THIRD INTERIM REPORT Description of Deficiency The auxiliary feedwater ( AFW) pumps were purchased without vent, drain, and turbine bearing cooling water interconnecting piping.
Connections to the pumps and turbines were supplied by the respective manufacturer with the understanding that TVA would provide the necessary piping design drawings and materials to meet TVA's and the pump specifications. The vents, drains, and turbine bearing cooling water interconnecting piping were not designed.
Interim Progress The auxiliary feedwater pump vents, drains, and turbine bearing cooling water interconnecting piping have been designed and incorporated on design criteria diagram (3BWO618-CA-01) and piping design drawing (3BWO418-CA-04, -08, and -12).
The turbine bearing cooling piping requires rigorous analysis, and therefore the design has been placed on hold until this analysis is issued.
