Reactor Coolant Pump Motor (RCPM) Lower Bearing Oil Coolers

Helical Fin Tubing Bearing Cooler
These pot* coolers cool the oil reservoir that cools the lower bearing. The heat exchangers themselves are circular in shape and use bare tubes or externally finned tubes for the required heat transfer surface needed to remove heat from the oil reservoir via the cooling water circulating through the tubes.

* Pot Coolers sit in a pot where oil circulates and the coil keeps it cool.
