Which of the following is NOT one of the nuclear safety standards?

The selection of "Ensure adequate training for all personnel" as the option that is NOT one of the nuclear safety standards is accurate because while adequate training is critical for ensuring overall safety and operability within nuclear operations, it does not fall directly under the specific nuclear safety standards that govern the intrinsic safety and security of nuclear weapons.

Nuclear safety standards largely focus on the protocols and preventive measures designed to mitigate risk in the handling and operation of nuclear weapons. This encompasses preventing unintentional detonation, managing the consequences of accidents, and ensuring that weapons are not in a state that could lead to deliberate harm. Training, while vital for preparedness and operational efficacy, is generally considered a separate function that supports safety standards rather than being a standard itself.

The other options highlight specific safety directives aimed at avoiding dangerous situations during nuclear weapon storage and handling, which aligns directly with the core principles of nuclear safety. These include preventing deliberate prearming, ensuring that no accidental detonation occurs during an incident, and avoiding inadvertent actions, contributing to collective safety in the management of nuclear arms.
