Abstract: | Isotopic dilution mass spectrometry has been applied to assess the plutonium concentration in samples such as those obtained
from the dissolution of irradiated uranium fuels in a reprocessing plant. Prior to the analysis, plutonium is taken through
a redox cycle and is separated from uranium and fission products by extraction into TTA-xylene. The extraction procedure,
the standardization of the spike solution and the mass assay of the plutonium are described; typical results under plant conditions
are given. The overall precision of a single measurement of the plutonium concentration is 0.6%, expressed as relative standard
deviation, including the plant sampling error, dilution error and analytical error. |
