N2 - STARBUCS is the SCALE sequence dedicated to criticality safety analyses employing burnup credit. STARBUCS enables simulation of important burnup credit phenomena, and its input options allow analysts or reviewers to investigate the impact on criticality safety of various assumptions related to the burnup credit calculation methodology for spent nuclear fuel in transport or storage cash. Options are provided to model the axial and radial burnup variations within a spent fuel assembly, to select the actinide and fission product nuclides to be included in spent fuel compositions, and to adjust the predicted inventories to account for isotopic composition bias and bias uncertainty. Sequence enhancements available with the SCALE 6 release include the capability to perform a burnup loading curve search and the ability to use continuous-energy Monte Carlo criticality calculations. This paper presents a review of the STARBUCS features available in SCALE 6, STARBUCS applications that illustrate the impact of various modeling assumptions on burnup loading curves, and a comparison between STARBUCS calculations using SCALE multi-group and continuous energy cross-section libraries in terms of computer time and keff results for various spent fuel configurations.
