This map layer shows the locations of nuclear power stations and research reactors against the background of the country-specific risk of danger to the population through natural hazards in 2017. There are five categories of risk of natural catastrophes.
Natural hazards or catastrophes can cause so much damage to nuclear power plants and research reactors that the release of radiation endangers the safety of the population.
Additionally, in the case of a disturbance of the safety installations, illegal access to radioactive material may become easier. The hazards that can result from a damaged or not optimally working nuclear power plant do not stop at a country's borders, and the risk of single natural catastrophes occurring may be different in different parts of a country. Therefore, this map can only be understood as an indication of the danger nuclear power plants pose to the population in case of a natural hazard.
The danger to a country is expressed as the exposure of the population to accumulated natural hazards (earthquakes, hurricanes, floods, droughts and rising sea levels). The degree of exposure of a country is calculated by determining the number of people affected by each natural hazard in that country, adding them up and dividing the sum by the number of inhabitants of the respective country.
