Aaron Dowdell Yes, I understand.  I thought they operated at a similarly high temp, but it appears they operate at ~150 degrees lower. "Most naval nuclear reactors are of the pressurized water type...A primary water circuit transfers heat generated from nuclear fission in the fuel to a steam generator; this water is kept under pressure so it does not boil. This circuit operates at a temperature of around 250 to 300 °C (482 to 572 °F). "
