This study shows the feasibility of using Erbium as a burnable absorber (BA) in the VVER-1000 reactor. Nowadays, Gd2O3 is commonly used BA in the form of additive compounds in the nuclear fuel for light water reactors. This analysis compares standard gadolinium absorber with a variant of absorber made of erbium in several forms. It is focused on the reactivity decrease and relative power of fresh fuel assemblies. The main aim of this study is to investigate neutronics properties of Erbium as the burnable neutron absorber and the possibility of the use in VVER-1000. Base on the Serpent calculations, a new type of fuel assemblies with Erbium absorbers are designed. |
