Chambers, S; Hughes, T -G

The solution of plutonium nitrate, separated by extraction with dibutyl glycol from the solution of fuel elements, is concentrated by evaporation and purified by extraction with a mixture of tributyl Phosphate and kerosene. The residual impurities coming from the rengents and the apparatus can be eliminated by a second purification in glass apparatus. The nitratc solution is concentratcd. The nitrate is transformed to the oxide, then to the fluoride, and finally to the metal by Ca or Mg reduction. The impurities, which represent less than 1% by weight, are iron, nickel, chromium, and uranium. The construction of an installation for this process is briefly described. (tr-auth)
