dc.description.abstractThe nuclear fuels of urania (UOV and 5% and 10% gadolinia (Gd203) containing U02 previously produced by sol-gel technique were coated with first boron nitride (BN) then boron (B) thin layer by chemical vapor deposition (CVD) and also by plasma enhanced chemical vapor deposition (PECVD) techniques to increase the fuel cycle length and to improve the physical properties. From the cross-sectional view of BN and B layers taken from scanning electron microscope (SEM), the excellent adherence of BN onto fuel and B onto BN layer was observed in both cases. The behavior of fuel bumup, depletion of BN and B, the effect of coating thickness and also Gd203 content on the bumup performances of the fuels were identified by using the code WIMS-D/4 for Pressurized Water Reactor (PWR) and Boiling Water Reactor (BWR) cores. The optimum thickness ratio of B to BN was found as 4 and their thicknesses were chosen as 40 pm and 10 pm respectively in both reactor types to get extended cycle length. The assemblies consisting of fuels with 5% Gd203 and also coated with 10 pm BN and 40 pm B layers were determined as candidates for getting higher bumup in both types of reactors.tr_TR
