Ribs contacting the surface of reactor assemblies insulate the surface and cause local reductions in coolant velocity resulting in local heat flux perturbations. These perturbations can be represented as a reduction in the burnout heat flux for surfaces contacted by a spacer rib as compared to an ideal surface, i.e., no rib present. This memorandum presents results of burnout tests with insulating ribs on aluminum surfaces and proposes a method for applying the results to reactor assemblies. 1 ref., 7 figs., 1 tab.
