Activity and self-shielding coefficient Calculations of Europium oxide (Eu2O3) in a hypothetical nuclear reactor

Abstract

The elements are generally characterized by various cross-sections for interaction with particles and the effect of this reaction shows the number of elements with large cross-sections for interaction with neutrons in particular, so this effect must be studied on the materials that make up the core of the nuclear reactor, especially the elements with large cross-sections. Theoretical studies The characteristics of Europium oxide (Eu2O3) have been widely researched. Europium-153 makes up 52 percent of natural europium, with europium-151 accounting for the other 48 percent. Because of its ability to absorb neutrons, europium is primarily used in nuclear reactor control rods. Other usage have been limited due to its scarcity and high cost. This research included mainly to study the activity of Europium oxide for different Thickness of Radius in radial and axial distribution. Calculations of self-shielding coefficients and its effects clarify that this material wildly uses in a nuclear reactor as control rod elements, in particular the compound with large absorption cross-sections of the neutron. It is critical that it is compatible with its cladding alloy.
