In the context of nuclear weapons, what does "tamper" mean?

In the context of nuclear weapons, "tamper" refers to the act of performing an incorrect action involving a critical component that can potentially compromise the weapon's design or performance. This term is often associated with nuclear physics and weapon safety, where a tamper can inadvertently affect the behavior of the nuclear reaction or the integrity of the system.

A tamper may change how neutrons are reflected within the weapon, impacting criticality and energy release. If such actions are done improperly or without authorization, it can lead to adverse outcomes, including malfunctioning of safety systems or, in the worst case, an accidental detonation.

Understanding this role of tamper in nuclear weapon systems underscores the importance of rigorous safety protocols and training for personnel handling such sensitive materials, highlighting the severe consequences of mismanagement or improper handling in the context of weapon safety.
