I.

SUMMARY

OF OPERAT11G EXPERIDCE On November 18, 1993, the unit was placed at 95% power in preparation for.a power rerate frun 3411 IW(t) to 3565 N(t). On Novanber 20, 1993, maximum rated thernal power was changed to 3565 m(t). The unit was placed at 97%

power after power rerate for the duration of the month, as a result of turbine nozzle inlet restrictions.

II.

MAJOR SAFFJIY RELATED PAINI'ENANCE ACI'IVITIES No major safety related maintenance activities were perforned during the nonth of November.
