What are the two main categories of positions under the nuclear weapons PRP?

The two main categories of positions under the Nuclear Weapons Personnel Reliability Program (PRP) are classified as critical and controlled.

In this context, critical positions are those where individuals are directly involved in the handling and management of nuclear weapons and related systems, which require the highest standard of reliability and trustworthiness, as any lapses can have severe implications for national security. On the other hand, controlled positions do not have direct access to nuclear weapons but still play a significant role in the support and oversight of individuals in critical positions. These categories ensure that all personnel associated with nuclear weapons maintain an exceptional level of accountability and reliability.

This differentiation is essential for maintaining stringent security protocols and ensuring that all personnel are carefully vetted and monitored for any behaviors or conditions that could impair their ability to perform their duties satisfactorily, thereby safeguarding the integrity of nuclear operations.
