Effect of fuel assembly rotation on optimization of fuel pins burnup

Abstract

The paper’s topic is the optimization of fuel assembly burnup in the Dukovany Nuclear Power plant using fuel assembly rotation . The MOBY-DICK deterministic code was used to simulate neutronics processes within the core reactor. This study evaluates the impact of fuel assembly rotation on the homogeneity of fuel pin burnup for overall fuel utilization optimization. The results of this study demonstrate how the rotation of fuel assembly affects burnup distribution and contributes to the more efficient use of nuclear fuel.
