On'11/15/90 while warmire the' main. turbine prior to synchrontration, main tut?ine bearing e3 failed. A stator cooling coil leak on the generetor output bushing was subsequently identitled as needing repair also. The rain generotcr won synchrontred to the grid on 11/19/90.  !

'On 11/20/90 a main turbine-overspeed test was conducted at 10% power.

On 11/24/90 a turbine trip /recctor trip occurred while performing a plant shutdown due to high sulfatos in the reactor coolant system. '1he turbine trip was caused by a falso HSR high level trip logic
