Study Notes

NUCE 304: Evaluative Methods for Nuclear Non-proliferation and Security

Course covers Nuclear Safeguards (Part 2)
Lecturer is Dr. Ahmed Alkaabi

Nuclear Material Accountancy (NMA)

NMA is the primary tool used by the IAEA to verify the accuracy of accounting information provided by facility operators and the State System of Accounting for and Control of nuclear materials
NMA is supported by containment and surveillance (C/S) measures
NMA responsibilities are at the facility, state, and IAEA levels

Elements of Nuclear Material Accounting

Establishing accounting areas
Record keeping
Measuring nuclear materials
Preparing and submitting accounting reports
Verifying the accuracy of nuclear material accounting information

Material Balance Areas (MBAs)

MBAs are areas within or outside a facility
The quantity of nuclear material in each transfer into or out of each MBA can be determined.
Physical nuclear material inventories in each MBA can be determined when necessary
IAEA design information is used in determining MBAs and selecting Key Measurement Points (KMPs)
KMPs are used to identify nuclear material flows and inventories

Criteria for Establishing MBAs

MBA size is related to the accuracy of material balance determination
Containment and surveillance are utilized where beneficial
Efforts to collect accurate flow measurements are concentrated on key measurement points
Multiple MBAs can be combined for facility accounting purposes
Special MBAs can be created around commercially sensitive processes, at the request of the state

Strategic Points in a Facility

Strategic points are selected locations during design review
Information necessary for safeguard implementation is gained and verified at these points
They can be locations where key material balance accounting measurements and containment/surveillance measures are conducted

Key Measurement Points (KMPs)

KMPs are locations where nuclear materials can be measured for material flow or inventory analysis.
Inputs, outputs (including discards), and storage locations within MBAs can be KMPs

Example: MBAs in a U Conversion and Fuel Fabrication Facility

Design Information Verification (DIV)

DIV's principal objective is to establish the basis for inspections at declared facilities while ensuring that the arrangements chosen remain appropriate.
This involves understanding all methods a facility could be used to further a state's nuclear weapons ambitions and approving facilities for dedicated peaceful uses, if applicable.
It also involves understanding the nuclear materials accountancy system and its interaction with national authorities.
The IAEA safeguards should be applied to verify the proper uses of nuclear materials, as defined by the findings of the State's system.

DIV Objectives

Develop a safeguard approach to detect diversions of nuclear materials
Detect facility misuse for weapons or unknown purposes
Detect facility modifications that could compromise safeguards
