SUMMARY

The refueling outage preceding the Cycle 21 startup was approximately 30 days, starting on April 2,2011 and ending on May 03, 2011.The results of the Millstone 2, Cycle 21 low power physics testing and power ascension testing programs were in good agreement with the core design predictions. All measured parameters were within the review and acceptance criteria of the tests. All Technical Specification Limiting Conditions of Operation (LCOs) were met.Implementation of the Startup Test Activity Reduction (STAR) Program for Millstone 2 Cycle 21 has been accomplished in accordance with the steps outlined in WCAP- 16011 -A-P, Rev. 0 for (1) core design, (2) Control Element Assembly (CEA) lifetime, and (3) fuel fabrication. The STAR Applicability requirements for refueling have been accomplished for CEA coupling verification and startup testing. The application of the STAR Program allowed for the elimination of control rod worth measurements from the startup physics testing.May 2011 Serial No. 11-394/Enclosure/Page 3 2.

3. LOW POWER PHYSICS TESTING RESULTS Low Power Physics Testing was conducted at a power level of approximately 4 x 10-2 % power.May2011 Serial No. 11-3 94/Enclosure/Page 4 3.1 Unrodded Critical Boron Concentration The Critical Boron Concentration (CBC) measured with CEA Group 7 at 142 steps withdrawn and a reactor coolant system (RCS) temperature of 529.0°F was 1646 ppm.Adjusted to the prediction conditions of Group 7 at 180 steps withdrawn and an RCS temperature of'532°F yields an adjusted, measured CBC of 1661 ppm.Adjusted, measured unrodded CBC = 1661 ppm Predicted unrodded CBC = 1654 ppm Difference

-7 ppm (61 pcm)Review Criteria is +/- 50 ppm of the predicted CBC.Acceptance Criteria is +/- 1000 pcm of the predicted CBC.Review and Acceptance Criteria met? Yes.3.2 Moderator Temperature Coefficient The Isothermal Temperature Coefficient (ITC) measurements were performed at a boron concentration of 1646 ppm, an average RCS temperature of 530.5°F, and CEA Group 7 at 142 steps.The measured ITC at these conditions was +1.40 pcm/°F.Adjusted to the prediction conditions for an RCS boron concentration of 1654 ppm and an RCS temperature of532°F yields an adjusted, measured ITC of+1.42 pcm/°F.Adjusted, measured ITC +1.42 pcm/°F Predicted ITC +2.20 pcm/°F Difference = -0.78 pcm/°F Review Criteria is +/- 2 pcm/°F of the predicted ITC.Review Criteria met? Yes.May 2011 Serial No. 11-394/Enclosure/Page5 The Moderator Temperature Coefficient (MTC) was determined by-subtracting the predicted Doppler Temperature Coefficient at the test conditions from the adjusted, measured ITC. The MTC at these conditions was +0.286 x 104 Ap/0 F. The Millstone 2 Technical Specifications require the MTC be less positive than+0.7 x 10-4 Ap/°F for power levels less than 70% power.Technical Specification limit met? Yes.3.3 Control Element Assembly Rod Worth Parameters CEA Rod Worth Parameters were not measured as allowed by WCAP-16011-P-A,"Startup Test Activity Reduction Program." 3.4 Rodded Critical Boron Concentration The CBC measured with CEA Group A inserted was not performed during Cycle 21 startup testing due to application of the STAR Program.3.5 Control Rod Drop Time Measurements The Millstone 2 Technical Specifications require that all CEAs drop in less than or equal to 2.75 seconds to the 90% inserted position, with RCS conditions at greater than or equal to 5 15°F and full flow (all reactor coolant pumps operating). Control rod drop time testing was done at an RCS temperature of 530°F with all four reactor coolant pumps operating. The average control rod drop time was 2.20 seconds to 90% insertion, with the fastest and slowest drop times being 2.08 seconds and 2.27 seconds, respectively. Technical Specification limits met? Yes.4. POWER ASCENSION TESTING RESULTS 4.1 Power Peaking, Linear Heat Rate and Incore Tilt Measurements The following core power distribution parameters were measured during the power ascension to ensure compliance with the Technical Specifications: Total Unrodded Integrated Radial Peaking Factor (FrT) is the ratio of the peak fuel rod power to the average fuel rod power in an unrodded core. This value includes the effect of Azimuthal Power Tilt.May 2011 Serial No. 11-394/Enclosure/Page 6* Linear Heat Rate (L-I Rt) is the amount of p'ower being produced per linear length of-fuel rod.* Azimuthal Power Tilt is the maximum difference between the powerngenerated in any core quadrant (upper or lower) and the average power of all quadrants in that half (upper or lower) of the-core divided by the average power of all quadrants in that half (upper or lower) of the core.The measurements of these parameters were: Power Level FrT Peak Linear Heat Rate Incore Tilt 66% 1.593 9.10 KW/ft 0.0041 100% 1.550 12.77 KW/ft 0.0048 The corresponding technical specification limits for all power levels for these parameters are:* Fr'T < 1.69 (Note -larger values of FrT are permissible at less than 100% power)* Peak Linear Heat Rate _< 15.1 KW/ft* Azimuthal Power Tilt _< 0.02 Technical Specification limit for FrT met? Yes.Technical Specification limit for LHR met? Yes.Technical Specification limit for Tilt met? Yes.4.2 Critical Boron Concentration Measurements CBC measurement was performed at 100% power at equilibrium xenon conditions. The CBC measured at 100% power with CEA Group 7 at 180 steps withdrawn and an RCS cold leg temperature of 544.3'F was 1198 ppm. The cycle average exposure at the time of this measurement was 215 Megawatt Days per Metric Ton Uranium (MWD/MTU). Adjusted to the prediction conditions of 100% power at an All Rods Out (ARO)condition and an RCS cold leg temperature of 545 'F yields an adjusted, measured CBC of 1199 ppm.Adjusted, measured 100% power CBC = 1199 ppm Predicted 100% power CBC = 1198 ppm Difference 1 ppm (8 pcm)Review Criteria is +/- 50 ppm of the predicted CBC.May 2011 Serial No. 11-394/Enclosure/Page 7 Acceptance Criteiia is+/- 1000 pcm 6f the predicted CBC.Review and Acceptance Criteria met?Yes.4.3 Hot Zero Power (HZP) to Hot Full Power (HFP) Critical Boron Concentration Difference The difference in the adjusted measured CBC performed at HZP and HFP was determined and compared to the design prediction. Predicted change in CBC from HZP to HFP= 441 ppm Adjusted, measured change in CBC from HZP to HFP = 463 )Dm Difference = -22 ppm Review Criteria is +/-_50 ppm of the predicted CBC difference. Review Criteria met? Yes.4.4 Flux Symmetry Measurements The core neutron flux'symmetry was measured at approximately 30% power using the fixed incore detector monitoring system. The differences between measured and calculated signals in operable incore detector locations ranged from -0.029 to +0.047.Review Criteria is +/- 0.10.Review Criteria met? Yes.The maximum azimuthal asymmetry in the neutron flux from measurements of the variation in incore detector signals from symmetric incore detectors was 2.60%Review Criteria is +/- 10%.Review Criteria met? Yes.4.5 Moderator Temperature Coefficient The ITC measurements were performed at a power level of 98.95 %, an RCS boron concentration of 1198 ppm, and an average RCS temperature of 570.38°F, and CEA Group 7 at 180 steps.May2011 Serial No. 11-394/Enclosure/Page '8 The measured ITC at these conditions was -'5.452 pcmr/F.The predicted ITC was determined for a power level of 100%, an RCS boron concentration of 1,205 ppm, an average RCS temperature of570°F, and at an ARO condition. The predicted ITC at these conditions was -5.290 pcm!°F.The predicted ITC adjusted for 98.95% power, an actual RCS boron concentration of 1198 ppm and an RCS temperature of570.38 0 F yields an adjusted, predicted ITC of-5.402 pcm/°F.Adjusted, Predicted ITC = -5.402 pcm/IF Measured ITC = -5.452 pcm/°F Difference = 0.050 pcm/°F Review Criteria is +/- 2 pcm/0 F of the predicted ITC.Review Criteria met? Yes.The MTC was determined by subtracting the predicted Doppler Temperature Coefficient at the test conditions from the measured ITC. The MTC at these conditions was -0.422 x 10-4 Ap/°F. The Millstone 2 Technical Specifications require the MTC be less than or equal to +0.4 x 10-4 Ap/0 F for power levels greater than 70%power.Technical Specification limit met? Yes.4.6 Reactor Coolant System Flow The RCS flow rate was measured using the secondary calorimetric method, in which the RCS flow rate is inferred by performing a heat balance around the steam generators and RCS to determine reactor power, and measuring the differential temperature across the reactor core to determine the enthalpy rise.The measured RCS flow rate at 100% power was 385,974 gallon per minute (GPM).When 13,000 GPM is subtracted from the measured flow rate to account for measurement uncertainties, the Minimum Guaranteed Safety Analysis RCS Flow Rate is 372,974 GPM. This value is used to satisfy the technical specification surveillance requirement. May 2011 Serial No. 11-394/Enclosure/Page 9 The Millstone 2 Technical Specifications require the RCS flow rate to be greater than 360,000 GPM.Technical Specification limit met? Yes.4.7 Core Power Distributions The core power distribution measurements were inferred from the signals obtained by the fixed incore detector monitoring system. These measurements were performed at 66% power and 100% to determine if the measured and predicted core power distributions are consistent. The core power distribution map for 66% power, cycle average exposure of 10 MWD/MTU, non-equilibrium xenon conditions is shown in Figure 6.2. This map shows that there is good agreement between the measured and predicted values.The core power distribution map for 100%, cycle average exposure of 24 MWD/MTU, non-equilibrium xenon conditions is shown in Figure 6.3. This map also shows that*there is good agreement between the measured and predicted values.The review criteria for these measurements are: 1. The difference between the measured and predicted Relative Power Densities (RPDs) for core locations with an operable incore detector is less than 0.1.2. The Root Mean Square (RMS) deviation for radial and axial power distributions between the measured and predicted values is less than 0.05.Review Criteria met? Yes, for both 66% and 100% power.4.8 Reactor Coolant System Radiochemistry RCS radiochemistry analysis during the power ascension testing program and during subsequent power operation indicate activity levels with Iodine- 131 values of about 2.36 x 104 pCi/ml. These RCS activity levels show that all failed fuel assemblies have been discharged from the core.May 2011 Serial No. 11-394/Enclosure/Page 10 5.
