First, this has nothing to do with Infinitis', but I really need to know the answer to this. Please don't delete this thread.

What type of fluid is currently used in US and Navy Nuclear reactors?

Thank you

NO, most of the engineers hang out here! That's why I put it here. I would have put it in the engineer section, but that place is dead

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.

I was looking on Google for information and found 2 different substances that are used:

Water pressurized to 2200+PSI

And

Lithium Hydride

*edit*

Does anyone know what the boiling temperature of water when pressurized to 2200+ PSI?
