Since the 21st century, the closure of domestic uranium mines in Europe has made it one of the world's leading importers of uranium. In recent years, a series of policy adjustments have led to an improving situation for enriched uranium supply, yet the challenge of natural uranium supply remains...

The release of uranium from uranium tailings into the aqueous environment is a complex process controlled by a series of interacting geochemical reactions. In this paper, uranium tailings from a uranium tailings pond in southern China were collected at different depths by means of borehole...

The concentrations of uranium and nine elements (As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn) in snow and rainwater samples were determined. Samples were collected in Thessaloniki-northern Greece in three sites, one in the industrial area close to an oil production power plant and two in the centre of...

Although plutonium has been studied by different disciplines (such as technology and innovation studies, political sciences) since its discovery, back in 1940 at the University of California (Berkeley), the resource and environmental economic literature is still relatively scarce; neither does the...

This paper establishes the feasibility of Low-Enriched Uranium fueled Nuclear Thermal Propulsion (LEU-NTP) reactors in the low-thrust region below 16klbf (71kN). A reference, 7.5klbf, HEU design is converted to 19.75% enriched LEU and shown to be capable of reaching criticality and meeting other...

Although recent studies have detected elevated concentrations of arsenic and uranium in inland, alkaline, saline lakes, the chemical reactions associated with these enrichments are poorly understood. In this study, we used a five-year study of water chemistry, characterization of arsenic and...

Incorporating uranium into magnetite crystal from wastewater to limit its mobility have been proposed to the long-term remediation of radioactive contamination. Unfortunately, this process is accompanied by reduction or surface adsorption, which significantly reduces the incorporation capacity...

Mining and smelting of vanadium uranium ore results in the release and coexistence of vanadium and uranium in the environment, raising severe risks. The feasibility of synchronous removal of pentavalent vanadium (V(V)) and hexavalent uranium (U(VI)) was investigated in mixotrophic column reactor...
