    Abstract

    Cross-section adjustment by integral measurements in fission-reactor assemblies affects cross sections in the energy range around the peak of the fission spectrum and below. For fusion-based systems, the important energy range is much higher (up to 15 MeV). Pulsed-sphere experiments were analyzed in view of their potential use as integral data by which the relevant cross sections in the latter energy range could be adjusted. These analyses were carried out by means of Monte Carlo calculations. The differential operator approach was applied to the calculation of sensitivities. The Monte Carlo code MCNP was modified to facilitate this approach.
