The "lD" bus feeder breaker from the start up auxiliary transformer was removed from the cabinet for preventative maintenance. The "lD" bus feeder breaker from the unit auxiliary trans-former tripped, causing a total loss of the ID bus. The bus loss caused a loss of several major components in the primary systems and the steam systems, causing a reactor scram due to low reactor vessel water levei The cause of the trip to the unit auxiliary transformer feeder breaker has not been determined.

- vibration. A control valve periodic -
test was in progress. The outage was extended approximately 16 hours due to " indicated" leakage inside the dry-well exceeding the amount of leakage allowed by Technical Specifications. The " indication" was determined to be a spurious - elec':rical signal
- instead of actual Icakage. The periodic test was revised to bypass a high vibration trip when the control valve periodic test is run. By re-placing a flow transmitter which had a faulty bellows assembly, the "indi-

SUMMARY
l Brunswick No. 1 l Brunswick Unit No.1 operated at a 38.5% capacity factor for the month of ! April. The following power changes and shutdowns occurred during the month: March 31: A trip of the unit auxiliary transformer feeder breaker caused a reactor scram. April 3: Power limited because of probicms with the HPCI automatic start test. April 5: High vibration during a control valve periodic test caused a turbine trip and a reactor scram. April 8: Problems with electrical grounds on #2 diesel generator caused a turbine trip and reactor scram. J I j April 15: A replica of the April 8th outage. Problems with the grounds on
#2 diesel generator.
April 22: Power reduced to perform condenser waterbox work. April 26: Excessive drywell leakage caused a unit separation to repack a valve. Total "down time" was 275.8 hours resulting in a 61.6% Availability Factor. For aore detailed information on individual outages, see the Unit Shutdowns and i Power Reductions Log (Appendix D) for this month. i l
