The plant stayed at 70.5% past the end of the month. Excess shutdown margin had been decreasing during the cycle due to the axial offset anomaly.

The load reduction to approximately 70% occurred when shutdown margin reached the plant administrative limit of 1350 pcm (the Technical Specification limit is 1300 pcm).
