Which document is a key regulatory guideline for nuclear surety in the U.S.?

The document that serves as a key regulatory guideline for nuclear surety in the U.S. is DOD 5210.41-M. This directive provides specific standards and guidelines to ensure the safety, security, and surety of nuclear weapons. It outlines the roles and responsibilities of personnel involved in nuclear operations, as well as the safety protocols that must be adhered to in order to prevent unauthorized access or mishandling of nuclear materials.

The directive established by the Department of Defense addresses critical areas including nuclear weapon safety, security measures, and the overall management of nuclear operations. By focusing on these key aspects, DOD 5210.41-M reinforces the framework necessary to maintain national security and ensure the safe handling of nuclear assets.

In contrast, the other documents mentioned may pertain to different aspects of nuclear policy or safety but do not have the same direct emphasis on nuclear surety as DOD 5210.41-M. This makes it the cornerstone document ensuring that all personnel and operations related to nuclear weapons meet stringent regulatory expectations.
