Study the Effect of Gd2O3 on the Neutronic Characteristics of Boiling Water Reactor using MCNPX Code

Abstract

MCNPX code (Monte Carlo N–Particle code extended) is used to design Boiling Water Reactor (BWR) bundle model. This model is designed to study the effect of Gd₂O₃ on the reactivity effect of voiding, void coefficient, neutron flux and normalized power. The incorporation of Gd₂O₃ directly into the UO₂ fuel is the most attractive process, because of its significant effect on the fuel life in the core of the reactor. The effect of axial fuel enrichment on the normalized power is analyzed. In this study, the influences of the burnable poisons on the main parameters of the reactor such as multiplication factor and burnup are investigated. Results are discussed to assess the effect of Gd₂O₃ on fuel cycle characteristics.
