This study presents an analysis of the ARIANE GU3 sample, in terms of nuclide inventory, as well as sample rod and assembly decay heat. The validation of a number of CASMO5 and library versions are performed with regards to the measured nuclide inventory, taking into account two dimensional lattice simulations. Uncertainties due to various sources (nuclear data, operating conditions and manufacturing tolerances) are also provided, and are combined with biases into expanded uncertainties. This study is similar to a previous one on the GU1 sample and fit in the framework of code validation, as well as in the estimation of code predictive power for spent fuel characterization.

“…The effective fission yields of the Nd and Cs isotope monitors were calculated from the fission yields for each of the fissioning isotopes weighted according to their contribution to the fission. 3,16) The fraction yield for each isotope monitor used the data in the ENDF/B-VI file. 22) The concentration of the fissionable isotopes required for the calculation was determined by the IDMS and the nuclear data were obtained from Refs.…”

“…Among the various available techniques [2,3], chemical methods [4,5] involving dissolution of the irradiated fuel sample, followed by laboratory analysis were demonstrated to provide precise information on the extent of burnup and hence are prescribed by ASTM [1]. The chemical dissolution method is based on measurement of fission product monitor and the residual heavy atoms (actinides) in the sample of the irradiated fuel and is shown to be uniquely suitable as it does not require the analytical history of the unirradiated fuel.…”
