A SIMULATION METHOD FOR THE TEMPERATURE AND HEAT FLUX OF DUAL-COOLED, ANNULAR, NUCLEAR FUEL ROD

摘要

PURPOSE: A method for simulating the heat flux and temperature of a dual cooled annular nuclear fuel rod is provided to directly be used for an annular nuclear fuel development. CONSTITUTION: A calculated internal and external surface heat flux is compared with the supposed heat flux(S210). The flux distribution is recalculated by using the converged internal and external surface heat flux(S220). The calculated internal and external flux is compared with the supposed flux(S230). The converged internal and external flux, the heat flux, and a gap thermal conductivity, and a nuclear fuel temperature are stored(S240).
