Energy security in the context of nuclear energy - threat analysis with the use of the GIS tools

This article presents Poland's approach to energy security in legal acts, possible threats for the environment posed by construction and exploitation of a nuclear power plant, and threats posed by human's direct activity, to which a separate chapter is devoted. This article also shows the potential of the Geographic Information System (GIS) tools, which enable not only gathering spatial data, but also processing and visualising it. The aim of the geoinformation systems is data analysis, which eases decision-making.
