Q1. In India, why are some nuclear reactors kept under "IAEA Safeguards" while others are not?
Explanation
IAEA safeguards apply to nuclear reactors using imported uranium as part of India’s international agreements. These safeguards ensure that the imported fuel is strictly used for civilian purposes and not diverted for military use. However, not all nuclear reactors in India are placed under IAEA safeguards. Reactors using domestic uranium are not subject to these safeguards allowing flexibility for strategic programs. By keeping reactors using domestic uranium outside IAEA safeguards, India maintains the flexibility to support its strategic programs without external oversight. As of recent data, out of India’s 22 operational reactors, 14 are under IAEA safeguards because they utilize imported fuel.
Additional insight:
Reactors Using Imported Uranium - Under IAEA Safeguards India imports uranium through civil nuclear cooperation agreements with countries like the U.S., Russia, and France. Reactors using imported uranium must be placed under IAEA safeguards to ensure peaceful usage. Example: Kudankulam Nuclear Power Plant (uses Russian-supplied fuel). Reactors Using Domestic Uranium - Not Under IAEA Safeguards India has natural uranium reserves, but they are insufficient to meet demand. Reactors using domestic uranium remain under sovereign control and are not necessarily under IAEA safeguards. Example: Tarapur (TAPS-1 & 2) and some PHWRs initially used domestic uranium and were not under safeguards.
