the removal of uranium and any other heavy metals from wastewater might be achieved via several chemical or physical treatment techniques. biosorption process has been considered as a potential alternative way to remove contaminants from industrial effluents. moreover the surface of biosorbent was characterized by sem. the biosorption characteristics of uranium (vi) on pretreated a. niger were ...
Defects such as the most stable hexavacancy (V6) distribute widely on neutron-irradiated graphite surfaces, which play a dominant role in immobilizing radioactive products released from nuclear fuels. By performing DFT calculations, we explore the interaction of gaseous uranium dicarbide (UC2) molecules on a graphene nanosheet with a V6 defect, in order to investigate the behavior of the repres...
The interaction of thermal neutrons with U results in fission with a probability of 85% and in the formation of U (t1/2 = 2.3 10 yr) with a probability of 15%. While anthropogenic U is, therefore, present in spent nuclear fuel at levels of U/U up to 10 , the expected natural ratios in the pre-anthropogenic environment range from 10 14 to 10 . At VERA, systematic investigations suggest a detecti...
The new research reactor of the Technische Universität München will provide the German needs of neutrons for the beginning of the next century. High intensities of thermal neutrons are provided by a particular densely packed core of highly enriched uranium and are extracted by 12 beam apertures. The low thermal power of 20 MW allows the positioning of a D2 cold source at a maximum of the therma...
