Scale-up of the SY-102 remediation flowsheet

An anion exchange unit operation for the removal of actinides from a high nitrate-low acid solution has been successfully scaled-up more than one order of magnitude. The behavior of the scaled-up system was similar in many ways to the previous small scale experiments. It is characterized by a slow approach to equilibrium, displacement of Am by the other actinides, and improved column performance with increasing column length. The breakthrough of Americium, the most weakly sorbed actinide of those present, was predicted for the larger system with reasonable accuracy
