3 On 12/01/96 at 12:10: An aut a tic voltage control circuit in the exciter failed. which caused a protective relay to "open" and trip the turbine off-line; thus causing an automatic reactor scram on high power. After repairs were completed and attempting to return the unit to service; high turbine vibration was noticed. The turbine was placed on turning gear for investigation / repairs.

The unit will return to normal service when repairs are coupleted. (Total outage hours: 1331.8)
