An apparatus for supplying relatively cool feedwater to a heated pressure vessel, while moderating the thermal gradients within the apparatus and the pressure vessel. The feedwater apparatus is generally comprised of a feedwater inlet nozzle, thermal sleeve and sparger assembly which is structured to provide a thermal barrier and to lengthen the path of heat conduction through the feedwater inlet nozzle; to insure adequate support for the thermal sleeve and the sparger; to improve feedwater flow through the thermal sleeve and the sparger; and to facilitate the inspection and repair of the welds used to structure the feedwater apparatus.
