This research aims to increase the efficient usage of nuclear fuel. It analyses the possibility of axial optimization of a fuel pin containing a Gd2O3 burnable absorber. The work deals with the effect of shortening (one-sided and double-sided) the fuel pin with Gd2O3 burnable absorber. Analysis of the effect on the power distribution was presented. Furthermore, it investigates the effect on stability during xenon oscillations and selected reactivity coefficients. The study performed a set of variations with different axial shortening of the Gd2O3 fuel and replacement of the fuel parts without the burnout absorber. For the evaluation, a special reference fuel loading pattern was designed and calculated by MOBY-DICK diffusion macro-code.
