dc.description.abstract© 2019 Published under licence by IOP Publishing Ltd. The problem of the use of burnable absorbers (BAs) in VVER-type reactors is considered to reduce the volume of "liquid" regulation of excess reactivity margin for fuel burnup. As such, natural gadolinium and europium are considered in the form of Gd 2 O 3 and Eu 2 O 3 , placed in integrated form with uranium fuel in fuel rods. The ratio of fuel rods with BAs and conventional fuel elements is 1:6. Variants of both the homogeneous location of the BAs and heterogeneous, including for the mixed use of these BAs were considered. The strong influence of the BAs composition and their location in the fuel elements on the dependence of the multiplication factor on fuel burnup is shown.
