SUMMARY

OF OPERATING EXPERIENCE FOR JULY 1998 The Plant began the month at full power. The reactor was manually scrammed from full power at 14:53 on July 21 due to a main feedwater pump trip. The reactor was brought critical at 06:59 on July 22, and the generator was brought on-line at 22:22 on July 22. The plant operated at a reduced power level during troubleshooting and maintenance of the main feedwater pump. The plant reached full power on July 27 and ended the month at full power.
