WATERFORD 3 CORE OPERATING LIMITS REPORT CYCLE 14, REVISION 0 I. INTRODUCTION This CORE OPERATING LIMITS REPORT (COLR) has been prepared in accordance with the requirements of Waterford 3 Technical Specification 6.9.1.1 1 for Waterford 3 Cycle 14. The core operating limits have been developed using the NRC approved methodologies specified in Section 1I1.This is Revision 0 of the Cycle 14 COLR.

The major changes between the Cycle 14 Revision 0 COLR and the Cycle 13 COLR are listed below:

  • The Table of Contents List of Effective Pages was updated.
  • The List of Figures was revised to add COLR Figure 9A and to update the List of Effective Figure Pages
  • This Introduction section was revised to reflect the changes for Cycle 14.
  • Figure 2 was changed to limit the most-negative hot full power MTC to less negative than -3.9 x 104 ApI -F.
  • Section 3.2.1 was revised to list the Linear Heat Rate with COLSS in service as 12.9 kw/ft and the Linear Heat Rate with COLSS out of service as 13.2 kw/ft.
  • Figure 6 represents the Linear Heat Rate for Cycle 14 of 12.9 kw/ft and constant with temperature with COLSS in Service
  • Figure 7 represents the Linear Heat Rate for Cycle 14 of 13.2 kwlft and constant with temperature with COLSS Out of Service
  • Section 3.2.4.c was revised to allow use of Figure 9A
  • Notes below the text of Section 3.2.4 for use with Figures 8, 8A, 9 & 9A were updated and new notes were added.
  • Figure 8, was revised to incorporate cycle-specific limits for Cycle 14.
  • Figure 8A, was revised to provide better resolution for the four power ranges in the lower portion of Figure 8.
  • Figure 9, was revised to incorporate cycle-specific limits for Cycle 14.
  • Figure 9A, was added to provide better resolution for the four power ranges in the lower portion of Figure 9.
  • Section 3.2.7 was revised to incorporate the new Axial Shape Index (ASI) limits required to support extended power uprate and the Cycle 14 COOS analysis.
  • Section 111.6 was revised to correct the document number.
  • Sections 111.9 and 111.10 were added in accordance with License Amendment 199, Extended Power Uprate.
  • Sections 111.1 1, 111.12 and 111.13 were added in accordance with License Amendment to modify TS 6.9.1.1 1.1, Core Operating Limits Report. These methodologies were added to support eventual adoption of Zirconium Diboride as an integral fuel burnable absorber and ZIRLOTM fuel rod cladding.

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 drawn 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.
