The sensitivity and uncertainty of various core burnup performance quantities (e.g., k[sub eff], burnup reactivity swing, local power density, etc.) to the heavy isotope fission spectrum parameters was investigated using depletion perturbation methods and ENDF/B-V covariance data. A brief description of the methods is followed by results of a 900-MW(thermal) fast reactor. The analysis here indicates that for a 900-MW(thermal) heterogeneous fast reactor, the experimental error in the ENDF/B-V fission spectrum parameters does not have a major impact on calculational uncertainty in the core burnup performance.
