Effect of urea on the dissolution of U, UO2, and U3O8 in concentrated HNO3 and on the release of nitrogen oxides
Creators
Description
Adding urea during dissolution of U, UO2, and U3O8 in 12 M HNO3 suppresses the release of nitrogen oxides. However, the dissolution sharply decreases for metallic U (the maximal rate decreases by ∼2 times for a urea concentration of 30 g/liter), slightly decreases for UO2 (the dissolution decreases by 1.06 times for 20 g of urea per liter), and is practically unchanged for U3O8 (30-50 g urea per liter)
