CONTENTS
CHEMICAL RESEARCH
ACTINIDE RECOVERY AND RECYCLE PREPARATION FOR
WASTE STREAMS ................... .......... 1
A program was initiated to determine the feasibility
of removing actinides from secondary aqueous waste
streams likely to be produced during reactor fuel
fabrication and reprocessing. Evaluation of actinide
recovery methods for the salt waste and wastewater
streams and of recycle preparation problems is the
major emphasis of this program. (ORNL Subcontract)
SLUDGE REMOVAL FROM RASCHIG RING FILLED TANKS .... ........... 3
Solvents were evaluated for removing sludge from Raschig
ring filled tanks used for plutonium processing solutions
and lathe coolant oil. (DDS Endeavor 333*)
REMOVAL OF LEAD FROM AMERICIUM PRODUCT ...... ...... ...... 4
Several process methods were tested to evaluate their
ability to effect removal of lead contaminant from
americium product. (DDS Endeavor 113)
CALORIMETRY AND THERMODYNAMICS OF NUCLEAR MATERIALS ............ 6
Thermodynamic properties of plutonium metal and the
plutonium-hydrogen system are being investigated. A
compilation of the thermodynamic properties of all
actinide materials is also underway. (DDS Endeavor 112)
SECONDARY AMERICIUM RECOVERY ....... . .......... ..... 7
Amber!ite XAD-4 macroreticular sorbent was tested for
use in an extraction chromatography process to remove
americium from acidic process waste streams. (DDS
Endeavor 333)
