Abstract
Compositions are provided that include nuclear fuel. Methods for treating nuclear fuel are provided which can include exposing the fuel to a carbonate-peroxide solution. Methods can also include exposing the fuel to an ammonium solution. Methods for acquiring molybdenum from a uranium comprising material are provided.
Claims18
A method for acquiring molybdenum from irradiated nuclear fuel, the method comprising:
- exposing the irradiated nuclear fuel to an aqueous solution to form a mixture comprising a solid phase and a liquid phase while maintaining the pH of the liquid phase at from greater than 7 to less than 10;
- separating the solid phase from the liquid phase;
- and
- exposing at least a portion of the liquid phase to an adsorbent to remove at least some of the solute from the liquid phase and form an effluent containing the molybdenum.

A method for acquiring molybdenum from irradiated nuclear fuel, the method comprising:
- exposing the irradiated nuclear fuel to an ammonium-carbonate solution to form at least one mixture comprising both a liquid and solid phase while maintaining the pH of the liquid phase at from greater than 7 to less than 10, the exposing dissolving at least a portion of the uranium of the uranium comprising material into the liquid phase;
- separating the liquid phase from the solid phase;
- and
- processing the liquid phase to acquire the molybdenum.
