Turbine Generator tripped due to the per-formance of procedure 27.112.04 (Turbine Generator Valves ~ Low VAC on Load Test). The purpose of this procedure is to verify the opera-bility of the Turbine Generator Low Condenser Vacuum Trip Circuitry.

The procedure has been revised to prevent inadvertant turbine trips.

CODE CODE ACTION TO PREVENT (1) (HRS) (2) THE REACTOR (4) (5) RECURRENCE (3) 87-05 870218 F 5.3 A 9 N/A HA GENERAD Reactor was not shut down. Genera-tor was shut down again for addi-tional investigation of a possible ground fault. No evidence of a fault was found.

87-06 870223 F 22.2 A 9 N/A HA GENERAD Reactor was not shut down. Genera-tor automatically shut down. -The cause of the trip is att11 under investigation.

87-07 870226 F 58.4 A 3 87-002 HA .GENERAD Turbine trip and subsequent reac-tor was due to a generator negative ground fault. The most probable cause is that an aluminum strip in the. iso phase bus duct broke free and made contact with the bos which resulted in a ground. fault. During a future outage all other aluminum strips located in the iso phase cooling ducts.will be removed.
