Teodora Retegan

Docent at Chemistry and Chemical Engineering, Energy and Material, Nuclear Chemistry

Teodora's competence area is solvent extraction of metals, primarily from spent nuclear fuel for separation of actinides from lanthanides for further transmutation. She is also developing competence in safety related issues for Gen IV systems. Other application of her competence area is in recovery or recycling of valuable metals (platinum group metals, lanthanides, etc) from different sources, like electronic waste (WEEE).
