Dukovany Power Plant Information Centre
The Dukovany Nuclear Power Plant is working towards maintaining permanent good relations with its neighbourhood, and is open to the wider public. Since 1990 citizens have taken the opportunity of visiting the Information Centre of the power plant. About 30 thousand visitors come every year to see the Information Centre. Just come in and see us to have a look!

The Dukovany Nuclear Power Plant, with its installed capacity of 1,760 MW, is the second largest nuclear power plant in the Czech Republic. Construction of the nuclear power plant made certain impacts on the life of the surrounding region. New people came from various parts of the country. The initial region became suddenly different. Something went down, and something new has been built. Despite the fact that the construction boom, and the subsequent operation of the power plant only influenced the life of inhabitants in its surroundings, the electric energy produced by the power plant is consumed across the whole country. Therefore, the modern Information Centre was established and opened to the general public. Professional guides working in the Information Centre provide visitors with an erudite explanation on the power plant and nuclear power engineering. All visitors can acquaint themselves on the exhibited models with the reactor and the reactor unit, deposition of spent nuclear fuel and other technical information. All visitors can take the opportunity to formulate a real idea on the functionality of the nuclear power plant using modern state-of-the-art audio-visual techniques.
- Model of the reactor – Function of the control rod assemblies and system of the automatic regulation of the reactor performance
- Model of the reactor core (Scale 1:1)
- Model of a CASTOR 440 container – Storage and transport of spent nuclear fuel
- Movable model showing manipulation with spent nuclear fuel
- Model of the main production unit – It enables understanding the nuclear power plant as a complex but logical and functioning system
- Layout of the entire power plant, including the detailed pictorial and word explanation
- Printed information materials
You can get the most information in the shortest time by seeing the exhibits situated directly in the object of the Information Centre. Here we namely offer information on the power plant but also general information on nuclear power plants and nuclear power engineering. The excursion takes about one hour, or one and half hour if the accompanying movie programme is included.
Review of exhibits placed on the ground floor
Working clothes fashion show
Samples of two sets of working clothes, including personal dosimeters, are displayed on dummies. These exhibits show the protective clothes for use in emergency situations and the working clothes for work in the controlled zone.
Map of the world
A map of the world including a presentation of the individual reactor types that are operated across the world.
The world’s most operated reactor types are shown here
The Chernobyl meltdown
Description of the Chernobyl meltdown that happened on 26 April 1986. Chernobyl used Type RBMK reactors, i.e., boiling graphite reactors the physical properties of which are not the best. The disadvantages of these reactors were known already before construction of the power plant. The reason why they were constructed was a high production of isotopes of elements suitable for nuclear weapons. This type of reactor operates on quite different principles than the reactors installed in our country. The Chernobyl meltdown was a result of human failure, and it negatively influenced the attitude of people on nuclear energy as such.
International scale for assessment of events in nuclear power plants
The scale introduced by the Atomic Energy International Agency in 1991. The scale includes 7 orders of magnitude. Orders of magnitude 0-2 have no effect on the power plant surroundings. Orders of magnitude 3-4 mean a small-scale leakage outside the power plant. Orders of magnitude 5-7 represent a large-scale effect on the power plant surroundings. The worst event at Dukovany was happened in 1992 and was graded with a 2 order of magnitude thanks to a switching room failure at Slavětice.
Passive safety scheme
The barriers that prevent leakage of radioactive substances into the life environment are shown here. The first barrier is formed by the hermetically sealed fuel rods. The second barrier is formed by the tight primary circuit, and the third barrier is the containment consisting of the hermetic boxes with the barbotage.
Safety system scheme
The power plant project is designed in such a manner so that the standards are not overrun, even in case of generating the maximum-scale project accident possible, specifically a disruption of the primary piping in the Dukovany Nuclear Power Plant. Two kinds of safety systems are shown. The first system prevents fuel from re-melting in the reactor core, and the second system serves for the generation of vacuum in the hermetic boxes.
Reactor core model
The model of the reactor core is made in the scale 1:1. You can enter from both sides of the model or you can stand inside the model. The lower part displays the 312 fuel assemblies. There are 37 control rod assemblies placed in the upper part. When the model is started up, you will learn what happens inside the reactor in the course of ten-and-half-month’s operation.
The model of the reactor is made in the scale 1:1. The real reactor is approximately 24 m high. The scale allows recognition of even the relatively small details of the reactor structure.
Fuel assembly model
A model of the hexagonal fuel assembly, the real height of which is 3.20 m. Inside the fuel assembly 126 fuel rods which include ceramic tablets of uranium dioxide are placed.
The charged particles in the chamber attract small drops of mist and form visible traces. The length and structure of the traces determine the kind of particles. The thicker and the shorter traces are formed by alpha particles, the thinner and the longer traces are formed by beta particles.
In the course of our life we are exposed to radiation and therefore we absorb a certain radiation dose every year. Its base consists of the natural background radiation and the remaining radiation is formed by our style of living. There are various kinds of radiation and the related radiation doses shown.
The probe is a proof of the fact that radiation can be measured in a certain way. Uranium ore that releases radiation is placed in small dishes. If the sample is placed under this probe, the scale shows the intensity of radiation released from the sample.
Here you can verify your knowledge of physics. The red column includes faces of discoverers, the green column their names, the yellow column includes their discoveries. You can try to link the faces to names and discoveries. If the answers are correct, the bell starts ringing and the panel illumination turns off.
Power Plant layout model
This model shows building objects situated on the 126 hectare area of the power plant which can be selected by means of push-buttons. When pressing the push-button, the object is illuminated, its picture is shown on the monitor and an explanation can be heard.
The model shows the basic machines and equipment, and their mutual links. The equipment is divided into three functional circuits by means of which electric energy is produced in the Dukovany Nuclear Power Plant.
The model of a CASTOR 440 container intended for transport and storage of spent nuclear fuel.
Dukovany Nuclear Power Plant Information Centre
The excursion takes about two hours and is available free of charge for all visitors. For the duration of the entire excursion you will be accompanied by two professional guides. You will watch an interesting movie about energy and see models of the entire power plant and some related facilities, and you can even become “the fuel” inside the model of a reactor core built in the scale 1:1.
Group visits (more than 15 persons) should be booked in advance.
