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...

What does DCD stand for?

Do you know the design of this type of pump, goes under which section of ASME?

If pump's motor load is around 33 ampere and 48 volts, how do you calculate the maximum flow and the head? Note the it is a vertical centrifugal pump

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.

Does anyone know what type of pump is used in nuclear plant's pump house?
