Spectral synthesis methods, in which the neutron flux spectrum is synthesized from known trial spectra, is applied to fast-reactor dynamics. Numerical results demonstrate that important spectral shift effects which occur during transients are adequately represented by synthesis models with two trial spectra. Conventional few-group models which require equivalent computational effort are found to provide a significantly inferior representation of these effects.
