What does the Department of Energy oversee in relation to nuclear material?

The Department of Energy primarily oversees the safeguarding and security of nuclear materials to ensure they are protected from theft, misuse, or accidents. This responsibility involves implementing strict security measures and protocols to monitor and control access to nuclear facilities and materials. The emphasis on safeguarding nuclear materials is a response to the potential risks associated with nuclear proliferation and terrorism.

In addition to security, the Department of Energy manages various aspects of nuclear energy and technology, but the top priority remains ensuring the safe handling and secure storage of nuclear materials, allowing for safe civilian nuclear energy use and other applications while preventing any dangerous scenarios. This aligns with the broader goals of national security and public safety in the context of the Cold War environment and beyond.
