Subject: ELECTRICAL FAULT CAUSED LOSS OF START-UP POWER (EVENT 38186)
Reportable Event Number: 38186

Discussion:

On Saturday, August 4, 2001, the licensee experienced an electrical fault
that caused the loss of startup transformer power to both units while
both units were operating at 100 percent power (reference Event Number
38186).  The loss of startup power resulted in loss of electrical power
to outbuildings and a precautionary start signal to the emergency diesel
generators.  All six emergency diesel generators started as designed for
this condition; none of them tied on to the emergency electrical buses
since offsite power was maintained through the 500 kV supply lines. Both
units remained at full power. This morning report is an update to that
event report.

Power to the Unit 2 startup transformer was restored on Sunday,
August 5, 2001.  Using a crosstie from the Unit 2 startup transformer,
startup power to Unit 1 was restored by midday on Monday, August 6.
During its investigation, the licensee found that a 230 kV/12 kV fused
disconnect switch on the outside wall of the turbine building in Unit 1
was badly damaged. In addition, during the event, the licensee lost power
to several buildings such as the administration building and the
simulator. The licensee knew that electrical power would not be restored
to administrative buildings by Monday and instructed nonessential
personnel not to report to work. Power was restored to the administrative
buildings early on Tuesday, August 7.

The licensee is investigating the causes for the event and is repairing
damaged equipment.

Regional Action:

The senior resident inspector will continue to follow up on licensee
activities in accordance with the baseline inspection program.
