This paper deals with transient thermal — stress analysis of concrete structure around the nuclear reactor loaded by dead load and thermal loads. The FEM simulations were performed for various input materials characteristic of concrete based on experimentally obtained physical-mechanical properties and measuring of temperatures. The proposed calculation model, procedures of numerical simulation have been describing conclusions of analysis. The numerical simulation has been performed by means of the finite element method (FEM) using a commercially available ANSYS code.
