SUMMARY

l'; On 7/10/97, at 1600, power was reduced to 94.5% due to an axial offset anomaly. On 8/19/97, at 0900, power was reduced over 2 days from 94.5% to 70.5% due to the axial offset anomaly. The plant operated at approximately 70% until 12/9/97, at 14:00 when power was increased to approximately 72%. On 12/22/97, at 13:00 power was increased to 74%. On 1/20/98, at 19:00 power was increased to 76.5%. On 1/30/98, at 14:00 power was increased to 80%. Power has been maintained at 80% since then to ensure adequate shutdown margin.
