The article presents a developed calculation model for fuel elements of nuclear reactors.
This model includes complex of interconnected verified techniques and materials proper-
ties to be used in calculations, in particular: technique of fuel elements stress and strain
state calculations; technique of model verification and fuel elements material properties
using experimental data; technique of fuel elements stress and strain state probability
calculations; technique for justification of fuel elements operability.
Keywords:
nuclear reactor, fuel element, stress and strain state, finite element method.
