UNIT 2 On January 1, 1995, the unit's power level was at full power (3293 MWt and 1115 MWe). On February 9, 1995, at 0027 hours, the reactor scrammed due to a turbine trip. The turbine trip was caused by a ground to the main generator. The reactor was again critical on February 10 at 0135 hours and at 100% power on February 23 at 2300 hours. On March 30, 1995, at 1800 hours, the reactor scrammed due to low scram pilot
