The article addresses computational research on the decision of multi-criterial problem of how to optimize sodium heat exchanger. A heat exchanger under consideration is one of the elements of sodium loop (SL) being designed to provide sodium circulation in the IGR reactor experiments with fast reactor core elements. The research covered mathematical calculation to select geometry for heat exchanger and identify required coolant flow rate. In ANSYS FLUENT software system, heat exchanger 3D model was developed using chosen geometry and stationary thermal calculation was conducted. Distribution of heat exchanger temperature field with the coolants was received in 3D calculation. Computational research resulted in receiving best range of heat-exchanger parameters, creating 3D computational model and providing distribution of temperature field for optimized model.
