Extended Load Line Limit and ARTS Improvement Program Analyses for Cooper Nuclear Station Cycle 14, (NEDC-21892P, Rev 1, DRF B13-01512 Dated May 1991) Section 5.5 reads "Any set of RBM setpoints with a corresponding OLMCPR equal to or less than that of the limiting plant OLMCPR based on the other transient results can be utilized. The higher RBM setpoints (with a higher OLMCPR value) will afford more control rod movement flexibility without unnecessary alarms and rod blocks."

The Nuclear Regulatory Commission approved use of the Extended Load Line Limit and ARTS Improvement Program Analyses for Cooper Nuclear Station Cycle 14, NEDC-21892P, Rev I, May 1991 by Amendment 151 dated December 31, 1991.
