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 manufacturers 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 cooling water interconnecting piping is currently under analysis (problems N4-1(2)CA-I,
-J, and -K) for seismic qualification. As a result of the preliminary analysis, physical drawings (3BWO418-CA) and design criteria diagrams (DCD) (3BWO618-CA) are being revised.
