NRC MONTHLY OPERATING REPORT OPERATING SUP94ARY SEPTEMBER, 1983 UNIT 2 The Unit began the month offline in a continuation of last p:enth's outage.

The outage was performed to replace a reactor coolant pump seal and to conduct other maintenance.

On September 2, the Unit was returned to 100%

full power and operated there until September 26.

On this date, the. Unit was shutdown because of battery cells which failed to meet Technical Specification limits.

The Unit continued in Mode 5 for the remainder of the month.
