The dividing line is the fuel: India's reactors that run on imported fuel are under IAEA safeguards, while those fuelled by India's own (indigenous) supplies are outside them. This follows the Separation Plan, notified under India's India-specific Safeguards Agreement with the IAEA, which covers only the civilian facilities India listed.
- ✓ (b) In a 2015 reply to the Lok Sabha, the Government said 13 reactors (Tarapur 1&2, Rajasthan 1 to 6, Kakrapar 1&2, Narora 1&2 and Kudankulam 1) are under IAEA Safeguards and use imported fuel, while the other eight, such as Kaiga 1 to 4, run on indigenous fuel.
- ✗ (c) Ownership or operator is not the divider: Tarapur Units 1&2 are safeguarded, but Tarapur Units 3&4 at the same station, fuelled by indigenous fuel, are not.
- ✗ (a) Official statements draw the line between imported and indigenous fuel, not between uranium and thorium.
Remember · Indian power reactors that use imported fuel (e.g. Tarapur 1&2, Kudankulam) are under IAEA safeguards; those on indigenous fuel (e.g. Kaiga, Madras, Tarapur 3&4) are not.
