Summary of Experience with the Use of Isotopic Correlation Safeguard Techniques,
Abstract
Isotopic correlation safeguard techniques which have been developed to verify Pu/U ratio values are derived from burnup relationships in spent fuel data measured at the input to a chemical reprocessing plant. Relationships have been observed from all the chemical reprocessing plant isotopic data received to date at BNW and thus isotopic correlations have been applied successfully to these data. Because the physical laws governing the irradiation of nuclear fuels are immutable, isotopic relationships are a common characteristic of all spent fuels from any given reactor. It remains to be seen what the characteristics of some of the relationships will be for reactor types not yet studied and for newer fuel designs in reactors already investigated. There is, however, little doubt that relationships will be evident for all reactor fuels which will be appropriate for verifying the Pu/U ratio at the reprocessing plant input. (Author)
