An In-line Neutron Coincidence Counter for Plutonium Mass Quantification

摘要

Calorimetry is a time-consuming nondestructive assay for plutonium mass quantification in both person hours and sample measurement 1 and provides low uncertainties. Decreasing the time required for mass quantification of plutonium to similar levels of uncertainty as calorimetry through an alternative assay would increase the efficiency of plutonium purification operations.
