摘要：

Fission rate measurements were performed in the Purdue Fast Breeder Blanket Facility (FBBF) and compared with two-dimensional 50-group diffusion calculations on an absolute basis. Fission rates in **2**3**9Pu, **2**3**5U, **2**3**7Np, **2**3**8U, and **2**3**2Th were measured using fused quartz fission track recorders. Calculations using the IDX and 2DB codes, and the LIB-IV nuclear data library were compared with the measurements in the form of reaction rate calculated-to-experiment (C/E) trajectories. The investigations were aimed at providing an improved understanding and description of the high-energy neutron fluxes and reaction rate distributions. Also investigated were previously reported C/E reaction rate discrepancies in the blanket.
