FOURTH 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 AFW pump vents, drains, and turbine cooling water interconnecting piping have been designed and incorporated on the Design Criteria Drawing (DCD) (3BWO618-CA-01) and the physical drawings (3BWo418-CA series). Turbine bearing cooling water piping is undergoing rigorous analysis. TVA will supply additional input on this nonconformance upon completion of the rigorous analysis.
