Evaluated Lumped Fission Product Cross Sections for Fast Reactor Analysis - Based on ENDF/B-V Data. Both one-lump and two-lump models have been investigated in detail. Fission product inventories at various burnup steps were calculated by the EPRI-CINDER-2 code and used as weighting functions for lumping.
