C-018 LETF
The C-018 LETF is planned to treat the evaporator overhead liquids. The
primary waste in the overheads is ammonia plus residues of_organics. The LETF
facility will be designed to stabilize the ammonia as ammonium sulfate using
sulfuric acid to neutralize it and destroy the organics chemically (ozone,
ultraviolet). The ammonium sulfate will likely contain a slight trace of
radioactivity (tritium and volatile radionuclides) plus some trace chemicals
making it a ca ndidate mixed waste material. A representative surrogate waste
mixture is giv en below:
C-018 LETF:
Soecie or MaterialOverall Content
Ammonium Ion 26%

Nitratel.2%
Silicon0.6%
Chromium VI 0.07%
Fluoride 0.05%
Copper II 0.02%
Cerium 0.02% ( transuranic stand-in)

The materials were weighed in the dry form milled to -20 mesh, and blended.
---------f,ummerc;al- grade fertilizer was used for the basic ammonium sulfate material.
