The knowledge gaps and modelling challenges in LMFR are primarily related to two facts. Firstly, the heat transfer characteristics of liquid metal are markedly different from that of conventional fluids (air and water) due to the extremely high thermal conductivity, which makes the heat transfer predictions of conventional turbulence models invalid under most conditions. Secondly, the pool-type reactor designs and the presence of a cover-gas region give rise to thermal hydraulic phenomena which are unique to such reactors.
In this project, we carry out the following investigations: (i) Modelling of Aerosol Dynamics in the Cover Gas Region of a LMFR; (ii) Modelling of the hot plenum of E-SCAPE; (iii) Modelling of the forced and mixed convection in the TALL3D facility; and (iv) Modelling of the thermal striping in a T-junction.
