IAEA
Safeguards Challenges• Comprehensive Design Information Examination and
Verification• High throughput requires additional measures to increase
the confidence about the absence of diversion and to confirm that the plant is operated as declared:• Near Real Time Accountancy (NRTA)• Measurement/Monitoring within the MBAs• Activities at Other Strategic Points to confirm the Operational Status
(random, short notice)
• Limited resources imply to rely on unattended measurement and monitoring systems as well as on automated evaluation software
• The approach needs to rely on independent DA samples and analytical analyses (On Site Laboratory)

IAEA
Main aspects of Safeguards Approach
• Design information examination / design information verification
• Verification of inventory changes (100% in/out)
• Verification of interim inventory for timeliness• Verification of physical inventory (annual)
including evaluation of MUF/SRD• Examination of operator records and reports

IAEA
Efficient Safeguards Approach
• Unattended measurement systems• Integrated data collection and evaluation
software• On-site laboratory• Well trained inspectors !!! ☺
