It's true that there are 4 pumps. but 1 one of them is on stand-by mode. so each of those 3 left pumps provide 33% of the flow need.
I am still searching for such a curve, it doesn't exist :)
678000 / 3 = 226,000 GPM per actual working pump. In order to calculate the pump head I need to have a performance curve that is in that range, but there is no source on the web. Do you know where I could find that?
Pumphouse is the place for monitoring the lake water (adding chlorine, blocking debris etc) and this water is pumped into condenser. I the water that goes from the lake to pumphouse and then to condeser is called a "raw service water" and is different than "service water".
Service water is used...
Q=mc\DeltaT
If the reactor is a typical 3000 MWthermal, and assuming 34% efficiency.
There is 2010 MW of energy that needed to be rejected. Considering 15 degree
temperature rise to the environment, the required mass flow is:
m= [ 2010x10^6 ] / [ 4.2x10^3 x 15 ]
m= 32000 kg/s
How do we...
I am referring to the pumps in the pumphouse that pum "Raw Service Water" which is taken from the lake into condenser. I think there are 4 of these pumps in the pumphouse which work at 33% and one of them is at stand-by mode.
