I I, IMTRODUCTIOB AND OBJECTIVES .-In the operation of countercurrent extraction columns, as in the Redox process, it is possible,and probable, that from unexpected behaviour of a column, operator error, colloZda& formation, etc., there will result from time to time excessive losses of uranium and plutonium f n the overall process. These losses w i l l naturally aqueous waste streams. If the.loss is excessively high, and such loss naterial can be recovered by some '. accumulate in the wa&e streams, particulartly in the additional method, then if economical and within reason, the recovered materials gan be returned to a ISF column f o r further proces8ing. The objegtive of this work has been to develop such a method to recover uranium and plutonium from such off-standard waste streams in a form whereby the uranium I .nd plutonium can be returned to the process line and subsequentlyaied and separated, Z~G w x % E D l i r r a~9 m DECtASSlRED 1 aYXUibrnW C G-M-2 11.
