Some reactors use gas (carbon dioxide) or liquid metal (sodium, potassium); some use organic fluids - mixtures of diphenyl and diphenyl oxide.
The US Navy experimented with a lead-bismuth liquid-metal coolant in the 60's but uses water (to my knowledge) today.
Most (all land-based reactors that I know of) use pressurized water. Plain water.
