ABSTRACT:
The thrust bearing for the shaft of a boiler feed pump in a nuclear reactor plant is cooled by a first stream of lubricant which is drawn from a sump by an impeller receiving motion from the shaft. The first stream constitutes one branch of a larger second stream which flows from the discharge end of the impeller. A third stream constituting another branch of the second stream is sprayed against and is cooled by the housing of the feed pump. The first and third streams are caused to reenter the sump by gravity flow. The exterior of the housing is provided with heat dissipating ribs.
