Benchmark problem is considered associated with determination of thermo-mechanical stresses in the region of a tee where the interaction of hot sodium jet with cold sodium flow occurs. Using the results of a thermo-hydraulic analysis swings and frequencies of temperature pulsations on the wall of the pipeline are determined. The analysis of stresses, cyclic strength calculation and analysis of cracks progress under specified initial defect for the pipeline element were performed using the obtained data.
