NRC MONTHLY OPERATING REPORT OPERATING

SUMMARY

- SEPTEMBER, 1979 The unit operated normally at 1007. reactor pcwer for the entire month.

1148 281

ARXANSAS NUCLEAR ONE - UNIT I Periodic Core Power Distribution Comparison A Radial Power Distribution ccrnparison was perfomed at 33.5 EFPD. The RMS (root mean square) of the differences between measured and predicted at the 52 instrumented fuel assembly locations was 0.0299 which is well within the acceptance criterion of 0.073.
