The GEFEST800 software system developed for performing on-line calculations of the BN-800 reactor contains moduli for performing nonstationary neutron-physical calculations of a reactor, calculations of feedbacks via calculations of the temperature, burnup, residual heat release, evaluations of the activity of spent fuel assemblies, and so forth. The error of most computational parameters is determined. Moreover, the software can process experimental data while nonstationary processes are calculated and the energy releases of fuel assemblies measured. The GEFEST800 software-hardware system is implemented in the Winmod system shell, which makes it convenient for the user to organize pre- and post-processing as well as to perform analysis and enter corrections directly in the course of the computational process itself. The system shell makes it possible to analyze, via the windows construction procedure, the quality of a solution and perform calculations using a different module in a definite window space in order to compare the results of solutions performed by different methods at the indicated problem location.
