Specification
Uranyl nitrate (solid) (10102-06-4) also can be called for Uranyl nitrate ; Uranyl nitrate (solid):(bis(nitrato-o,o')dioxouranium) ; Uranyl dinitrate ; Uranyl(2+)nitrate,solid ; UO2(NO3)2 . Uranyl nitrate (solid) (10102-06-4) is a yellow-green solid and it's hygroscopic. Uranyl nitrate (solid) (10102-06-4) is an oxidizing and highly toxic compound and should not be ingested; it causes severe renal insufficiency and acute tubular necrosis and is a lymphocyte mitogen. Target organs include the kidneys, liver, lungs and brain. It also represents a severe fire and explosion risk when heated or subjected to shock in contact with oxidizable substances.It was used to fuel aqueous homogeneous reactors in the 1950s. However it proved too corrosive in this application, and the experiments were abandoned. Uranyl nitrate (solid) (10102-06-4) is important for nuclear reprocessing; it is the compound of Uranium that results from dissolving the decladded spent nuclear fuel rods or yellowcake in nitric acid, for further separation and preparation of Uranium hexafluoride for isotope separation for preparing of enriched Uranium .
