2020-5-8Nuclear energy is used to produce electricity without the adherent CO2 emissions to which fossil fueled power stations are prone. Nonetheless the process does produce highly radioactive residues from the enriched uranium fuel these normally being stored in sealed containers at the power plants. The building of nuclear power stations went through a downturn following the Chernobyl
