Abstract
<jats:p>The Master’s thesis is structured into three main sections: a general introduction to nuclear energy and nuclear reactors, an overview of HTGR reactors and their operating principles, and the application of this technology in cogeneration plants. The first section explains nuclear reactions, the components of a reactor, as well as its operating principle and the classification of nuclear power plants. The second section covers the description of TRISO fuel and the operating principle of HTGR reactors, with particular emphasis on safety, as it represents one of their most important characteristics. The final section of the thesis concerns the integration of HTGRs into cogeneration energy systems, including a brief consideration of the economic aspects of this technology.</jats:p>
