Dear Sir or Madam:

Waterford 3 Core Operating Limits Report for Cycle 20 was revised to change the Azimuthal Power Tilt limit from less than or equal 0.03 to less than or equal to 0.05. Azimuthal Power Tilt values have been slightly higher than anticipated following restart from refueling outage

19. The increased limit allows for additional operating margin for the duration of Cycle 20 If you have any questions concerning this submittal, please contact John P. Jarrell, Regulatory Assurance Manager, at (504) 739-6685 There are no new commitments contained in this submittal.

Sincerey, JPJfjrm

WF3-NE-14-00002, Revision 1 Page 4 of 45 1.0 Scope and Objectives This report describes the development of the Waterford-3 Cycle 20 (W3C20) Rev. 1 Core Operating Limits Report (COLR). The report is developed by updating the Cycle 20 Rev. 0 COLR (Input Document (ID) 2.1) with information from ID 2.2.

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 20 Revision 0,"

April 29, 2014 2.2.

Letter, R. A. Loretz to C. Eastus, "Increase in Core Operating Limits Report (COLR)

Azimuthal Tilt Value for Waterford-3 Cycle 20," NF-WTFD-14-26, June 27, 2014.

3.0 Assumptions None 4.0 Detailed Discussion The information presented in ID 2.2 was used to update Section 3.2.3 in the COLR. The Azimuthal Power Tilt Limit has been changed from 0.03 to 0.05. The resulting W3C20 Rev. 1 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. The search revealed CR-WF3-2013-01755 which documented a typographical error in during the preparation of the Waterford 3 Cycle 19 COLR.

6.0 Summary of Results Using vendor provided justification; the W3C20 Rev. 0 COLR was updated to Revision 1.

7.0 Conclusions and Recommendations The W3C20 Revision 1 COLR has been developed and is acceptable to use.

8.0 References None 9.0 Attachments 9.1 W3C20 Revision 1 COLR (using formatting and numbering appropriate for the COLR).

WATERFORD 3 CORE OPERATING LIMITS REPORT CYCLE 20, REVISION 1 I. INTRODUCTION This CORE OPERATING LIMITS REPORT (COLR) has been prepared in accordance with the requirements of Waterford 3 Technical Specification 6.9.1.11 for Waterford 3 Cycle 20. The core operating limits have been developed using the NRC approved methodologies specified in Section II1. This is Revision 1 of the Cycle 20 COLR.

The major changes between the Cycle 20, Revision 1, COLR and the Cycle 20, Revision 0, COLR are listed below:

Section 3.2.3 was revised to change the Azimuthal Power Tilt limit from 0.03 to 0.05.

WATERFORD 3 COLR 3/4 2-4 CYCLE 20 REVISION 1

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.
