ISOTOPIC CORRELATION SAFEGUARDS TECHNIQUES: PROPERTIES OF CHEMICAL REPROCESSING PLANT MEASUREMENTS RELATING TO BURNUP

Data resulting from analytical measurements on representative samples of dissolution batches of spent reactor fuels at a chemical reprocessing plant have been evaluated employing techniques used in the past with burnup data. It was determined that burnup relationships between the depletion and growth of uranium and plutonium isotopes were readily evident from chemical plant data. This result is of importance since the measured batch data thus evidence a property termed as data consistency. Various evaluation techniques based on this result were applied to the measured batch data and it was seen that information pertaining to evaluation of data consistency was obtained.
