OF OPERATING EXPERIENCE MONTH: JULY 1996 For the month of July Unit i started out with the reactor being critical at low power and the generator was off-line due to transmission line dama9e causea by the storm of June 29th.

On July 2nd at 0339 the generator was placed on line. The Unit was limited in power output due to steam generator chemistry guidelines and the transmission distribution system (waiting on repairs).

On July 4th at 2229 the Unit was able to start the ramp up to full power operations because the transmission system was repaired. The Unit was at full power operation by 0014 of July 5th.
