Fission rates and /sup 238/U capture rates for loading 1 of the Fast Breeder Blanket Facility

Technical Report ·
OSTI ID:5487849

Fission rate and /sup 238/U capture rate measurements have been completed for the first blanket loading (FBBF-1) of the Fast Breeder Blanket Facility. Fission rates of /sup 232/Th, /sup 235/U, /sup 237/Np, /sup 238/U, and /sup 239/Pu were measured using fission track recorders. A Ge(Li) counting system was used for the /sup 238/U capture rate measurements; this system has been compared with a similar system in use at Argonne National Laboratory. The measurements have been closely compared with diffusion and Monte Carlo calculations. Because FBBF-1 was subcritical and driven by isotopic neutron sources, the measurements and calculations have been compared on an absolute basis.
