This paper reviews the current status of measured integral data for fission-product fast-neutron capture and the application of those integral measurements for cross-section testing. The various types of integral experiments are described and an assessment is made of the utility of the measured data for testing cross sections. Although the integral data base is surveyed as completely as possible, specific emphasis is given to those integral data which have been published since the 1979 Bologna specialist's meeting on fission-product nuclei. As a second thrust of this paper, the utilization of measured integral data for cross-section adjustment and for conventional C/E testing is discussed. Specifically, the role of measured integral data for the ENDF/B-V evaluation of fission-product capture cross sections is addressed. A detailed discussion is presented of a study made to assess the consistency of the ENDF/B-V cross sections and the measured integral data from experiments in the Coupled Fast Reactivity Measurements Facility (CFRMF) and in the Experimental Breeder Reactor-II (ERB-II). We conclude the paper with a summary of the outstanding integral test discrepancies and point out the areas for improving consistency between integral data and evaluated cross sections.
