The Busitech Remotely Installed Nozzle Dam System is for use in Westinghouse Design Nuclear Steam Generators (S/G). These Nozzle Dams are used to isolate the primary channel head of the S/G from the primary coolant loop during the refueling process. This paper addresses the attributes of these Nozzle Dams utilized in the Westinghouse Steam Generator and does not address the Nozzle Dams utilized in the Combustion Engineering or Babcock and Wilcox Steam Generators. This Nozzle Dam System has a remote installation option which will allow installation of the Nozzle Dam with zero entry into the S/G primary channel head. The advantages of this total system is a significant reduction in radiation exposure, manpower and time of installation.
