What defines a Dual-Use nuclear material?

A Dual-Use nuclear material is characterized by its capability to serve both civilian and military purposes. This type of material possesses attributes that make it usable in peaceful applications, such as energy production, while simultaneously having the potential to be diverted for military applications, including the development of nuclear weapons.

The dual-use nature of these materials poses significant challenges for regulation and monitoring because while they can contribute to beneficial activities like electricity generation or medical applications, they also raise concerns about proliferation and security. This complexity is why understanding dual-use materials is critical in the context of nuclear surety and international non-proliferation efforts.

The other options do not encapsulate the essence of dual-use. First, materials that can only be used in civilian applications do not fit the definition, as they lack the potential for military use. Materials strictly regulated by international treaties could include a variety of items beyond just dual-use, and those restricted for domestic use only do not cover the broader implications of potentially being used for military ends.
