description: This study includes an analysis of the VVER-1200 reactor pressure vessel under thermal shock conditions. Thermal shock (stress) can lead to excessive temperature gradients on materials resulting in excessive stresses. These stresses may consist of tensile stress, which is the stress due to forces acting in opposite directions, tending to break the material, and compressive stress, which is the stress due to forces acting in opposite directions, tending to compress material. These stresses, cyclic in nature, can lead to fatigue failure of materials. An analysis was made of the processes that can occur in the event of a thermal shock in the reactor pressure vessel. The analysis results are compared. The study was carried out in a computer environment on a model of the VVER-1200 reactor vessel, which will be used at the Akkuyu NPP under construction in Turkey. ANSYS Fluent was used for analysis and SOLIDWORKS was used for 3D design. The data obtained as a result of calculations are discussed with a comparative analysis and interpretation of the results obtained.
