This Master's thesis dealt with securitization attempts related to the planned construction of a new reactor at the Dukovany NPP. Therefore, its aim was to find, analyse and explain securitization speech acts associated with the planned reactor, in the period from summer 2015 to December 2020 using the critical discourse analysis approach. The results show that securitization speech acts of this kind do appear in the Czech public sphere and are articulated mainly by four groups of actors: representatives of Austria, Czech environmental NGOs, Czech governmental representatives, and Czech political opposition. These actors have different goals: to stop the construction of the reactor, to implement the construction of the reactor, or to influence the way in which the construction will be implemented. One case of successful securitization was found in the outcome: The Czech government was able to enforce extraordinary measures that deviated from standard democratic processes using security-based arguments. Their goal was to implement the construction of the reactor. It remains to add that the research also revealed three important functional actors who co-created the discourse: the BIS secret service, the SÚJB nuclear safety office and the company ČEZ.
