Abstract
This article is devoted to numerical modeling of the hydrodynamics in the pressure header of a mockup of a VVER-1000 water–water energetic reactor. The mockup is made on a reduced scale and is a part of the hydraulic stand E7-ELEMASh of the Department of Nuclear Reactors and Installations of Bauman Moscow State Technical University. The test stand and the calculation method based on computational fluid dynamics (CFD) are described. The influence of the calculation model parameters on the calculation results is analyzed. The calculation model is validated according to the physical experiments. Recommendations are given on the choice of the calculation method for the analysis of flow in water–water energetic reactors and the creation of digital twins.
