Reaction Steps

In the production of uranium dioxide nuclear fuel pellets, a substantial quantity of uranium dioxide fuel stock powder and some scrap or broken pellets are routinely recycled for reasons of economy and environmental protection. Recycling of the uranium dioxide materials is carried out by dissolving the solid uranium dioxide material in nitric acid, and thereby forming a solution of soluble uranium nitrate. The pH of a water-diluted solution of the soluble uranium nitrate is reduced to about 5 to about 7 with ammonium hydroxide, and then the uranium is precipitated from the solution by the addition of hydrogen peroxide to produce insoluble uranium peroxide according to the reaction:
