Which procedural safeguards govern operations with nuclear weapons or nuclear weapon systems?

The Nuclear Weapons Systems Safety Rules (WSSRs) are specifically designed to govern operations involving nuclear weapons or nuclear weapon systems. These rules provide comprehensive guidelines aimed at ensuring the safety and security of nuclear operations, detailing the necessary protocols to mitigate risks and prevent accidents.

WSSRs encompass a range of procedural safeguards, including operational limitations, safety measures, and compliance checks. This framework is crucial in a highly sensitive area like nuclear weapons handling, where the potential consequences of errors or failures could be catastrophic.

While other choices mention safety and regulatory concepts, they do not directly focus on governing nuclear weapons operations in the same structured manner that WSSRs do. For instance, Nuclear Safety Guidelines (NSGs) might offer broader principles for safety, and Defense Nuclear Safety Regulations (DNSRs) could be more related to the overarching regulations that support nuclear safety within the Department of Defense without being specific to weapon systems. Thus, WSSRs are the precise procedural safeguards tailored to the complex and sensitive nature of nuclear weapons operation regulations.
