Department of Energy information categorized as Restricted Data is classified under which policy?

The classification of Department of Energy (DOE) information as Restricted Data falls under the National Disclosure Policy-1 (NDP-1). This policy specifically governs the disclosure of classified nuclear weapon data and establishes the framework for protecting this sensitive information from unauthorized dissemination.

NDP-1 is critical for ensuring that data related to nuclear materials, designs, and technology remains secure, as it directly aligns with national security objectives. This policy serves to control the sharing and distribution of information that could compromise the safety and security of the nation, particularly regarding nuclear technologies and related activities.

In contrast, other policies mentioned do not specifically address the classification of Restricted Data within the DOE context. National Standards Policy and Federal Classification Policy are broader and do not focus solely on the nuances of nuclear-related information, while the Departmental Information Security Policy is more generic regarding information security without specifically addressing the concerned nuclear data classifications. Hence, NDP-1 is the most suitable answer as it directly relates to the governance of Restricted Data within the DOE framework.
