The Office of Proliferation Detection (PD) develops capabilities to detect special nuclear materials and weapons production and movement, as well as for transparent nuclear reductions and monitoring.

The PD efforts are aligned along three functional areas:

• Nuclear Weaponization and Material Production Detection: Supports the development of technology to target the detection and characterization of foreign weapons program activities, including materials and weapons production.
• Nuclear Weapons and Material Security: Supports the development of nuclear security and nuclear arms control treaty monitoring and verification tools and applications, and supports operational interdiction and nuclear security efforts across NNSA.
• Nonproliferation Enabling Capabilities: Supports the development of novel, cross-cutting technologies like simulations, algorithms and modeling applicable to multiple NNSA and the interagency missions.
