Challenge
Effective deterrence depends on credible accountability. Every nuclear material has a signature, and through a combination of radiation measurements and material characterization, the provenance of nuclear materials and detonated nuclear device designs can be determined.
Attributing nuclear materials either outside of controlled environments or following a nuclear detonation of unknown origin to their source through forensic attribution will enable the credible commitment of American retaliation. This effort will dramatically improve the speed and accuracy of nuclear forensic assessments by leveraging AI-enabled workflows, data integration, and physics-based machine learning, thereby enhancing United States deterrence against potential nuclear threats.
AI Solution
The solution will further develop and use AI tools to rapidly characterize samples of special nuclear material and post-detonation nuclear debris, infer likely process history, and support device and material reconstruction. The Rapid Quantification of Nuclear Forensic Morphological Signatures focus area will use AI models to quickly analyze morphological features of nuclear materials, increase the speed and accuracy of signature interpretation, and improve understanding of material processing histories for effective nuclear forensics. The In-field Measurements of Nuclear Detonation Debris focus area will adapt AI tools for rapid quantification of nuclear debris in post-detonation scenarios, enabling real-time field analysis that significantly reduces debris diagnostic timelines. The Advances in Post-Detonation Device Reconstruction Modeling focus area will leverage AI, advanced simulations, and intelligent data interpretation to accelerate device reconstruction following a nuclear detonation and provide timely, actionable insights to decision-makers even in the early stages of an incident.
Justification
The project capitalizes on NNSA's unique resources and expertise to enhance the speed and accuracy of nuclear threat attribution. It builds on NNSA's combination of nuclear weapons design history, state-of-the-art laboratory capabilities, and subject matter experts; minimizes current bottlenecks in sample processing and reporting for more efficient use of existing resources; directly supports the deterrence of nuclear threats by enabling fast, credible attribution; and leverages existing infrastructure investment for rapid implementation without compromising quality.
National Impact
This initiative will significantly enhance national security and emergency response by accelerating threat assessment processes and shrinking the timeline from material collection to attribution, thereby accelerating policy and response decisions. It reinforces deterrence by showing adversaries that misuse of nuclear materials will be attributed swiftly, leading to decisive American retribution; improves the ability to quickly assess nuclear incidents and preserve public safety through real-time analysis; and creates AI-based forensic methods that can be adapted to other critical security and industrial domains.
