Simulators for nuclear power plants

Nuclear power plant simulators Our company has developed, built, maintains and continuously develops simulators for both Czech nuclear power plants. They simulate in real time and in great detail the functions of most power plant equipment in the almost complete range of their operating modes and are equipped with a full-fledged replica of the control room. It is used primarily for the training of operators, which allows them to practice standard equipment operation and the management of non-standard situations or accidents.
