Abstract
A complex method of performing non-destructive measurements of the isotopic composition and mass of plutonium that does not require external data on 242Pu content is described. The method includes a set of measurements performed by means of γ-spectrometry, calorimetry, and neutron multiplicity. Determinations of the metrological characteristics showed that in terms of accuracy it greatly surpasses the existing analogues, approaching the coulometric and isotopic dilution methods. The method is recommended for use in the industrial production of mixed uranium-plutonium fuel.
