The Purdue Fast Breeder Blanket Facility (FBBF) is a source-driven facility which simulates the neutron environment of a fast reactor blanket, allowing calculation-to-experiment (C/E) comparison to be performed on an absolute basis, Fission rates for /sup 239/Pu, /sup 235/U, /sup 237/Np, /sup 238/U, and /sup 232/Th were measured and compared to standard diffusion calculations to provide an improved description and understanding of the high energy neutron fluxes and reaction rate distributions in the FBBF blanket. Fused quartz track recorders were irradiated with fission foils, and automatically analyzed by an image processing system, with a especially developed software, to obtain absolute specific fission rates. The measurements were used as tests of standard two-dimensional diffusion calculations performed with the codes 1DX and 2DB, and the nuclear library LIB-IV.
