Review of methods applicable to the calculation of gap conductance in Zircaloy-clad UO2 fuel rods
Description
The program GAPCON-THERMAL-1 solves the steady-state temperature distribution in a reactor fuel rod by iterating on converging choices for the gap conductance. This conductance is calculated via a modification of the Ross--Stoute model. A review is made of data and calculational methods (in addition to those of Ross and Stoute) which are applicable to gap conductance. Various approaches to calculating the conductance through the gas and the conductance through contact points are compared. Conclusions and recommendations for the GAPCON program are presented. 15 references. (U.S.)
