Target Audience

Individuals that perform, manage, or supervise neutron based nondestructive assay (NDA) techniques. Auditors, regulators, and policy makers may also benefit from attending this course.


To provide the participant with in-depth knowledge of the major neutron NDA techniques used domestically for MC&A measurements of bulk special nuclear material (SNM) and in international safeguards.


  • Fundamental principles of neutron detection
  • Passive neutron coincidence counting of bulk plutonium
  • Multiplicity counting of bulk plutonium
  • Active Neutron Coincidence Counting of bulk uranium and fresh fuel assemblies.
  • Waste characterization using neutron counting.

NDA Equipment Covered: NMC, AWCC, UNCL, Add-a-source
