Once you've separated it out, you could try offering it to any friends who
make decorative glass. It gives a wonderfull fluorescent yellow color (if
you like that sort of thing).

Subject: Re: RE: uranium nitrate disposal
Mr. M.Kirby at S.A.I.M.R in Johannesburg, South Africa asks:
>>Uranium nitrate in solution. How do you guys dispose of the stuff?
Incineration? Encapsulation?
I've got 20 litre drums of the stuff sitting in my waste store and would
appreciate any advice.<<
Uranyl ion can be precipitated out, very nearly quantitatively, as sodium
uranyl sulfate, a dense granular bright yellow precipitate easily separated
out and stored in an airtight jar. I suppose you have some idea of the
initial concentration of the solutions. From then on it's a straightforward
stoichiometric calculation of how much sodium sulfate (or sodium hydroxide
and sulfuric acid) you need. - In the United States I doubt you could find
anyone in a hospital who could do the calculation, and - if I didn't do it
myself - I would enlist the aid of a bright high school chemistry student.
Obviously incineration would only disperse the stuff, since you're disposing
of a chemical element.
