India's journey as a nuclear power began with its first nuclear test in May 1974. This event marked its entry into the exclusive club of nuclear-armed states.
Despite its nuclear capabilities, India has consciously chosen to remain outside major international non-proliferation treaties. It is not a signatory to either the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) or the Comprehensive Nuclear Test Ban Treaty (CTBT).
Key Fact: India conducted its first nuclear test in May 1974, codenamed Smiling Buddha, asserting its technological prowess.
While not part of the NPT or CTBT, India maintains a strong commitment to nuclear safety and non-proliferation. It has a facility-specific safeguards agreement with the International Atomic Energy Agency (IAEA).
India actively seeks to participate in global civilian nuclear technology commerce. For this, it aims for an exemption from the Nuclear Suppliers Group (NSG), which would allow it to engage in nuclear trade despite its non-NPT status.
India's approach is characterized by a commitment to responsible nuclear stewardship while maintaining its strategic autonomy.
India has steadily gained entry into various multilateral export control regimes, signifying its growing integration into the global non-proliferation architecture. These memberships acknowledge India's robust export control systems.
Understanding India's position on NPT, CTBT, and its membership in regimes like MTCR, Wassenaar, and Australia Group is crucial for UPSC Mains GS-II and GS-III questions on International Relations and National Security.
India's nuclear program continues to advance, focusing on indigenous development and energy security. A significant recent development highlights its progress in advanced nuclear technology.
In 2023, India initiated the core loading of its Prototype Fast Breeder Reactor (PFBR) at Kalpakkam, Tamil Nadu. This marks a critical step towards achieving a closed nuclear fuel cycle and enhancing energy independence.
The PFBR at Kalpakkam is a key component of India's three-stage nuclear power program, designed to utilize thorium, of which India has vast reserves.
India maintains a clear and consistent nuclear doctrine. Its official commitment is to a policy of no-first-use of nuclear weapons.
This doctrine underscores India's defensive posture and its commitment to using nuclear weapons solely for deterrence and retaliation, not for initiating conflict.
