TECHNICAL REQUIREMENTS MANUAL APPENDIX 8.1 CORE OPERATING LIMITS REPORT 2.13 Shutdown Margin Monitor Alarm Setpoint (Specification 3/4.3.5)*
2.13.1 The Shutdown Margin Monitor (SMM) minimum count rate and Alarmn Ratio Setting to meet LIMITING CONDITION FOR OPERATION (LCO) 3.3.5 shall be as shown below.
Tech. Spec. LCO SMM Alarm Ratio Setting Min. Count Rate (counts/sec) 3.3.5.a 1.50 1.0 1.25 0.6 3.3.5.b. 1 1.50 0.50 1.25 0.35 3.3.5.b.2 1.50 0.35 1.25 0.25 The combination of the SMM Alarrn 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.
2.14 Refueling Boron Concentration (Specification 3/4.9.1.1) 2.14.1 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.
Section 2.13 was prepared by Dominion based on boron dilution analyses performed by Westinghouse.
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) during the Cycle 10/11 refueling out- I age.
