The results of modeling the flow and heat transfer of a liquid metal coolant in experimental fuel assemblies using the CELSIST sub-channel module are presented: lead in a 169-rod fuel assembly at the EUST facility (NIKIET), sodium-potassium eutectic alloy in a 37-rod fuel assembly at the 6-B stand (SSC RF - IPPE), Rose alloy in a 7-rod fuel assembly at a facility at the IT SB RAS, eutectic lead–bismuth alloy in a 19-rod fuel assembly, with partial blocking of the fuel assembly cross section, at the THEADES facility (KALLA Laboratory, Karlsruhe Institute of Technology, Germany). The calculated pressure drop on the assembly as well as the temperature of the coolant and cladding of fuel-rod simulators, are compared with experimental data.
