CONV

2D (CONV2D) and 3D (CONV3D) hydrodynamic computer codes were developed at IBRAE for analysis and prediction of hydrodynamic flows in normal and emergency operation modes for various reactor installations and for direct numerical simulation of heat-and-mass transfer processes and the melt behavior at reactor vessel bottom when analyzing severe accidents at NPP. The CONV package was transferred to Rosatom design and industrial enterprises for trial operation and preparation for certification.
