MILLSTONE POWER STATION UNIT 3 UPDATE TO THE CYCLE 18 CORE OPERATING LIMITS REPORT In accordance with the Millstone Power Station Unit 3 (MPS3) Technical Specifications (TSs ), Section 6.9.1.6.d, Dominion Nuclear Connecticut, Inc., hereby submits, as Enclosure 1, an update to the Cycle 18 Core Operating Limits Report (COLR).

The MPS3 Cycle 18 COLR was updated to be consistent with changes to the MPS3 TSs that were recently approved by the NRC under License Amendment 268 (ADAMS Accession No. ML16131A728). License Amendment 268 revised the MPS3 technical

specifications to:

(1) allow the use of Dominion nuclear safety and reload core design methods; (2) allow the use of applicable departure from nucleate boiling ratio design limits for VIPRE-D; (3) update the approved reference methodologies cited in TS 6.9.1.6.b; (4) remove the base load mode of operation which is not a feature of the Dominion Relaxed Power Distribution Control power distribution control methodology; and (5) address the issues identified in Westinghouse Nuclear Safety Advisory Letter (NSAL)-09-5, Rev. 1, Westinghouse Communication 06-IC-03, and NSAL-15-1 The MPS3 Cycle 18 COLR changes in support of License Amendment 268 include:

11 Formatting changes related to Item (3) were made to the COLR Analytical Methods section to maintain consistency with TS 6.9.1.6.b changes approved under License Amendment 268.

0 All references to base load operation were removed from the Cycle 18 COLR consistent with Item (4 ).

s The Cycle 18 COLR was updated to maintain consistency with the amended MPS3 TS Sections 3.2.1.1/4.2.1.1 (Axial Flux Difference) and 3.2.2.1/4.2.2.1 (Heat Flux Hot Channel Factor) related to Item (5). The associated Cycle 18 COLR limits were revised and new COLR items were added.

Serial No.16-399 Docket No. 50-423 Update to Cycle 18 Core Operating Limits Report Page 2 of 2 The approved methodologies from Items (1) and (3) are not included in the updated Cycle 18 COLR since they were not used to support the current M3C18 reload cycle design.

Item (2) does not require a COLR change.

The update to the Cycle 18 COLR has been incorporated into the MPS3 Technical Requirements Manual.

If you have any questions or require additional information, please contact Mr. Jeffry A.

The specified SMM Alarm Ratio setting ensures that the assumption that an alarm is generated at flux doubling in the Boron Dilution Event analysis remains valid. The count rate is displayed on the SMM.

2.15 Refueling Boron Concentration (Specification 3/4.9.1.1) 2.15.1 The boron concentration of all filled portions of the Reactor Coolant System and the refueling cavity shall be maintained at a boron concentration of greater than or equal to 2600 ppm. 4 3 Section 2.14 is based on cycle-specific boron dilution analyses performed by Dominion.

4 This boron concentration bounds the condition of keff ~ 0.95 (all rods in less the most reactive two rods) and subcriticality (keff ~ 1.0 with all rods out).
