Mathematical modeling of temperature stresses of heat-generating elements of elliptical cross-section
Aleksandr Kanareykin
Abstract
The work is devoted to improving the reliability of nuclear power plants. During operation, the fuel elements of nuclear reactors operate at sufficiently high temperatures. The heterogeneity of the temperature field leads to the appearance of so-called thermal stresses. The main objective of this work is mathematical modeling of temperature stresses of fuel elements of cylindrical and elliptical cross-sections reactors. Based on mathematical modeling, it was shown that the level of thermal stresses arising during the transition from a circular cross-section to an elliptical one decreases.
