Underwater measurement of a 15 times 15 MOX PWR (mixed oxide pressurized water reactor)-type fuel assembly

Abstract

Underwater measurements have been made on a fresh, mixed oxide, 15 {times} 15 fuel assembly to evaluate various nondestructive assay techniques for determining the plutonium content in the assembly. For these laboratory measurements, best results were obtained with assays using multiplication-corrected neutron coincidence count rates.
