Dear Sir or Madam:
Waterford 3 Core Operating Limits Report for Cycle 19 was revised to correct a typographical error in Section 3.2.7, Axial Shape Index. Cycle 19 Axial Shape Index limit for COLSS Operable (when greater than 250 EFPD) required ASI to be "less than" +0.13 and greater than or equal to -0.16 when Thermal Power was greater than or equal to 50% of Rated Thermal Power; this was revised as follows: Cycle 19 Axial Shape Index limit for COLSS Operable (when greater than 250 EFPD) requires ASI to be "less than or equal to" +0.13 and greater than or equal to -0.16 when Thermal Power is greater than or equal to 50% of Rated Thermal Power. Please note that Waterford 3 has not reached 250 EFPD for Cycle
- 19. Attached is Revision 1 to Core Operating Limits Report for Cycle 19.
Please note that even though the attached Waterford 3 Cycle 19 Core Operating Limits Report Revision 1 is complete, there is a pagination error which has been captured in the Corrective Action Program.
There are no new commitments contained in this submittal. If you have any questions concerning this submittal, please contact Bryan Pellegrin at 504-739-6203.
Sincerely, BJfE

WF3-NE-12-00002, Revision 1 Page 4 of 46 1.0 Scope and Obiectives This report describes the development of the Waterford-3 Cycle 19 (W3C19) Rev.1 Core Operating Limits Report (COLR). The report is developed by updating the Cycle 19 Rev. 0 COLR (Input Document (ID) 2.1) with information from the W3C19 Setpoints Document (ID 2.2).
2.0 Input Documents The input documents used to develop the W3C19 Rev.1 COLR include the following:
2.1. "Entergy Operations Waterford-3 Core Operating Limits Report for Cycle 19 Revision 0,"
December 13, 2012.
2.2. Letter, R. A. Loretz to C. Eastus, "Startup Test and Setpoints Transmittal for Waterford-3 Cycle 19," NF-WTFD-12-32, November 30, 2012.
3.0 Assumptions None 4.0 Detailed Discussion The information presented in ID2.2 was used to update Section 3.2.7 in the COLR so that the entire section is consistent in its application of the limits. The resulting W3C19 Rev.1 COLR is found in Attachment 9.1.
5.0 Operatinq 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 W3C19 Rev.0 COLR was updated to Revision 1.
7.0 Conclusions and Recommendations The W3C19 Revision 1 COLR has been developed and is acceptable to use.
8.0 References None 9.0 Attachments 9.1 W3C19 Revision I COLR (using formatting and numbering appropriate for the COLR).

CORE OPERATING LIMITS REPORT DNBR MARGIN 3.2.4 The DNBR margin shall be maintained by one of the following methods:
a) When COLSS is in service and neither CEAC is operable: maintain COLSS calculated core power less than or equal to COLSS calculated core power operating limit based on DNBR decreased by 13% RATED THERMAL POWER.
b) When COLSS is out of service and at least one CEAC is operable:
operate within the region of acceptable operation shown on COLR Figure 8 (or 8A as appropriate), using any operable CPC channel.
c) When COLSS is out of service and neither CEAC is operable: operate within the region of acceptable operation shown on COLR Figure 9 (or 9A as appropriate), using any operable CPC channel.
NOTES
- 1. The various DNBR limit lines shown between the vertical ASI limit lines at +/-0.12 and +/-0.22 on Figures 8, 8A, 9, and 9A represent the minimum CPC-calculated DNBR value required for operation in the power range displayed in the area above each line. Operation at lower power levels requires that a larger DNBR value be maintained. 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.
