Abstract: | Correct prediction of the fission products inventory in irradiated nuclear fuels is essential for accurate estimation of fuel
burnup, establishing proper requirements for spent fuel transportation and storage, materials accountability and nuclear forensics.
Such prediction is impossible without accurate knowledge of neutron induced fission yields. The uncertainty of the fission
yields reported in the ENDF/B-VII.0 library is not uniform across all of the data and much of the improvement is desired for
certain fissioning isotopes and fission products. We discuss our measurements of cumulative fission yields in nuclear fuels
irradiated in thermal and fast reactor spectra using Inductively Coupled Plasma Mass Spectrometry. |
