Gentlemen:
Enclosed is Licensee Event Report (LER) 95 004 00 for Comanche Peak Steam l
l Electric Station Unit 1. " Allowed Outage Time was Exceeded for the Turbine l
Driven Auxiliary Feedwater Pump which Tripped on Overspeed."
Via Reference 1 TU Electric has submitted its Licensee Event Report (LER)95-003 00 for Comanche Peak Steam Electric Station Unit 1. " Loss of Both Condensate and Both Feedwater Pumps Due To Failure of Non-safety Related f
Inverter Resulted in a Manual Reactor Trip." During this aforementioned l
event the Turbine Driven Auxiliary Feedwater Pump actuated due to lo lo l
Steam Generator alarms and subsequently tripped on overspeed. Reference 2 i
requested enforcement discretion to allow CPSES Unit 1 to remain in Mode 3.
I Hot Standby, while testing on the Unit 1 Turbine Driven Auxiliary Feedwater (TDAFW) pump was being performed. The enforcement discretion was granted via reference 3.
The subject Licensee Event Report is being submitted to satisfy the requirements of 10CFR50.73(a)(2)(1)(B), because the time requirements for the action statement were not met (see Reference 2).
Additionally, on June 21, 1995, a TDAFW pump overspeed trip was experienced on CPSES Unit 2 in an event unrelated to this LER.
TV Electric is in the process of evaluating the Unit 2 TDAFW trip, and will submit the evaluation in a supplement to the enclosed LER.
