Nuclear Non-Proliferation Act (US, 1978)

The Nuclear Non-Proliferation Act of 1978 (NNPA) strengthened United States controls on peaceful nuclear cooperation and exports after India's 1974 nuclear test exposed the proliferation risks of civil supply. It amended the Atomic Energy Act and directed United States policy towards stronger international safeguards, tighter export criteria and greater control over sensitive fuel-cycle activities.

The Act made full-scope International Atomic Energy Agency safeguards an export criterion for non-nuclear-weapon states after a transition period, subject to the statutory waiver and review process. It also reinforced conditions governing enrichment, reprocessing, retransfer and other uses of United States-obligated material or equipment. Nuclear Regulatory Commission licensing, executive-branch agreements for cooperation and congressional review perform different legal functions and should not be collapsed into a single approval.

The NNPA combines denial with inducement. It restricts supply when safeguards or cooperation conditions are not met, while promoting fuel assurances and international arrangements intended to make compliance viable. This architecture helped embed non-proliferation conditions in supplier practice, including through the Nuclear Suppliers Group. It did not create an automatic economy-wide sanction for every proliferation concern.

Implementation produced disputes with partners that held earlier supply agreements or rejected full-scope safeguards. The United States conflict with India over fuel for the Tarapur reactors demonstrated both leverage and substitution risk: denial could impose cost and signal a norm, but alternative suppliers could reduce its material effect. The statute remains part of the amended United States nuclear-export framework. Any current transaction requires review of the Atomic Energy Act, the applicable agreement for cooperation, regulations and subsequent law.
