A parametric, hybrid reduced order model approach based on the ProperOrthogonal Decomposition with both Galerkin projection and interpolation basedon Radial Basis Functions method is presented. This method is tested against acase of turbulent non-isothermal mixing in a T-junction pipe, a common owarrangement found in nuclear reactor cooling systems. The reduced order modelis derived from the 3D unsteady, incompressible Navier-Stokes equations weaklycoupled with the energy equation. For high Reynolds numbers, the eddy viscosityand eddy diffusivity are incorporated into the reduced order model with aProper Orthogonal Decomposition (nested and standard) with Interpolation(PODI), where the interpolation is performed using Radial Basis Functions. Thereduced order solver, obtained using a k-{\omega} SST URANS full order model,is tested against the full order solver in a 3D T-junction pipe with parametricvelocity inlet boundary conditions.
