Description

Due to its neutron economy, versatility of fuel channel and simplicity of fuel bundle design, CANDU reactors have a unique ability of efficiently using alternative fuel, such as: depleted uranium (DU), recycled uranium (RU), mixed oxide of Thorium and Plutonium ((Pu,Th)MOX) and natural uranium equivalent (NUE). This paper outlines the results on the investigation of two analysed cases (NUE versus 37S) with ELESIM computer code, aimed to evaluate the fuel behaviour in normal operating conditions. ELESIM computer code estimates the nuclear fuel elements performance parameters, for a given history power, using one-dimensional models for heat generation, temperature distribution, fission gas release and pellet to sheath heat transfer. The fuel bundle power distribution respectively for each ring corresponding to a fuel channel was obtained with LEGENTR3D, WIMS and DRAGON programs. (authors)
