Which of the following is a Nuclear Surety report which is a mishap not included in the accident category?

• A. incident
• B. accident
• C. near-miss
• D. anomaly

Answer: (A)

In nuclear surety reporting, events are categorized by safety impact so we can track and address risks appropriately. A mishap that does not meet the criteria for an accident is labeled an incident. This covers events that involve a deviation or potential risk but do not result in actual damage, injury, or release. For example, a fault indication that is quickly resolved or a procedural deviation that is corrected before any harm occurs would be logged as an incident, not an accident. An actual accident would imply measurable damage or a release; a near-miss is a close call that could have caused a mishap but did not; an anomaly is a deviation from normal operation that may require investigation but isn’t itself a mishap. Therefore, the term that describes a mishap not in the accident category is incident.
