During the time the "C" auxiliary feedwater pump was out of service, both electric-driven auxiliary feedvrater pumps were operable as required by Technical Specification 3.7.1.2. The "C" auxiliary feedwater pump was returned to'operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> as required by the Technical Specification.
This was the fifth reportable occurrence associated with the steam driven auxiliary feedwater pump. Two previous occurrences involved an open circuit in a solder joint (335-76-11) and a wiring diagram error ( 335-76-13) and are unrelated. The other three occurrences (335-76-22, 335-76-36 and 335-7>6-47) are related in that they involve control circuit corrosion. Action taken since the last reportable occurrence (335-76-47) has been the completion of jerouting of nearby steam drains away from the vicinity of the turbine. c )I Other means of long term corrective action are being studied. One possibility'~
under consideration to further correct the situation is to replace the+resent ~
junction boxes and relocate them to a position off the turbine, making:<hem less susceptible to the effects of heat and moisture buildup. This will require a cold shutdown of the plant of sufficient duration to permit accomplishment. (-335-77-10).
