SUMMARY

- JANUARY, 1981 UNIT II i

Ii The Unit began this month's operation at a reduced power level while investigation associated with the condenser circulating water in.

leakage problem continued. Full power operation was reached on 1-13-81 af ter securing the condenser circulating water in-leakage.

The Unit tripped on 1-15-81 from 100% full power due to Control Element Assembly No. 02 falling into the core. Surveillance testing of the CEA's was being conducted at the time of the trip.

. Investigation revealed a dirty contact on one of the circuit boards associated with the CEA control logic caused the problem. A return to full power operation was accomplished on 1-16-81 and full power I

operation has continued thror.ghout the remainder of this reporting period.
