WATERFORD 3 CORE OPERATING LIMITS REPORT CYCLE 9, REVISION 1 4

L INTRODUCTION i

This CORE OPERATING LIMITS REPORT (COLR) has been prepared in accordance with the requirements of Waterford 3 Technical Specification 6.9.5 for Waterford 3 Cycle 9. The core ;

operating limits have been developed using the NRC approved methodologies specified in Sectior.

III. This is Revision 1 of the Cycle 9 COLR.

NOTE: Due to extensive format changes, revision bars are only used here and to identify the technical information which has changed from Revision 0.

Format changes included in this revision are:

1) Reformatting of the entire COLR so that each page is now uniquely identified by page number. This will allow the individual COLR pages to be inserted behind the applicable Technical Specification pages.

2) Moving the COLR figures and tables behind the applicable pages for easier reference. As a result, former Figure 9 is now COLR Figure 2. The succeeding figures were renumbered as a result.

3) COLR Figure 4 was reworked to make it easier to read; however, no technical changes ,

were made to the information. '

4) The Index was reformatted to list the COLR Figures and COLR Tables by page number.

5) Added prepared by, reviewed by, and approved by signature blocks WATERFORD 3 Prege 5 CYCLE 9 REVISION 1

O CORE OPERATING LIMITS REPORT BORON DILUTION LIMITING CONDITION FOR OPERATION 3.1.2.9 With one or both start-up channel high neutron flux alarms inoperable, do not operate the plant in the configurations prohibited by COLR Tables 1 through 5 for the current Mode.

ACTION With one or both start-up channel high neutron flux alarms inoperable, the RCS boron concentration shall be determined at the applicable monitoring frequency specified in COLR Tables 1 through 5.

SURVEILLANCE REOUIREMENTS Each required boron dilution alarm shall be adjusted to less than or equal to twice (2x) the existing neutron flux (cps) at the following frequencies:

a. No sooner than one half hour after shutdown.

b. At least once per hour if the reactor has been shutdown < than 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months .

CORE OPERATING LIMITS REPORT DNBR MARGIN 3.2.4 The DNBR limit 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, 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.
