TL;DRAbstract

Containment liner-concrete interface heat transfer phenomena are investigated. In particular, the effects of thermal radiation and natural convection heat transfer as well as the effects of anchors on the liner-concrete conductance are studied. The need for a thorough structural analysis to determine the spatial distribution of the gap between the liner and concrete has been found to be necessary before the liner-concrete conductance can be accurately defined. A reasonable minimum value for a one-dimensional liner-concrete interface conductance of 57 W/m/sup 2//K has been established; reasonable maximum value is 2,800 W/m/sup 2//K.
