Abstract
This article presents the results of a computational and theoretical analysis of reducing the consumption of natural uranium in VVER-type reactors with an erbium burnable absorber when reusing spent fuel. Calculations were carried out on a simplified model of fuel burnout in a reactor using partial refueling without fuel assembly permutations. A comparative analysis of the consumption of natural uranium when using gadolinium and erbium as burnable absorbers for options with uranium and REMIX fuel was carried out. It has been shown that for options using REMIX fuel, the loss in natural uranium consumption when using erbium compared to the option with gadolinium is reduced by 50%.
