Celsist Subchannel Module Aided Simulation of Liquid-Metal Coolant Flow in Experimental FA

  • Published:
Atomic Energy Aims and scope

The CELSIST subchannel module is described. The results of the simulation of experiments on the flow of liquid metal coolant in model FA are presented: lead-bismuth eutectic alloy in a 19-rod FA on the THEADES stand (Karlsruhe Liquid Metal Laboratory, Germany), sodium in a 19-rod FA on the Bundle 2A FFM stand (ORNL, USA), sodium-potassium eutectic alloy in a 37-rod FA on the 6B stand (IPPE, Russia), sodium in a 37-rod FA with partial blockage of the flow section (Oarai Research Center, Japan). The computed temperature of the coolant and the cladding of fuel-rod simulators are compared with the experimental temperatures.
