The article is devoted to mathematical simulation of NPP technological systems with the use a graphical editor of mathematical models for computer code Cortes and Korsar used in the SC "Atomproekt". This software allow to make calculations of physical parameters of systems and their interaction, which is necessary for project solutions verification throughout the life cycle of NPP. However, the existing way of building and editing models causes some difficulties. Mathematical model represents big text file that doesn’t provide a visual representation of system being simulated. This method causes time delay in the work because of the error appearance and also doesn’t allow to interpret the results or organize complex calculations easily. Developed graphical editor of models allows to solve such problems. Unified interface allows engineer to interpret model and calculation results easily. Signal base could organize complex calculations of few models automatically.
