Measurement and analysis of reaction rates in simulated PFR demountable subassembly heat-pins in ZEBRA

Creators

Description

Measurements completed on the Zebra reactor to assess the reliability of current diffusion-theory predictions of the power generated in DMSA heater pins in PFR, are described. A range of heater pin configurations was simulated, and reaction rates of fission in Pu 239, U 238 and U 235 and capture in U 238 were measured. These were also calculated using standard Zebra methods. The calculated-to-experimental ratios were in the range 1.03 to 1.05, giving confidence in the methods of prediction used for PFR. (U.K.)
