SUMMARY

- OCTOBER 1980 UNIT I The unit began the month at 100% power with normal operation.

On October 7 the unit tripped o's high RCS pressure following a main feed pump trip. The unit was returned to power later that day and power was held to about 45% for maintenance on main feed pump control problems.

The unit returned to 93% power on October 11.

On October 16 power was reduced to about 50% for more maintenance on "A" main feed pump. The unit was returned to 98% power on October 19 and continued operation there through the end of the month.

I ARKANSAS NUCLEAR ONE - UNIT 1 PERIODIC CORE P0k'ER DISTRIBUTION COMPARISON The radial power distribution comparison was performed at 259.9 EFPD.

The RMS (root :nean square) value of the difference between measured and predicted power at the 52 instrumented fuel assembly 1ccation was calculated. The RMS value was 0.026 at 259.9 EFPD. The value was within the acceptance criteria of 0.073.
