A review of TR-14 based on an extraction rate of 66.6 l/hr is presented. The remarks on activity calculations at the beginning of TR-23, which is a supplement to TR-14. are valid for the discussions and calculations included in this revision Material balances are established for U and PU. (J.RD.) l6896 See also Technical Report Ho. 10 (NP-7667). A sunmary of recent developments in aqueous reprocessing of irradiated U is presented. General trends are discussed as well as recent work on dualtemperature scrub and extracting agents such as amines. In addition, a discussion of organic ion exchangers for Pu tail-end treatment is presented along with the use of inorganic ion exchangers such as silica gel and other hydrous oxides for Pu and U separations. Consideration is also given to substituting U(Nl for Fe(U) as a reducing agent for Pu(IV), and the possibility of decreasing the number of extraction cycles is examined. It is suggested that the dualtemperature scrub merits closer investigation as does waste recycling, anion exchange purification of Pu, and the use of amines as extracting agents. (J.R.D.)
