OF OPERATING EXPERIENCE MONTH: JUNE 1999 During the month of June, Unit 1 was base loaded. There were no shutdowns and only one power reduction for this month.

On Friday, June 25th, at 2012, Unit 1 generated l*/ 100 millionth megawatt-hour of electricity Unit 1 is the first reactor in the world rated at 560 megawatts gross capacity to achieve the 100 milliontil megawatt-hour milestone. It also is the first Westinghouse two-loop pressurized water reactor in the country to do so.

On the 17th, at '118, the Unit started to reduce power to allow work on 158 Feedwater Heater Controller (relay). The work was completed by 1419 and the l
