Abstract

Measurement of the uranium content in liquid streams is important for criticality safety, process and quality control, and nuclear material accountability in nuclear fuel cycle facilities. Conventional analytical techniques such as spectrophotometry, passive gamma-ray spectroscopy, x-ray fluorescence, and densitometry are frequently unsuitable because they may be slow, require sample handling, or be subject to interference by high concentrations of fission products or neutron emitters in the solutions to be analyzed.
