Uranium Turnings




We have some Depleted Uranium metal turnings that are contaminated
with lead and beryllium.  These metal turnings are also pyrophoric.  The
RCRA treatment for metals and for pyrophoric materials that we intend to
use is encapsulation.  

We have a recipe for concrete encapsulation of depleted uranium
powder; however, we do not have a recipe for uranium turnings.  Does
anyone have such a recipe, or know where one is available for
encapsulation of this type of material to meet the land disposal
restrictions and allow for disposal?  Can the recipe for the powder be
used for the turnings?
