Exponential Experiment with a Thorium-Uranium Fuel in Graphite
- North American Aviation, Inc., Canoga Park, CA (United States). Atomics International Div.
An exponential experiment with multirod fuel elements in graphite moderator is described. The fuel is a thorium-uranium alloy. The buckling, thermal utilization, and resonance escape probability for one lattice configuration have been measured. In the analysis, emphasis is placed on determining the effective resonance integral of the fuel element. From the measured resonance escape probability, 0.856 ± 0.008, an integral (including 1/v capture) of 9.7 ± 0.8 barns is obtained. From the measured buckling (10.89 ± 0.05 m-2) and thermal utilization (0.9445 ± 0.0009) a value of 11 ± 2 barns is obtained for the integral. Although in agreement with one another, these values are not in general agreement with either calculated values or the results inferred from other measurements.
