An Anomaly is considered an unusual observable
condition which might result from diversion of nuclear material or
misuse of safeguarded items (see No. 2.4), or which frustrates or
restricts the ability of the IAEA to draw the conclusion that
diversion or misuse has not occurred (see No. 12.25). Examples of
possible anomalies would be:
- Denial or restriction of IAEA inspector access for
inspection
- Unreported safeguards significant changes to facility design or
operation
- A discrepancy involving 1 SQ or more of nuclear material
- A significant departure from the agreed recording and reporting
system
- Failure of the facility operator to comply with agreed
measurement standards or sampling methods
- A negative conclusion resulting from the evaluation of material
unaccounted for (MUF), shipper/receiver difference (SRD) or other
statistics
- IAEA seals on equipment detached by non-IAEA staff, lost or
showing signs of tampering
- Evidence of tampering with IAEA equipment
