Gamma spectrometric determination of the isotopic decomposition of plutonium in containers using MGA and FRAM software

  • Published:
Atomic Energy Aims and scope

Plutonium dioxide is stored in special containers, holding about 3 kg plutonium each, in a dump at the RT-1 plant of the Industrial Association Mayak. The certificates on the containers with plutonium produced in 1990–2000 do not contain any data on the isotopic composition. Without removing the plutonium from a container, the isotopic composition can be determined only by γ-spectrometry. This paper compares the MGA and FRAM computer codes used to determine the isotopic composition of the plutonium when performing measurements on samples with a large mass.
