They are used in pressurized water reactors between the primary and secondary coolant loops.

The system pumped the water and glycol through coolant loops to reduce the temperature of the liquid.

It is a 1250 MWe gross reactor with two coolant loops.

Frequently, a chain of two coolant loops are used because the primary coolant loop takes on short-term radioactivity from the reactor.

Nevertheless, the presence of sodium-24 further necessitates the use of the intermediate coolant loop between the reactor and the turbines.

Three are in each main coolant loop.

The sodium coolant is already running through the coolant loop and has to be kept hot using electric heating elements so it does not solidify.

There are multiple coolant loops with 16 independent circuits, two circuits sharing a pump each.

The S5G was a pressurized water reactor plant with two coolant loops and two steam generators.

The reactor core was on the left of the screen, with the primary coolant loop to its immediate right.
