Dumrose, A C

Uranium-loaded graphite fines. mostiy -100 mesh, are incinerated by simultaneous impingement of several oxygen streams on the surface of the dry charge in a cylindrical, water-jacketed, stainless steel burning chamber with an 8 in. ID. The oxygen distribution head automatically follows the falling surface of the burniiig graphite as the charge is consumed. Combustion rates of better than 3 lb per hour of powder are attained. The residue from incineration is leached with nitric acid. Uranium peroxide is precipitated directly from the resulting nitrate solution. Two successive precipitations produce preduct of good purity without a preliminary solvent extraction of the leach solution. (auth)
