Uranium Pyrophoricity

["Mike Barringer" <mike_barringer@fernald.gov>]

     Recently a message giving reference sources on plutonium pyrophoricity 
     appeared on the bulletin board.  Can anyone supply references on 
     uranium pyrophoricity?  The physical form of the uranium will be as 
     small pieces and foils, potentially with small quantities of iron 
     present.  Please respond directly to me at mike_barringer@fernald.gov 
     or via the bulletin board.
     
     Thanks
