NUCLEAR REACTORS IN INDIA & FEATURES

India has 21 nuclear reactors in 7 nuclear plants in different states.

1. Tarapur Atomic Power Station (TAPS)
2. Rajasthan Atomic Power station (RAPS)
3. Madras Atomic Power Station (MAPS)
4. Kaiga Generating Station
5. Narora Atomic Power Station (NAPS)
6. Kakrapar Atomic Power Station (KAPS)
7. Kudankulam Nuclear Power Project (KKNPP)

Additional units are being constructed at Kudankulam, Rajasthan and kakrapar.

The types of Nuclear reactors and its features are as follows.

Reactor	PHWR  (Pressurized Heavy Water Reactor)	BWR (Boiling water Reactor)	FBR (Prototype Fast Breeder Reactor)	AHWR (Advanced Heavy Water Reactor)	WWER (Water water energetic reactor)
Remarks	Also called as CANDU – (Canada Deuterium Uranium Reactor)	Light water nuclear reactor	Fast neutron reactor. So FBR don’t have moderator	Next  generation PHWR	Similar to US’s PWR.
Fuel	Natural uranium	Enriched uranium	Mixed fuel –(Plutonium blended with natural uranium)	Thorium	Enriched uranium
Moderator	Deuterium  oxide (heavy water)	Demineralised water. (at 75 atm)	No moderator	Heavy water	Light water
Coolant	Heavy water (see "What is Heavy water?" post to know more)		Sodium	Heavy water	Light water
Power generation	Primary loop containing pressurized heavy water exchanges heat with the light water system(secondary loop) that drives the turbine.	Coolant system provides steam which drives the turbine.	Primary sodium loop + secondary light water loops	Like PHWR	Pressurized water  primary  loop transfers heat to light water system which drives the turbine.
in operation/ construction	Kaiga* Kakarapur Kalpakkam Narora Tarapur  Kota	Tarapur	Kalpakkam (Prototype FBR -To demonstrate the techno economic viability of fast breeder reactor. Additional one is being constructed.		Kudankulam
Planned	Gorakhpur * Chutka  Mahi banswara Kaiga	Kovvada – (ESBWR - Economically simplified boiling water reactor)		Site to be decided.	Kudankulam
