WATERFORD 3 CORE OPERATING LIMITS REPORT CYCLE 13, REVISION 0 I. INTRODUCTION This CORE OPERATING LIMITS REPORT (COLR) has been prepared in accordance with the requirements of Waterford 3 Technical Specification 6.9.1.11 for Waterford 3 Cycle 13. The core operating limits have been developed using the NRC approved methodologies specified in Section 1II. This is Revision 0 of the Cycle 13 COLR.

The major changes between the Cycle 13 and Cycle 12 COLR are listed below:

  • The Table of Contents List of Effective Pages was updated.
  • The List of Figures were revised to add COLR Figure 8A and to update the List of Effective Figure Pages
  • This Introduction section was revised to reflect the changes for Cycle 13.
  • The surveillance requirements for Section 3.1 :2.9 were changed based on results of a corrective action of Condition Report CR-WF3-2003-02844.
  • Clarifying notes were added below Sections 3.1.3.1.a and 3.1.3.1.b regarding the correspondence of these sections to Technical Specifications.
  • The title for Section 3.1.3.6 was revised to match references in Section III and the Table of Contents
  • Figures 6 & 7 were revised to provide vertical lines from the endpoints of the plotted line to the temperature axis. Also, the equation for the plotted line was added.
  • Section 3.2.4.b was revised to allow use of Figure 8A
  • Notes below the text of Section 3.2.4 for use with Figures 8, 8A & 9 were updated and.new notes were added.
  • Figure 8, was revised to incorporate cycle-specific limits for Cycle 13.
  • Figure 8A, was added to provide better resolution for the three power ranges in the lower portion of Figure 8.
  • Figure 9, was revised to incorporate cycle-specific limits for Cycle 13.
  • Section 111.7 was revised to add the document date.
  • Section 111.8 was added in accordance with License Amendment 191.

<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, using any operable CPC channel.

NOTES

1. The DNBR limit lines shown between the vertical ASI limit lines drawn at -0.17 and 0.22 on Figures 8, 8A, and 9 represent the minimum CPC-calculated DNBR required for operation in the power range displayed in the area above each line. Operation at lower power levels requires that a larger DNBR be maintained. For example, with ASI equal to

-0.17 and a core power of 85%, CPC calculated DNBR must be minimum of 2.55. At 79%

power and the same ASI value, the calculated DNBR must be at least 3.15. At 65% power and the same ASI value, DNBR must be a minimum of 4.21. At 90% power and an ASI value of +0.08, DNBR must be no less than 2.34.

2. The vertical ASI limit lines shown at -0.17 and 0.22 on Figures 8, 8A, and 9 may be considered as extending beyond the maximum DNBR value shown on 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 three power ranges in the lower portion of Figure 8.
4. Equations are provided on Figures 8, 8A, and 9 to assist in determining DNBR limits in the sloped portions of the plots.
