Standard Practice for The Ion Exchange Separation of Uranium and Plutonium Prior to Isotopic Analysis

Importancia y uso:

5.1 Uranium and plutonium are used in nuclear reactor fuel and must be analyzed to ensure that they meet certain criteria for isotopic composition as described in Specifications C833 and C1008. This practice is used to chemically separate the same mass peak interferences (isobaric interferences) from uranium and plutonium and from other impurities prior to isotopic abundance determination by thermal ionization mass spectrometry.

5.2 In those facilities where perchloric acid use is tolerated, the separation in Test Method C698 may be used prior to isotopic abundance determination. Uranium and plutonium concentrations as well as isotopic abundances using thermal ionization mass spectrometry can be determined using this separation and following Test Method C1625, C1672, or C1832.
