The objectives and problems of modeling systems in developing nuclear thermionic power plants for use in space are discussed. The basic data of the modeling codes and systems developed in the process of creating the Enisei SNPS are presented. The principles of safe integration of a control digital computer into the control circuit of NPP are described and the results of experiments on the development of standard transient regimes in nuclear power tests are presented. The developed multicomputer distributed simulation system is presented, and the results of experimental testing of a scale model of the automatic control system in a wide range of operating modes are given.
