| Summary: | The freeze plug will melt in an emergency situation at the Molten Salt Fast Reactor (MSFR), which can then be relocated to the draining tank for cooling. Research has been carried out on freeze plug melting and drainage systems of MSFR using a particle-based method, namely the Moving Particle Semi-implicit (MPS) in which the fluid is represented by particles and each particle carries physical information such as position, velocity, pressure, and temperature. The
freeze plug melting simulation was compared using designs with and without additional metal. The simulation results showed that the design with copper-type additional metal reached the frozen salt melting point faster. Then determine the copper size by monitoring the copper thickness from 1.5 mm to 3.5 mm in 0.5 mm increments. To understand the fundamentals of fluid interactions in the process of vertically relocating molten fuel to the same fluid using fluids with various kinematic viscosities, that is water, ethylene glycol, and engine oil, it must have been discovered that engine oil is the fluid with the highest kinematic viscosity had a lower flow velocity and reached stable flow position faster. Then, to describe the fluid flow of liquid fuel, run a simulation using liquid fuel, specifically LiF-Th4. |
