SUMMARY
-0F OPERATING EXPERIENCE UNIT ONE SEPTEMBER, 1984 The status of Unit I remains shutdown with all fuel removed. The environ-ment and equipment continues to be maintained as needed. On August 31, 1984, an announcement was made by CECO. Corporate Offices that as of this date Unit I has been officially retired. Chemical cleaning activities are continuing. During the period September 13 through September 17, 1984, the "hundred hour" run of chemical cleaning solu-tion through the piping was accomplished. Since then, there has been three (3) . flush and drain operations to remove any residual chemicals and contamination. The solution injected has been very effective in drastically lowering dose rates.

SUMMARY
OF OPERATING EXPERIENCE UNIT THREE . SEPTEMBER, 1984 09-01 to 09-11 Unit 3 entered the month operating at a power level of 725 MWe and operated until September 11, 1984, when it was taken off-line to repair an EHC oil leak (the Rx remained critical). 09-11 to 09-30 The unit was brought on-line in the afternoon of September 11, 1984 and operated until September 25, 1984 when it was taken off-line.to repair a main condenser leak. After the Rx was subcritical, a scram occurred because of low condenser vacuum. Condenser inspection and repairs continued through the remainder of the month. Capacity factor for the month was 57.80% and availability was 78.81%.
