), a prominent Generation IV reactor design, offers improved safety by eliminating graphite as a moderator and incorporating a passive safety system. Understanding the fuel salt relocation mechanism is crucial in ensuring the reactor’s safety and performance. This study presents a particle-based approach using the Semi-Implicit Moving Particle (MPS) method, which accurately represents fluid as particles carrying essential physical properties. We validate the MPS method as an alternative tool for investigating fuel salt relocation in the MSFR, comparing its results with the well-established δ-SPH method for verification. The simulations encompass scenarios with and without obstacles, involving water-PEO fluids known for their distinct densities and propensity to induce splashing phenomena. The obstacles used are made in several size variations, such as semicircular, rectangular, and triangular obstacles. The excellent alignment of MPS method results with δ-SPH method outcomes confirms its effectiveness in predicting freeze plug melting and fuel salt relocation in the MSFR, providing valuable insights into the passive safety mechanisms. This research contributes to enhancing the safety and efficiency of advanced molten salt reactor designs. Where it can be concluded that the simulation results of the MPS method are almost the same as the simulation results of the δ-SPH method.
