Urânio: um estudo de caso

Abstract

This essay explores the course of uranium from its discovery by Martin Heinrich Klaproth to its initial applications in weapons of mass destruction, and further to its future as a clean energy source in the global energy balance. It analyzes the relevance of uranium on a global scale as an essential component in nuclear energy production, addressing its social, economic, and environmental impacts. Examples such as China and Brazil are discussed, highlighting the importance of maneging the demand for nuclear energy as a low-carbon source and the responsibility to mitigate adverse impacts, emphasizing sustainability and the adoption of strategies aligned with ESG – Enviromental, Social and Governance goals. Furthermore, through data analysis and graphics, a growing demand for uranium in nuclear energy is observed, aiming for its potential to reduce carbon dioxide emissions into the atmosphere and promote energy autonomy in several countries. Significant technological advancements, such as fourth-generation (IV) reactors and modular reactors, are examined, contributing to making nuclear energy more competitive compared to other energy sources. These innovations represent a significant step towards a more sustainable and less carbondependent energy landscape.
