The weaknesses with respect to the prioritization and evaluation of problems and corrective action effectiveness, as reflected in NRC findings identified over the past year, represent a substantive cross-cutting issue. Most notable was the failure to promptly address anomalous indications in the governor for the Unit 2 turbine-driven
auxiliary feedwater (
TDAFW) pump in August 2000. Further, after the failure of the
TDAFW pump, the evaluation of the problems with the governor was not thorough and did not address other contributors to the failure. Other examples included the failure to implement timely corrective actions to ensure correct voltage regulator settings for a Unit 2
emergency diesel generator, which resulted in a second identical occurrence one year later; and the failure to incorporate a corrective action to prevent recurrence of the inoperability of the Unit 2 C high pressure safety injection pump.
