Therefore, the sctpointsfor the various regions were selected based on a MCPR Limit of 1.30... " How does the NPPDjustiy using what appearsto be a slighttly less conservative value of APCR?
CNS Response Note: This question refers to question I of NLS2004006, "Response to Request for Additional Information Regarding Licensing Amendment Request to Revise Technical Specifications (TS)
Surveillance Requirements and TS Table for Mathematical Symbols and Use of Allowable Values in the Place of Analytical Limits" dated March 9, 2004.
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.
