The liquid sodium loop test facility incorporates a sodium pump with two radial outlets, each connected to a heat exchanger (HX) for forced sodium flow. However, due to the non-availability of one heat exchanger during the loop commissioning, it becomes necessary to address the flow imbalance caused in the pump outlet nozzle and its piping system. To achieve a balanced flow distribution between two radial outlets from the pump, an orifice plate called here as a heat exchanger equivalent device is proposed. It interconnects the piping which is not having a heat exchanger to balance the flow and flow-induced nozzle forces from pump outlets. Based on careful evaluation, it is proposed to incorporate an orifice plate with multiple holes as the HX equivalent device. The design of the orifice plate was carried out and the same is analysed through 3D CFD simulations to ensure proper flow distribution and force balance between the outlet nozzles of the sodium pump. The numerical study aims to predict the pressure drop of the newly developed heat exchanger equivalent device. The study also aims to investigate the impact of elbows located upstream and downstream of the equivalent device on the flow distribution in a test facility. This study provides a comprehensive analysis and presents a practical solution using an orifice plate as an HX equivalent device and the impact of elbows on flow distribution in a sodium loop. The findings contribute to successful commissioning of the test facility, even with the limited availability of heat exchanger and the presence of elbows in the piping system nearer to the orifice device.
