The administrative organization of data and subject matter expertise
forms the framework for a national nuclear forensic library
Fundamental Requirement: Is it ours?
•
If nuclear material is found outside of administrative
controls anywhere in the world, then each country should
be able to answer the question:
“Is this consistent with our material?”
•
Verifying inventory may confirm that material does not
appear to be missing, but that may not be sufficient
•
A national nuclear forensic library is extremely valuable for
answering this question with timeliness and confidence
National Nuclear Forensics Library Model
•
NNFLs give countries the capability to identify materials
used, produced or stored within their borders
Requirements
Options for Success
•
National-level mandate
•
Defined query protocol
•
Organize necessary
resources
•
Government and
industrial material holders
•
Data
•
Subject matter expertise
•
Centralized or formally
federated databases
•
Formal effort to understand
useful material characteristics
•
Accompanying material
archive and analysis capability
What is needed to answer “is it ours?”
General Process for Building a NNFL
NNFL Effort and Complexity
•
The level of effort required to develop a library varies
greatly between countries
•
NNFL complexity is largely dictated by the nuclear
activities within a state
•
Not every country needs to capture the same material
characteristics to have a functional NNFL
Complexity of
NNFL and
Associated
Materials
Databases
•
Quantity of radioactive sources
•
Variety of radioactive sources
•
Quantity of nuclear materials
•
Variety of nuclear materials
•
Production or processing of
nuclear or radioactive materials
•
Research and development
activities
Practical Approach to Implementation
•
To date, guidance for developing a NNFL has not
adequately addressed variable complexity of
nuclear activities
•
Proposed approach
–
Evaluate nuclear activities to guide NNFL development
–
Adapt general guidance already available to
categories (e.g. draft IAEA guidance)
•
This approach should improve understanding
regarding the level of effort necessary to attain a
functional national nuclear forensics library
Nuclear Fuel Cycle Activities and Complexity
Increasing NNFL Complexity
IAEA Member States and Fuel Cycle Activities
For 219 IAEA Member States, developing a functional
NNFL should be a relatively easy task (Groups 1&2)
Group 1 & 2 Countries
•
Most countries fall into these two categories
•
National radioactive source registries may largely fill
these nations’ NNFL needs
–
Supplemental information may be necessary to uniquely identify
some sources
–
Additional information on reactor or non-accountable source
materials may need to be captured separately or as part of an
existing source registry
Group 1 & 2 NNFL
•
Regulator’s
licensing or
tracking system
likely has most of
the information
necessary for a
NNFL
•
Some additional
information might
be required for
non-sealed source
materials
•
Not all
recommended
characteristics may
be needed for all
libraries

Group 3, 4, & 5 Countries
•
NNFL’s are supported by source registries, nuclear
materials accountancy information, production data
•
Additional material characteristic information is required
to uniquely identify most materials
–
Analytical measurements and subject matter expert evaluation
necessary to identify distinguishing characteristics

Group 3, 4, & 5 Level of Effort
•
Substantial effort may be required to establish a
functional national nuclear forensic library
•
Large number of
material types
•
Understanding of
material flow through
fuel cycle
•
Statistical expertise for
identifying material
populations and
comparative analyses
•
Organizing available
data and subject
matter expertise
essential
Establishing an NNFL
Specialized databases and
comparative analysis tools
Direct comparison of material
characteristic data
Data from regulator / source
or fuel manufacturers
Analytical measurement
capability
Fuel cycle / isotope
production knowledge
Subject matter
expertise, difficulty
of gathering data,
sophistication of
comparative
analysis tools, and
overall level of
effort gradually
increase with each
group level
Summary
•
Each country’s situation is unique with regard to nuclear
activities and NNFL development
–
Necessary mandate, organization, and technical approach
–
The characteristics included in each country’s library may be
different for the same materials
–
The sophistication of databases and comparative analysis tools
increase with scale of nuclear activities
•
Groups of countries can be defined based on complexity
and variety of activities
–
Facilitates developing guidance for groups of countries with
similar NNFL needs
–
Important for establishing the level of effort required to develop a
NNFL early in the process

Nuclear forensics involves comparing data from unknown sources with known material characteristics to determine their origin. Establishing a national nuclear forensics library is crucial for identifying nuclear materials and promoting international cooperation in investigations. Key elements include information on material location and characteristics, expertise in material identification, and mechanisms for comparative assessments. Verification of material consistency is vital, and a library provides timely and confident responses to the question: "Is it ours?"
