Phase IFoundation

Background

Overview

India's unique position as a nuclear power outside the NPT, its commitment to non-proliferation, and the role of international bodies like IAEA are critical for understanding global security and India's foreign policy. Developments in verification technologies directly impact international nuclear governance.

Nuclear non-proliferation refers to the prevention of the spread of nuclear weapons and weapons technology. International safeguards, primarily implemented by the IAEA, are a system of technical measures applied to nuclear material and activities to verify that states are fulfilling their legal obligations not to divert nuclear material from peaceful uses to nuclear weapons or other nuclear explosive devices.
