A water-cooled reactor is generally dwarfed by the cooling systems attached to it.

The reactor is normally cooled by water from the river.

Immediately following removal from the reactor core, the spent fuel must be cooled in a water pool at the plant.

The reactor is cooled by an inert, fireproof gas, so it cannot have a steam explosion as a light-water reactor can.

The reactor was graphite moderated and water cooled.
From the en.wikipedia.org
It is a tank-type 6 MW reactor that is moderated and cooled by light water and uses heavy water as a reflector.

Even if India is now going forward with a water cooled thorium reactor it is a long way from developing anything truly functional.

Initial designs by the Metallurgical Laboratory and DuPont used helium for cooling, before they determined that a water-cooled reactor would be simpler, cheaper and quicker to build.

A boiling water reactor is cooled and moderated by water like a PWR, but at a lower pressure, which allows the water to boil inside the pressure vessel producing the steam that runs the turbines.
