Abstract
The rewetting of a hot cladding surface following various anomalous nuclear reactor operating situations is governed by two-dimensional conduction in the cladding wall. A correlation in the form of the approximate analytical solution to the two-dimensional conduction problem is suitable for predicting the rewetting velocity, i.e. 1/v = ρc(T2-Tc)/ φeff. The physical basis of this equation is explained and arguments are presented based on more exact analysis as to why wall thickness, wall thermal conductivity, rod diameter, heat generation rate, and coolant flow rate are not included.Keywords
