Paul Wilson, Meghan McGarryU. Wisconsin-MadisonCVT Annual MeetingOctober 15-16, 2015

Consortium for Verification Technology Workshop: Oct 15-16. 2015

FY15 Status Update

2

● Focus on proof-of-principle● Toy problems to demonstrate underlying capability● Basis for expanding collaborations across CVT● Three primary examples

○ Behavior modeling for undeclared activities○ Simulated signal time series for anomaly detection○ Spatiotemporal metrics for fuel cycle monitoring


Facility Behavior Models for Material Diversion

3

EnrichmentFacility

Light Water Reactor Fleet

Undeclared Consumer

LEU

Natural U

● Demonstration with enrichment facility○ Willing to supply HEU when requested○ Operating near technical capacity○ Disrupts flow of LEU

Natural Uranium Source

HEU


Facility Behavior Models for Material Diversion

4

● Light water reactor fleet requests randomly fluctuating, Normally distributed quantities

● Varying request behaviors for HEU consumer

● Assume supplied LEU throughput is declared signal


Simulated Data Streams for Anomaly Detection● Simple approaches are possible for signal processing

5


Spatiotemporal Models for Fuel Cycle Monitoring

6

● Some signals are detected in environment at a distance○ Effluents & emissions○ Transportation patterns

● Superposition of signals from different sources● Requires

○ Location of facilities in space○ Model for signal propagation○ Method to superpose signals from multiple facilities

FY16 - Improved Facility Modeling

9

● Develop more complex models of agent behavior○ Review historical record○ Mechanisms for responding to external stimuli to

behavior■ Inspections■ Detection

● Compare multi-mode signals and signatures from multi-national facilities with those from national facilities


FY16 - Integrating Across Thrusts

10


FY16 - Integrating Across Thrusts

11

● Thrust 1: (Glaser) - Nuclear Archeology - FMCT○ Reduce uncertainty in fissile material inventories from

(newly) released facility operation histories● Thrust 2: (Hero) - Data Analysis Techniques

○ Add range of “signals” from facility operation○ Generate coordinated time series of mixed mode signals

● Thrust 3: (???) - Virtual testing of safeguards○ Provide realistic source spectra from facility processes in

transition● Thrust 6:

○ Develop simulations for use in courses
