Sustainability of uranium extraction – a discussion

Nuclear power has been declared a green technology within the scope of the EU taxonomy. However, this decision did not take into account the mining of uranium and the final disposal of uranium products.  The different methods for mining uranium and their effects on the environment are discussed in this paper.
