The cause of the trip was a ground on an incorrectly abandoned cable on a transformer protective relay coil circuit. The cable was abandoned in 1999. The ground caused actuation of the relay and a turbine trip followed by the reactor trip. The abandoned cable was correctly terminated and the investigation identified additional abandoned cables that were not properly terminated. The configuration, of the additional abandoned cables, was corrected and the unit was returned to service.
