A bill to amend the Atomic Energy Act of 1954 to modify certain provisions relating to restricted data, and for other purposes.

Amends the Atomic Energy Act of 1954 to exclude from the definition of Restricted Data any data concerning the use of special nuclear material in the production of energy and information which is, or is derived from, information which has been published. Removes the sanctions against anyone who releases Restricted Data which that person has reason to believe will be used against the United States (if such person does so without intent to injure the United States or secure an advantage for any foreign nation).
