The application makes it possible to become familiar with the design and the power generation technology on the contemporary nuclear power plant of the Russian design of 3+ generation. It shows the resistance to the extreme external influences (earthquake, explosion and falling of flying object, snow loads) in the interactive mode and also with the operation mode of the security systems in the emergency mode (rupture of the pipeline). It gives a possibility to the user to stop and to start nuclear reaction. The application is based on technological solutions of the project «AES-2006», developed (created) by JSC «ATOMPROEKT».
