Abstract: Crushed salt can be used as a backfill in salt repositories to bury and conduct heat away from radioactive waste in salt repositories. Since crushed salt compacts during reconsolidation, its thermo-physical properties will vary because of changes in porosity. A Hot Disk Transient Plane Source thermal constant analyzer was used to measure thermal conductivity of the salt samples. Thermal conductivity was found to decrease with increasing temperatures.
