Simulasi Pelelehan Freeze Plug Termodifikasi pada Molten Salt Reactor Menggunakan Metode Moving Particle Semi-implicit

In the Molten Salt Reactor, freeze plug is one of components that plays an important role when a reactor accident occurs. designing plug, selection constituent material based on ability to spread heat. Therefore, studies are needed provide information regarding design. The modified melting process has been simulated using Moving Particle Semi-Implicit method. This study aims observe behavior phenomena and see effect conductivity value process. alloys used around frozen salts with different thermal Hastelloy-N, Heynes-242, ODS Alloy (MA754). simulation results show time required for salt melt in Heynes-242 variations , (MA754) 12.3 seconds each; 12.7 seconds; 24.3 seconds. obtained explain plugs metal have highest require shorter reach point. shows greater value, easier it heat alloy hits salt.
