PhD Topic: CFD modeling of two-fluid loops Dual Fluid Reactor (DFR) mini-demonstrator
Supervisor: prof. dr hab. Konrad Czerski (University of Szczecin & NCBJ, Poland)
The dual fluid reactor contains two separate fluid loops: one for the fuel and another for the coolant. The molten salt reactors use the same fuel for both and the appropriate test facilities have already been constructed including the reactors themselves. This is not the case for the DFR. Despite there exist molten metal cooled reactors and in particular – lead-cooled reactors – they were tested for cooling a solid fuel which is different. So far, no facility which would contain two different fluids in a reactor system has been constructed. The task of this project would be to work out the geometry and thermal hydraulics of a very simple CFD (computational Fluid Dynamics) DFR model – the Mini-Demonstrator – which would allow the flow of two neighboring tubes with molten (and depleted) uranium (or its eutectic) cooled by molten lead. The calculations should be performed for the fluid tubes which are made of carbides (SiC, ZrC etc.).
