Subject:

Core Operating Limits Report - Cycle 13 Revision 1, Change 1 Waterford Steam Electric Station, Unit 3 (Waterford 3)

Docket No. 50-382 License No. NPF-38

Dear Sir or Madam:

Waterford 3 Technical Specification 6.9.1.11.3 requires submittal of the Core Operating Limits Report (COLR) for each reload cycle. Revision 1 of the COLR for Waterford 3 Cycle 13 was submitted on November 17, 2003, by letter W3F1 -2003-0094.

The attached COLR Cycle 13 Revision 1, Change 1 revises Section 3.2.7, Axial Shape Index (ASI), to implement a 0.03 positive bias to the lower limit of the allowed ASI range (changed from -0.22 to -0.19) for 2 70% power. This change was necessary due to the upward shift of incore instrumentation due to a modification performed in Refueling Outage 12.

If you have any questions concerning this submittal please contact P.M. Melancon at (504) 739-6614.

There are no new commitments contained in this submittal.

Sincerely,

.~~~

WATERFORD 3 CORE OPERATING LIMITS REPORT CYCLE 13, REVISION 1, CHG. I 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 III. This is Revision 1 of the Cycle 13 COLR.

The major changes between the Cycle 13 Revision 0 COLR and the 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.

The changes between the Cycle 13 Revision 1 COLR and the Cycle 13 Revision 0 COLR are listed below.

• Figures 6 & 7 were revised to implement a 0.1 KWIFT reduction for the specified temperature range to account for greater than 500 but less than 600 plugged tubes in Steam Generator #1 (Ref. ER-WF3-2003-0117-000)

The change between the Cycle 13 Revision I COLR and the Cycle 13 Revision I Chg. I COLR is listed below:

• Section 3.2.7, Axial Shape Index, was revised to implement a 0.03 positive bias to the lower limit of the allowed ASI range (changed from -0.22 to -0.19) for g 70% power. This change was necessary due to the upward shift of incore instrumentation due to a modification performed in Refueling Outage 12 (Ref. Westinghouse Letter CWTR-03-190, dated 11/17/03).
