NARRATIVE
SUMMARY
OF OPERATING EXPERIENCE Docket No.
50-301 Unit Name Point Beach Unit 2 Date July 7, 1986 Completed By C. W. Krause Telephone 414/277-2001 f
Unit 2 operated at approximately 485 MWe net throughout the period with one load reduction for load control and condenser tube checks which resulted in further power reduction due to secondary chemistry action levels.
On June 3, 1986, power was interrupted on the white instrument bus due to operator error i
while restoring the swing inverter to service after maintenance.
6 The power interruption on the bus caused a 6-8% turbine runback.
This event is detailed in LER 86-003 for Unit 2.
This event also caused a Unit 1 reactor trip which is reported in LER 86-003 for Unit 1.
l l
There was no significant safety-related maintenance performed j
during the period.
