Deliberate Unauthorized Act (DUA)

Any intentional action that has not been authorized and approved by proper authority.

(1) In the context of the nuclear explosive surety Standards, a DUA is one that is not sanctioned as part of an approved nuclear explosive operation or associated activity, but which could affect a NE or main charge high explosive part collocated with a pit.

(2) In the context of this Order, a DUA is of interest if it is performed with a malevolent intent to prevent authorized use (see DAU) of a nuclear weapon; create a nuclear detonation or other DUU; or to gain unauthorized control of a nuclear explosive.
