Anomalous Unit

A configuration in a nuclear explosive operation that has any of the following:

(1) Damage or other condition not identified as a credible deviation or otherwise explicitly addressed in an approved technical operating procedure.

(2) Damage or other condition that results in an unanalyzed configuration or a configuration not covered by a NES evaluation.

(3) Other damage or condition potentially adverse to nuclear explosive safety.

Minor damage or other non-conformances, such as units with scratches, bent connector pins, chipped insulators, stripped screws, etc., need not be considered as an anomalous unit unless the condition is potentially adverse to nuclear explosive safety.
