Sensitivity coefficients for the nuclear data of the principal constituents of a representative /sup 233/U-/sup 232/Th fueled LMFBR have been generated. Generalized perturbation coefficients for several reactor parameters were computed with the VARI code and ENDF/B Version 4 data for a homogeneous one-dimensional spherical model. The following ten reactor parameters were studied: eigenvalue; breeding ratio; inner core conversion ratio; outer core conversion ratio; central reaction rate ratios of f/sup 02/, c/sup 23/, and c/sup 02/ relative to f/sup 23/; and the central material reactivity worths of /sup 233/U, /sup 232/Th, and /sup 23/Na. Total (energy-integrated) and energy-dependent sensitivity coefficients were obtained for each of these parameters to each of the following nuclear data: sigma/sub f/ for /sup 233/U, /sup 234/U, /sup 232/Th, and /sup 233/Pa; sigma/sub c/ for /sup 233/U, /sup 234/U, /sup 232/Th, /sup 233/Pa, /sup 23/Na, SS316, and fission products; anti ..nu.. for /sup 233/U and /sup 232/Th; and sigma/sub inel/ for /sup 232/Th. These data are combined with estimated data uncertainties and with observed large differences in recent data evaluations to project the impact on integral parameters calculated for a /sup 233/U-/sup 232/Th fueled LMFBR.
