ARKANSAS NUCLEAR ONE - UNIT I Periodic Core Power Distribution Comparison A Rad'.al Power Distribution comparison was performed at 66.4 EFPD. The RMS (root mean square) of the differences between measured and predicted at the 52 instrumented fuel assembly locations was 0.029 which is well within the acceptance criterion of 0.073.
