Abstract

The following calculations may assist in the detection of nuclear fuel reprocessing activities through 'environmental' measurements. As a result of reprocessing, fission products xenon and krypton are released into the atmosphere. They show a different isotopic composition compared with natural atmospheric xenon (krypton). The released fission xenon (krypton) is diluted in air, mixed with natural xenon (krypton) resulting in a change of isotopic composition. To ascertain whether it is possible to detect the small isotopic alterations in atmospheric xenon (krypton) calculations were performed based on the principles of isotope mixing as in isotope dilution. To provide an estimation of the isotopic alterations in atmospheric xenon (krypton), blending calculations were carried out using the isotopic compositions of atmospheric xenon (krypton) and calculated compositions of fission gases. The calculated ratios in the blend were compared to the ratios of natural xenon (krypton) as measured using highly developed, ultra-accurate measurement facilities isotopic mass spectrometry.
