Description

  • Content Description: A previous laboratory study indicated that Pu and Am in the waste discharged to the crib would not be sorbed on the sediment but migrate with the waste solution. Field study of the TRU distribution beneath the crib support the conclusions of the laboratory study. The current laboratory study indicates that waste-sediment interactions have altered the waste, resulting in the retention of almost all of the Pu and most of the Am on the sediment tested. Batch leaching study results, in agreement with results of an earlier study, show Am concentrations are determined by an Am compound having pH dependent solubility. Batch studies also show that Pu is not present in the sediment sample as PuO/sub 2/. The mechanism of Pu solution is ion exchange desorption. The solubility of TRU can be enhanced under column leaching conditions which favor concentration of complexing agents at the wetting front. Plausible environmental leaching conditions might be expected to mobilize less than 1% of the Pu present in the sediment and approximately 30% of the Am.
