2. Control rod drive flow to the Reactor vessel was reduced.

4. Reactor power was reduced and

- forward pump heat drain was routed to tlie condenser.

The apparent cause of the conductivity increase was the breakdown of an unidentified organic substance in the Reactor vessel.during power level increase. The substance came from the -

condensate storage tank which receives makeup from makeup water treatment and Radwaste. It is believed that the organic substance came from the Radwaste processes.

1. Additional maintenance was perfor-med on the Reactor Water Cleanup System. (Cont'd)

SUMMARY

BRUNSWICK No. 1 i

Brunswick Unit No. 1 synchroni:ed to the grid August 22, 1980 at 1400, completing a 2110.7 hour8.101852e-5 days 0.00194 hours 1.157407e-5 weeks 2.6635e-6 months refueling and maintenance outage. The outage was extended beyond its scheduled completion date because of unanticipated maintenance and regulatory problems. If further information on the refueling outage is needed, a detailed description is on file and may be obtained by contacting R. M. Coats at (919) 836-6031. The unit was forced "off-line" one other time the month of August resulting in a 9.4% capacity factor.

Unit availability factor was 22.4% for the month. A detailed description l of-the forced outage is provided in the unit shutdown and power reductions

, log (Appendix D) provided with this report. l There are 476 BWR and 154 PWR spent fuel bundles stored in the Brunswick Unit No. 1 fuel pool.
