The modern direction in the study of safety nuclear power plants is to ensure maximum level detail process modeling with a satisfactory computational resources. One approaches such task solving coupled use special software required levels detail, for example, systemic thermohydraulic codes hydrodynamics codes.
 This article describes developed coupling module between system code RELAP5/Mod...

Magnetohydrodynamic (MHD) phenomena, due to the interaction between a magnetic field and moving electro-conductive fluid, are crucial for design of magnetic-confinement fusion reactors and, specifically, breeding blanket concepts that adopt liquid metals (LMs) as working fluids. Computational tools employed lead fusion-relevant physical analysis, but dedicated MHD code able simulate all phenome...

Today, most software applications, also in the nuclear field, come with a graphical user interface. Recently, the Symbolic Nuclear Analysis Package (SNAP) was designed to simplify the process of performing safety analysis. The purpose of the present study was to develop an SNAP animation model for RELAP5 calculations of a nuclear installation. The facility selected was the Rig of Safety Assessm...

A RELAP5-3D model has been developed for the RBMK Kursk 1 NPP. The primary features of this model are the three-dimensional neutronics model of the reactor core and the user subroutine that generates the neutron cross-sections. This subroutine contains the same neutron cross-section libraries that are presently being used in the Russian STEPAN/KOBRA calculations. The implementation of the neutr...
