Title 42 › Chapter 23— DEVELOPMENT AND CONTROL OF ATOMIC ENERGY › Subchapter XI— CONTROL OF INFORMATION › § 2164
The President can allow U.S. agencies to share Restricted Data (classified nuclear information) with other countries in specific ways. The Atomic Energy Commission (with help from others) may share information about things like fuel processing, civilian reactor work, making special nuclear materials, health and safety, peaceful industrial uses, and related research. The Defense Department (with the Commission) may share design and other Restricted Data needed for defense planning, training against or with nuclear weapons, checking rival capabilities, and making delivery systems that work together. The President can also allow more sensitive exchanges: sharing weapon-related design data with a country that has already made big progress on weapons, and sharing military reactor research. The Energy and Defense Departments may share data needed for controlling and accounting for fissile material and weapons, treaty verification, and setting international classification rules — but only after the President finds the sharing will help common security and won’t create an unreasonable risk. All sharing must follow an official cooperation agreement, and any U.S. agency may share data if the agreement says it is allowed.
