How nuclear security can help bring the US and China together on AI

Bulletin of the Atomic Scientists | Stephen Herzog

The United States and China face mounting threats from artificial intelligence capabilities that allow malicious actors to identify vulnerabilities in nuclear facilities and orchestrate physical attacks. Washington and Beijing could counter these shared risks by establishing a six-month pilot agreement to test AI applications for defending civilian nuclear infrastructure.

Escalating geopolitical rivalry previously stalled official lab-to-lab nuclear security dialogues established in 2016. However, rising power demands from AI data centers—driving private backing for small modular reactors like Kairos Power and X-energy—create shared economic stakes in facility protection. Bilateral technical exchanges using simulated data from fictional sites offer a practical mechanism to test integrated threat detection across live surveillance, access logs, and operating records. This approach exposes a central strategic trade-off: balancing cooperative risk reduction against the danger of disclosing sensitive defensive methodology to a geopolitical competitor. Intelligence risks remain significant. Ultimately, successful joint testing could establish baseline confidence for broader governance of military artificial intelligence.

Comment

Bilateral lab-to-lab frameworks for artificial intelligence governance expose an unavoidable strategic trade-off between operational risk reduction and counter-intelligence exposure. Participating entities like Sandia National Laboratories and the China Atomic Energy Authority cannot benchmark defensive AI threat detection without revealing the specific data structures and operational thresholds that define nuclear site security. Sharing baseline anomaly detection parameters across digital twins creates an unavoidable friction point between validating algorithmic safeguards and shielding proprietary vulnerability maps from foreign intelligence collection.

The mechanics of synthetic data gating illustrate how this operational tension operates in practice. By substituting actual reactor telemetry with simulated operational environments, technical teams attempt to isolate algorithmic logic from true facility baselines. Yet, even sanitised model outputs reveal how an algorithm weighs concurrent sensor disruptions against access logs. Consequently, evaluating threat-detection models developed by private entities like Anthropic requires exposing underlying model parameters to adversary probing during joint benchmarking exercises.

Strategic Question for Discussion

If Sandia National Laboratories and the China Atomic Energy Authority utilise synthetic operational data to protect actual plant architecture, does synthetic model validation provide sufficient confidence to deploy defensive AI systems, or does it leave unmonitored blind spots in physical perimeter protection?

Synthetic data validation reduces immediate intelligence exposure, but the available evidence points toward persistent gaps when translating simulated threat environments into actual nuclear facilities. My assessment is that while synthetic benchmarks allow basic algorithmic alignment between foreign laboratories, real-world operational variations will ultimately force participating institutions to choose between accepting unvalidated deployment risks or sharing authentic facility telemetries.
