500 degrees with preasures over 2000 pounds,something wrong here.600 pound steam is about 750 degrees.

You don't want steam in a reactor vessel, you need liquid coolant. I assume that you are checking saturation tables. Water at saturation temperature is borderline steam. You want a pressure that will prevent steam from occurring in the core and removing the cooling effect of the water. So 500 degrees and 2000 lbs is a perfectly acceptable combination.

OK,I think I understand,the water is pumped in at 2000psi but it only reaches 500 degrees,I can understand this now.I was thinking in the opposite direction when BFW is at 850 psi,to enter boiler generating 600psi steam generating 750 degrees.
