MILLSTONE POWER STATION UNIT 3 CORE OPERATING LIMITS REPORT, CYCLE 16 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, the Cycle 16 Core Operating Limits Report (COLR).

The MPS3 COLR has been revised to incorporate the following:

1 ) Editorial changes to increment the Cycle number from 15 to 16.

2) Editorial changes to cite the applicable Technical Specifications in the list of Analytical Methods (note: there were no additions, deletions or changes to the Analytical Methods).
3) Changes are made in the burnup range of applicability for W(Z) values in COLR Sections 2.11.3 and 2.11.4 to be consistent with the expected end of Cycle 16 burnup value of 21,600 MWD/MTU.
4) Cycle16-specific changes to the W(Z) values in Tables 1 through 3.

The COLR has been incorporated into the MPS3 Technical Requirements Manual.

If you have any questions or require additional information, please contact William D.

Bartron at (860) 444-4301.

The combination of the SMM Alarm Ratio setting and minimum count rate accounts for the time lag between the indicated and actual count rates, as well as other uncertainties.

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.3 1 Limit not applicable during either a THERMAL POWER ramp in excess of 5% of RATED THERMAL POWER per minute or a THERMAL POWER step in excess of 10% of RATED THERMAL POWER.

2 Section 2.14 was prepared by Dominion based on boron dilution analyses performed by Westinghouse.

3 This boron concentration bounds the condition of keff < 0.95 (all rods in less the most

)reactive two rods) and subcriticality (keff:<l1.0 with all rods out).
