Thank you again josepp. Pressure does supress boiling. In space you can boil water at 100 below zero.

Also a heat exchanger does seem to be an inefficient link in the chain don't you think? Do they use that for safety reasons or protect the pipes from extremely high pressures that steam produces?


The floor of this reactor does not seem to be as advanced as 3 Mile Island. So far it looks like it is just concrete with two big valves at the bottom.
