UNIT 'INO l
i September,1982 i
i f
i 9-1 to 9-2 Unit 'Iko entered the month operating at a power level l
of 692 We. However, shortly thereafter the unit j-scramed due to low water level caused by 2A RFP tripping l
on low oil pressure. A shaft seal failure was to blame.
I Imediate repairs were made and the unit returned to power.
f 9-2 to 9-24 The unit operated normally with no major problems attaining l
a power level of 692 me during this period.
i 9-24 to 9-30 A minor water leak in the hydrogen cooling system caused the unit to be shutdown the remainder of the period. The j
I leaking water soaked sane of the current transformers on 1
I the main generator output leads. They shorted to ground causing the generator output breakers to trip open. The f
