Introduction • Post-detonation nuclear forensics is a critical tool • Pre-detonation nuclear forensics is under-utilized as a technological capability “Although the focus of today’s hearing is nuclear forensics and attribution, I must reiterate that our number one priority is to keep fissile materials – plutonium or highly enriched uranium – out of the hands of terrorists.” ~ Dr. Steven Aoki, Dep. Undersecretary for Counterterrorism, House subcommittee hearing, Oct 10, 2007.

• International collaboration can and should be utilized to strengthen nuclear forensics and its application

Advantages of Pre-Det approach • A simpler problem to solve • Time is less critical • Provides concrete demonstrations, recommendations and exercises • Builds critical database and capabilities for future applications • Entire spectrum of response is available

Nuclear Attribution Interdiction/ Detonation

• Characterization – Scientific methods (experiments) – Physical, chemical, and isotopic.

• Forensics – “Known” signatures • Characteristics that distinguish one material from another. • Comparative samples • Predictive models – Source, Processes, and Route

• Attribution – Intelligence – Nuclear Forensics – Traditional Forensics

Build on existing infrastructure to centralize non-sensitive forensics data at IAEA. Regime of participating states agree to: – – – – – –



Create a Forensics Management Team (FMT) Nuclear forensics laboratory qualification through ITWG. Share results of non-sensitive forensics data. Produce capability of self-attributing sensitive materials. Interdiction and pre-detonation protocols overseen by ITWG. Participate in international attribution board reporting to the IAEA board of governors.

BUILDING INTERNATIONAL CAPABILITY • Nuclear materials databases in progress – Under development (mostly commercial fuels) – US, Russia, Europe (JRC), and IAEA

• Partial participation still helpful – Exclusion is a useful result – 87% of fissile material controlled by US/Russia (Albright 2005) – Involuntary or historic sampling conceivable

• Challenges to sample collection, analysis and verification – Standards & Protocols – International Technical Working Group (ITWG)

International Cooperation Yellowcake

• Evaluating risks and benefits for sharing information. – U.S. – Others • Preparing to share information, need based disclosure • Establishing credibility of methods internationally • Resolving real-world cases and conclusions

Conclusion • Nuclear Forensics is a difficult but important problem. • Pre-detonation forensics provides an opportunity for measureable, actionable prevention of unattributed nuclear detonations by identifying high risk sources. • Expanding international capability and cooperation in nuclear forensics will strengthen international security.
