WF3-NE-14-00002, Revision 0 Page 4 of 46 1.0 Scope and Objectives This report describes the development of the Waterford-3 Cycle 20 (W3C20)Core Operating Limits Report (COLR).The report is developed by updating the previous cycle COLR (Input Document (ID)2.1)with information from the W3C20 Reload Analysis Report (ID 2.2)and the W3C20 Setpoints Document (ID 2.3).2.0 Input Documents The input documents used to develop the W3C20 COLR include the following:

2.1."Entergy Operations Waterford-3 Core Operating Limits Report for Cycle 19 Revision 2,"October 24, 2013.2.2.Letter, R.A.Loretz to C.Eastus,"Waterford Steam Electric Station Unit 3 Cycle 20 Final Reload Analysis Report,"NF-WTFD-14-5, February 17, 2014.See also Engineering Report WF3-NE-14-00001 2.3.Letter, R.A.Loretz to C.Eastus,"Startup Test and Setpoints Transmittal for Waterlord-3 Cycle 20,"NF-WTFD-14-12, April 11, 2014.3.0 Assumptions Historically, information for the COLR update is included in the cycle specific RAR and the cycle specific setpoints analysis.4.0 Detailed Discussion ID 2.2 contains the non-setpoints related information necessary to update the COLR.The document has sections specifically addressing the information necessary to update the COLR based upon the cycle specific analysis performed by the fuel vendor (Westinghouse).

Setpoints related changes are provided in ID 2.3.The received information was applied to 1D2.1.The resulting W3C20 COLR is found in Attachment 9.1.5.0 Operating Experience A PCRS search was performed looking for issues related to the development of a COLR as described here.None were found.6.0 Summary of Results Using vendor provided information; the W3C1 9 Rev.2 COLR was updated to reflect Cycle 20 information.

7.0 Conclusions and Recommendations The W3C20 Revision 0 COLR has been developed and is acceptable to use.8.0 References None WF3-NE-14-00002, Revision 0 Page 5 of 46 9.0 Attachments 9.1 W3C20 Revision 0 COLR (using formatting and numbering appropriate for the COLR).

For example, with ASI equal to-0.12 and a core power of 85%, CPC calculated DNBR must be a minimum of 2.62 with any CEAC Operable.At 79%power and the same ASI value with any CEAC Operable, the calculated DNBR must be at least 3.12.At 65%power and the same ASI value, DNBR must be a minimum of 4.28.At 90%power and an ASI value of+0.08, DNBR must be no less than 2.37.2.The vertical ASI limit lines shown at+/-0.12 and+/-0.22 on Figures 8, 8A, 9, and 9A may be considered as extending beyond the maximum DNBR value on the Y axis of the charts.Therefore, when monitoring DNBR with these figures, compliance is achieved at all power levels shown on a given figure when DNBR is greater than the largest DNBR value on the vertical scale.3.Figure 8A is provided to offer better resolution for the four power ranges in the lower portion of Figure 8.Figure 9A is provided to offer better resolution for the four power ranges in the lower portion of Figure 9.4.Equations are provided on Figures 8, 8A, 9, and 9A to assist in determining DNBR limits in the sloped portions of the plots.WATERFORD 3 COLR 3/4 2-6 CYCLE 20 REVISION 0 z E E C)0 C)Core Average ASI (COLR Figure 8)CYCLE 20 REVISION 0 Allowable DNBR with Any CEAC Operable (COLSS Out of Service)------Accptabie-Operation----
