The preliminary study of natural convection simulation for the SAMOP test facility cooling process

The present numerical simulation deals with the cooling of a subcritical assembly for Molybdenum-99 production (SAMOP) test facility by natural convection of water. The natural convection takes place at vertically cylindrical annuli contained in an open tank with the different constant heat fluxes a...

description	The present numerical simulation deals with the cooling of a subcritical assembly for Molybdenum-99 production (SAMOP) test facility by natural convection of water. The natural convection takes place at vertically cylindrical annuli contained in an open tank with the different constant heat fluxes applied at each annulus wall. The main purpose of this study is to evaluate the capability of natural convection of water to remove the fission heat. The numerical simulation was performed in the steady state condition using ANSYS FLUENT 17.2. The 2D axisymmetric model was analyzed as the preliminary study. The numerical result showed that the maximum temperatures of coolant and fuel tube wall were 307.4 K and 307.5 K, respectively. The average temperature of water in the SAMOP tank was 303.8 K. It concludes that the natural convection of water designed for cooling the SAMOP test facility has fulfilled the safety aspect of thermal hydraulics.
