Challenge
Rapid and effective response to nuclear and radiological events demands detailed analysis of vast and varied data, from radiation detectors and environmental sensors to intelligence reports and simulation outputs. Today, the NNSA Nuclear Emergency Support Teams (NEST) relies on manual review and static artificial intelligence (AI) models that cannot sufficiently adapt as new data streams in, creating delays in detection, assessment, and response. This leaves decision-makers without real-time situational awareness or clear risk metrics during threat assessment and event response.
AI Solution
The solution will deploy a continuously learning, multimodal AI fusion system that integrates radiation and environmental sensors, simulations, and intelligence reporting to deliver real-time decision support with scenario modeling and uncertainty-aware risk metrics on crisis timelines for nuclear threats. The system will include four capabilities to make it operational without sacrificing reliability: (i) cross-cutting data governance for secure, standardized data pipelines; (ii) AI-enhanced decision support for adaptive threat-mapping tools and operator dashboards; (iii) scalable AI agents for semi-autonomous drones and robotics to survey, sample, and report from contested areas; and (iv) real-time risk assessment models to process large datasets into automated visualizations and risk scores for nuclear sites.
Justification
NNSA brings unique nuclear science expertise, secure facilities, and high-performance computing resources, and it embeds physics-informed models for transparent, auditable AI in mission-critical environments. Deploying a continuously learning fusion system will replace brittle, hand-tuned workflows with a single, scalable solution that reduces development time and cost while leveraging existing archives and platforms for rapid deployment and scaling.
National Impact
The initiative will shrink detection-to-response times from days to hours, enhance public safety and national security, and improve decision confidence while reducing false alarms through clear, quantified risk assessments. It strengthens deterrence by embedding AI into critical decision loops and supporting interagency coordination, delivers cost-efficient capabilities that can be adapted by civilian emergency responders and international partners. Use of this data fusion system in training scenarios will build NNSA’s capacity to identify signal through the noise during the most critical incidents.
