Abstract
A general approach to sensitivity studies is introduced using a quanti-
tative definition of cross-section sensitivity. The definition offered is
intended to be both practical and physically meaningful. Its advantages in
comparison with other approaches is discussed and its use in analysis is
illustrated for a sodium-iron transport problem. Results of the analysis
include-a discussion of the role of important total cross-section minima
in deep penetration in sodium and iron and the importance of certain energy
ranges and partial cross sections for the sodium-iron system. The predictive
aspect of the approach is demonstrated in comparisons of rigorous and predicted
results for small cross-section perturbations and in conclusions about the
order of Legendre expansion of the scattering kernel.1
