Description: This course is an introduction to non-destructive assay (NDA) measurement techniques that may be used for nuclear material accountancy by the International Atomic Energy Agency (IAEA) or within a State’s System of Accounting and Control (SSAC). The course is designed to teach students the fundamentals of gamma-ray detection and provide an introduction to neutron detection. The course will explore the application of NDA measurements techniques typically used for international safeguards. Students will also receive a refresher on the nuclear fuel cycle and learn about the basics of nuclear material accountancy, including IAEA sampling plans and material balance evaluations.
The course will comprise general safeguards presentations and detailed training on specific NDA measurement techniques. A number of hands on laboratory exercises will be featured using Los Alamos National Laboratory’s training facility and leveraging the exemplary expertise and resources that are also used to instruct IAEA inspectors in NDA principles each year. This course will allow participants a unique opportunity to perform NDA measurements using assay systems—such as sodium iodide systems, high-purity germanium detectors, and a variety of neutron-based detectors—on a variety of relevant nuclear materials. The course will conclude with discussion of good practices and the appropriate application of NDA measurements to meet a State’s international safeguards needs.
