Tests of a customer defined (Bechtel Marine Propulsion Corporation, West Mifflin, PA)
plutonium water treatment system were conducted at the Idaho National Laboratory (INL).
These tests were designed to give insight into how plutonium interacts with three readily
available ion-exchange media. The solutions prepared during these tests were not homogeneous
and probably consist of particulate and colloidal species as well as soluble species.
The overall results of these tests demonstrated that plutonium contamination from an oxide form
dissolved or suspended in water, while a difficult problem, can be dealt with using the common
media. Results from the "bench scale" KD and dynamic flow tests were very consistent and
showed that the highest removal efficiency was achieved from the DT-30 (94%) with the IRN-
150 next (89%) and with the lowest efficiency with IRC-748 (57%). The "pilot scale" tests
showed that the IRN-150 (first column) had even higher efficiency with >99% removal (virtually
100%) in each of the 3 flow regimes; this was consistent with the results of the "bench scale"
tests. The "pilot scale" tests also showed that the IRC-748 was less effective, but at 80% overall
effectiveness, it was substantially higher than the "bench scale" tests.
