Global Nuclear Security

Both DOE and the National Nuclear Security Administration are working to reduce the risk of nuclear proliferation and provide technologies to improve nuclear safeguards. The detection and identification of actinides during reprocessing enhances safeguards by making material tracking less intrusive and more transparent. A laser-induced breakdown spectroscopy (LIBS) system for rapid, real-time elemental analysis of actinides in molten salts and mixtures of radioactive metals from dried solutions was developed under an LDRD. Such analyses can improve detection of illicit reprocessing activities.
