Abstract

An automatic system for the determination of the stable oxidation states of uranium and plutonium, and nitric acid in nuclear fuel reprocessing streams has been developed. The system based on a spectrophotometry is capable of rapidly determining U(IV), U(VI), Pu(III), Pu(IV) and Pu(VI). The spectrum obtained from a mixed solution is separated into individual spectra of several components with graphical operations. Acidic concentration can also be obtained from the ratio of specific peaks in a spectrum of U(IV), U(VI), Pu(III) or Pu(IV).
