Abstrakt: In the steam generator of a sodium-cooled fast reactor, heat transfer occurs from the primary sodium flow side at high temperature to the secondary water flow side at low temperature. Preventing the interaction between sodium and water in the heat exchanger is important to avoid a reactive explosion. To do so, the concept of the copper bonded steam generator, which consists of heat-exchanger modules with cross-flow-type arrangement, was recently proposed. In this cross-type arrangement, the sodium flow should be as uniform as possible throughout the horizontal channels in terms of the heat transfer efficiency between the sodium and water sides. This study aims to design a perforated plate leading to uniform sodium flow distribution throughout the 66×33 channels. The geometrical design and location of the perforated plate are optimized using numerical simulation. The designed plate improves the flow distribution uniformity at a slight cost of pressure loss.
