Ground floor

The ground floor features an interactive walk-through exhibition, which uses modern techniques to bring energy and energy technologies closer to visitors. The aim is to provide a comprehensive coverage of this complex topic by using advanced approaches and by encouraging visitors to take an active role.


Have a look at some of the most interesting scale models and interactive exhibits:



Check your carbon footprint

This interactive exhibit enables visitors to check the average carbon footprint in Slovenia and to find out what kind of lifestyle causes the largest increase in carbon emissions. Visitors also get a few tips how they, as individuals, can minimize their carbon footprint.


Comparison of power sources

A very illustrative example of the amount of fuel (uranium, coal and fuel oil) used by power plants of the same capacity in the course of 8 operational hours.


What’s behind the power socket?

Easily trace the path of electric current back from the power socket in the house, through transmission lines and transformers, to the power generator at a power plant.


Energy mix

The mission of this multiplayer computer game is to follow the daily load curve as accurately as possible by steering the power production at 6 different types of power plants. Players also need to make sure the selected combination has a minimum effect on CO2 emissions and the price of electricity.



This exhibit provides an interesting display of the changes in the potential energy of water, which is pumped up by hand and then released down, generating the kinetic energy that drives the water turbine.


Solar power

This is an instructive practical display of two ways of harnessing solar power: using a solar collector for heating water and a solar panel for generating electricity.


Wind power

This exhibit clearly demonstrates how electricity is generated using a wind turbine and how the wind speed and blade pitch affect the efficiency of the electricity generation.


Cloud chamber

The electromagnetic radiation comes in a very wide spectrum. Different regions of the spectrum are observed differently. The ionizing radiation, like radio waves, cannot be detected using our senses. However, we can, measure and visualize it using instruments like the cloud chamber.


Geiger-Müller counter

Radiation is a natural phenomenon where energy radiates from the source of radiation in the form of electromagnetic waves or in the form of particles. Based on the electromagnetic spectrum, radiation is divided into two types: the ionizing and non-ionizing. The ionizing radiation comprises the radiation from radioactive materials (alpha, beta, gamma) and X-ray, neutron, cosmic, and to some extent also the ultraviolet radiation.


Large 3D scale model of the Krško Nuclear Power Plant

Explore the 3D scale model of the Krško Nuclear Power Plant by moving the sliding touch screen along as you go. In eight positions various technical specifications or descriptions of individual facilities will be displayed on the touch screen and widescreen LCD monitor.


Model of the reactor vessel

Take a closer look at the model of the reactor vessel, with reactor core, where the controlled uranium fission chain reaction takes place. Enclosed inside a containment building, the reactor vessel supplies thermal power to the power plant.


Nuclear fuel and nuclear fuel cycle

A graphical and textual presentation of the nuclear fuel cycle: from uranium ore mining, conversion into yellowcake, uranium enrichment, fabrication of fuel assemblies, storage of spent fuel, fuel reprocessing, to the disposal of high-level radioactive waste.The Krško Nuclear Power Plant uses nuclear fuel in the form of uranium dioxide pellets. Pellets are encased in a hermetically sealed metal tube called a fuel rod. Fuel rods make up fuel assemblies. A fuel assembly skeleton consists of control rod guide thimbles, which are firmly fixed into top and bottom nozzles, and grid spacers, which provide lateral support to fuel rods.

Opening hours:

  • Tuesdays between 10:00 and 17:00,
  • Wednesday - Friday between 10:00 and 15:00
  • first Saturday of the month 10:00 - 17:00.


Booking is essential for schools and groups. By booking your visit, you reserve your preferred time slot and a guide to show you around the centre.



Admission to the World of Energy interactive centre is free for individuals as well as groups.
