At'the beginning of the month, the plant was operating.at 100%. rated thermal power. On June 4th at 1358 while a calibration was being completed on Power Range Channel N42, a spike occured on Channel N43. ~With N42 still in test, the 2/4 RPS logic was made up to-cause a reactor' trip on Power Range Hi Setpoint Hi Trip.
