High-temperature interaction of uranium mononitride with ...

The interaction of uranium mononitride UN with a refractory metal (rhenium) is studied in the temperature range 1773-2273 K. The coefficients of uranium diffusion from UN into polycrystalline and single-crystal rhenium and their temperature dependences are determined. The diffusion mobility of uranium in rhenium is shown to be lower than that in molybdenum and to be higher than in tungsten.

Rhenium concentrations were measured in the Black Sea to determine the behavior of this redox-sensitive element in an anoxic basin. Under reducing conditions, Re is removed from solution, leading to its depletion from Black Sea deep waters. Compared with uranium, water column Re and Mo profiles show evidence of removal from mid-depths, suggesting that these elements are scavenged either in …
