Where is the Kudankulam Nuclear Power Plant located?

Concept: India's nuclear power plants are large, fixed infrastructure projects sited at specific coastal or riverside locations chosen for cooling-water availability and geological stability. Recalling which state hosts a given plant is a standard static-GK fact, not something derivable from the plant's name.

Application: The Kudankulam Nuclear Power Plant (KKNPP) stands at Kudankulam village in Tirunelveli district, on the southeastern coast of Tamil Nadu, beside the Gulf of Mannar. It is operated by the Nuclear Power Corporation of India Limited (NPCIL) in partnership with Russia's Rosatom, uses VVER-1000 pressurised-water reactors, and is currently India's largest nuclear power station by installed capacity.

• Kerala hosts no operating nuclear power plant, so it cannot be the site of Kudankulam.

• Karnataka's nuclear facility is the Kaiga Nuclear Power Plant in Uttara Kannada district — a separate plant from Kudankulam.

• Maharashtra's nuclear facility is the Tarapur Atomic Power Station — also a separate plant from Kudankulam.

Result: Tamil Nadu is therefore the state that hosts the Kudankulam Nuclear Power Plant.
