Multi-Informatics for Nuclear Operations Scenarios (MINOS)

• Nuclear Operations Scenarios: • Monitoring nuclear reactors for proliferation detection• Are reactors being used to divert special nuclear material?

• Multi-Informatics: multiple information sources• Different detectors and sensors

Motivation: Policy

• Non-proliferation Treaty (NPT)• Signed 1968, entered into force 1970

Weapons States

• US

• UK

• France

• Russia

• China

Non-nuclear Weapons States (185 states)• Cannot stockpile nuclear

weapons• Allow safeguarding by

the International Atomic Energy Agency (IAEA)

Non-signatories

• Oak Ridge National Laboratory High Flux Isotope Reactor (HFIR) and Radiochemical Engineering Development Center (REDC) research reactor and reprocessing facility

• Data collectors and data analytics teams• Data fusion: use multiple different data modalities to make, confirm and correlate

findings• External monitoring: sensors placed outside the facility

Data Analysis Method


FY18 Accomplishments• Focus areas:

• Reactor startup and shut down

• Familiarity with each individual data modality• Data organization: time-aligned data modalities

FY19 Goals• Focus areas:

• Transfer of targets to and from the processing facility• Reactor startup and shut down

• Data fusion analysis• Radiation data: more radiation detection nodes


Questions• Accounting for background?• Working with 10 months of data?• Looking for LANL summer students! Email [email protected]


CVT Impact• Los Alamos National Laboratory internship:

James Miller

• Personnel transitions: Post-bachelors’ position

• Technology transitions– IAEA– 9 national laboratories
