UO2SO4 in H20

  1. Jul 26, 2010 #1
    Does anyone have a suggestion for learning about the pH of UO2SO4 in H2O?

    Can one find the solubility constant for uranyl sulphate?

    This is really a chemistry question.

    The question stems from the design of a LEU subcritical aqueous reactor. I am under the impression that keeping the pH low is necessary in order to avoid precipitates of uranium. Does anyone recommend a good source for learning about the chemistry in aqueous reactors?

    Such sources are probably quite old, but nevertheless accurate. I've used uranyl nitrate solutions in the past. Uranyl nitrate hexahydrate is a precursor to ADU, which is precipitate in ammonium hydroxide IIRC. ADU is ultimately calcined to UO2.
