Stress analysis of IHX Facility in SFR

The intermediate heat exchangers which are located at the boundary of the hot and cold pools (classification of Redan), strongly influence the heat transportation from the primary side to the secondary side through the piping line situated at the internal flow path. Therefore, investigation of IHX is of importance for the design of the SFR concept. The IHX performances were tested in Intermediate Heat Exchanger test Loop for PGSFR Safety (IHELPS) experimental facility of KAERI. However, instead of sodium, water was selected as the working fluid. The purpose The IHX facility has several duct. And duct is a rectangular shape. For shape preservation, it should be neither transformed nor damaged in an actual test. Therefore, SolidWorks Simulation based structural analysis was conducted for securing the integrity of IHX facility. The performance of intermediate heat exchanger were tested in IHELPS experimental facility. The characteristics of the prototype IXH in the SFR design concept were preserved in IHELPS experiments followed the scale-down rules. By using the SolidWorks Simulation program, the stress on inner duct of IHX were analyzed. The analytical results showed satisfactory performance of the scale-downed IHX in comparison of ASME VIII Div.1 criterion. The CFD calculation results showed that the integrity of the IHX were preserved under static and dynamic state conditions.
