About Us

The Safeguards Science and Technology Group develops and implements nuclear material measurement systems in support of national and international safeguards and nonproliferation policy objectives.

The work performed in the group has a major impact on preventing the proliferation of nuclear weapons by providing accurate measurement technologies for nuclear materials at domestic and international sites. Applications include nuclear materials control and accountability for domestic DOE and international nuclear facilities, nuclear waste disposal, nuclear material stabilization efforts, and international nonproliferation efforts. The group's research areas include: neutron and gamma-ray measurements (detector simulation, design, development, and evaluation), nuclear measurement techniques, neutron and gamma-ray tomography, portable spectroscopic analysis, imaging with neutrons and gamma-rays, accurate low-level heat measurement techniques, X-ray fluorescence and transmission, electronics and software development for remote monitoring, detection of clandestinely transported radioactive materials, and related activities.
