INTRODUCTtON This report provides the cycle-specific limits for operation of CalvertCliffs Unit 1, Cycle 19. It contains the limits for: Shutdown Margin (SDM) Moderator Temperature Coefficient (MTC) Control Element Assembly (CEA) Alignment Regulating Control Element Assembly (CEA) Insertion Limits Linear Heat Rate (LHR) Total Planar Radial Peaking Factor (FxYT) Total Integrated Radial Peaking Factor (Fr,) Axial Shape Index (ASI) Reactor Protective System (RPS) Instrumentation - Operating Boron Concentration In addition, this report contains a number of figures which give limits on the parameters listed above. If any of the limits contained in this report are exceeded, corrective action will be taken as defined in the Technical Specifications. This report has been prepared in accordance with the requirements of Technical Specifications. The cycle specific limits have been developed using the NRC-approved methodologies given in the "List of Approved Methodologies" section of this report and in the Technical Specifications. COLR Revision 0 Initial release of the.Unit 1 Cycle 19 (U IC 19) COLR per Safety Evaluation SE00499 Revision 0. U 1C 19 is only allowed to operate in Modes 5, 6 or in a defueled condition. Although UICI9 is only authorized to enter Modes 5, 6, and defueled conditions, limits presented within this COLR relate to some parameters only applicable to operation in higher plant modes. Calvert Cliffs 1, Cycle 19 COLR Page 4 of 25 Rev.0
DEFINITIONS Axial Shape Index (ASI) ASI shall be the power generated in the lower half of the core less the power generated in the upper half of the core, divided by the sum of the power generated in the lower and upper halves of the core. ASI = lower - upper = YE lower + upper The Axial Shape Index (Yr) used for the trip and pretrip signals int the Reactor Protection System (RPS) is the above value (YE) modified by an appropriate multiplier (A) and a constant (B) to determine the true core axial power distribution for that-channel. Y, = AYE + B Total Integrated Radial Peaking Factor - FrT The Total Integrated Radial Peaking Factor is the ratio of the peak pin power to the average pin power in an unrodded core. Total Planar Radial Peaking Factor - F yT The Total Planar Radial Peaking Factor is the maximum ratio of the peak to average power density of the individual fuel rods in any of the unrodded horizontal planes. Calvert Cliffs 1, Cycle 19 COLR Page 5 of 25 Rev. 0
CYCLE SPECIFIC LIMITS FOR UNIT 1, CYCLE 19 3.1.1 Shutdown Margin (SDM) (SR 3.1.1.1) Tavg > 200 OF - Modes 3 and 4: The shutdown margin shall be equal to or greater than the limit line of COLR Figure 3.1. 1. Tavg S200 OF - Mode 5: The shutdown margin shall be > 3.0% Ap. 3.1.3 Moderator Temperature Coefficient (MTC) (SR 3.1.3.2) The Moderator Temperature Coefficient (MTC) shall be less negative than -3.0 x 10.' Ap/°F at rated thermal power. 3.1.4 Control Element Assembly (CEA) Alignment (Action 3.1.4.B.1) The allowable time to realign a CEA may be provided by the full core power distribution monitoring system (Better Axial Shape Selection System - BASSS) or COLR Figure 3.1.4, "Allowable Time to Realign CEA Versus Initial Total Inteirated Radial Peaking Factor (FrT).y, If COLR Figure 3.1.4 is used, the pre-misaligned F, value used to determine the allowable time to realign the CEA shall be the latest measurement taken within 5 days prior to the CEA misalignment. If no measurements have been taken within 5 days prior to the misalignment and the full core power distribution monitoring system is unavailable then the time to realign is zero (0) minutes. 3.1.6 Regulating Control Element Assembly (CEA) Insertion Limits (SR 3.1.6.1 and SR 3.1.6.2) The regulating CEA groups insertion limits are shown on COLR Figure 3.1.6. 3.2.1 Linear Heat Rate (LHR) (SR 3.2.1.2 and SR 3.2.1.4) The linear heat rate shall not exceed the limits shown on COLR Figure 3.2.1-1. The axial shape index power dependent control limits are given in COLR Figure 3.2.1-2. When using the excore detector monitoring system (SR 3.2.1.2): The alarm setpoints are equal to the ASI limits; therefore when the alarms are adjusted, they provide indication to the operator that ASI is not within the limits. The axial shape index alarm setpoints are shown as a function of fraction of thermal power on COLR Figure 3.2.1-2. A scaling factor (N-Factor) vs. FxyT is shown in COLR Figure 3.2.1-3. The fraction of thermal power shown in COLR Figure 3.2.1-2 must be scaled by the N-Factor to determine the axial shape index alarm setpoints as a function of fraction of rated thermal power.

DEFINITIONS Axial Shape Index (ASI) ASI shall be the power generated in the lower half of the core less the power generated in the upper half of the core, divided by the sum of the power generated in the lower and upper halves of the core. ASI = lower- upper . YE lower + upper The Axial Shape Index (Y1) used for the trip and pretrip signals in the Reactor Protection System (RPS) is the above value (YE) modified by an appropriate multiplier (A) and a constant (B) to determine the true core axial power distribution for that channel. Y, = AYE + B Total Integrated Radial Peaking Factor - FrT The Total Integrated Radial Peaking Factor is the ratio of the peak pin power to the average pin power in an unrodded core. Total Planar Radial Peaking Factor - FxyT The Total Planar Radial Peaking Factor is the maximum ratio of the peak to average power density of the individual fuel rods in any of the unrodded horizontal planes.

DEFINITIONS Axial Shape Index (ASI) ASI shall be the power generated in the lower half of the core less the power generated in the upper half of the core, divided by the sum of the power generated in the lower and upper halves of the core. ASI = lower - upper = YE lower + upper The Axial Shape Index (Y1 ) used for the trip and pretrip signals in the Reactor Protection System (RPS) is the above value (YE) modified by an appropriate multiplier (A) and a constant (B) to determine the true core axial power distribution for that channel. YI = AYE + B Total Integrated Radial Peaking Factor - FrT The Total Integrated Radial Peaking Factor is the ratio of the peak pin power to the average pin power in an unrodded core. Total Planar Radial Peaking Factor - FxyT The Total Planar Radial Peaking Factor is the maximum ratio of the peak to average power density of the individual fuel rods in any of the unrodded horizontal planes.

CYCLE SPECIFIC LIMITS FOR UNIT 1, CYCLE 19 3.1.1 Shutdown Margin (SDM) (SR 3.1.1.1) Tavg > 200'F - Modes 3 and 4: The shutdown margin shall be equal to or greater than the limit line of COLR Figure 3.1.1. Tavg *200 'F - Mode 5: The shutdown margin shall be > 3.0% Ap. 3.1.3 Moderator Temperature Coefficient (MTC) (SR 3.1.3.2) The Moderator Temperature Coefficient (MTC) shall be less negative than -3.0 x 10- 4 Ap/°F at rated thermal power. 3.1.4 Control Element Assembly (CEA) Alignment (Action 3.1.4.B.1) The allowable time to realign a CEA may be provided by the full core power distribution monitoring system (Better Axial Shape Selection System - BASSS) or COLR Figure 3.1.4, "Allowable Time to Realign CEA Versus Initial Total tnte rated Radial Peaking Factor (Fr).' If COLR Figure 3.1.4 is used, the pre-misaligned Fr value used to determine the allowable time to realign the CEA shall be the latest measurement taken within 5 days prior to the CEA misalignment. If no measurements have been taken within 5 days prior to the misalignment and the full core power distribution monitoring system is unavailable then the time to realign is zero (0) minutes. 3.1.6 Regulating Control Element Assembly (CEA) Insertion Limits (SR 3.1.6.1 and SR 3.1.6.2) The regulating CEA groups insertion limits are shown on COLR Figure 3.1.6. 3.2.1 Linear Heat Rate (LHR) (SR 3.2.1.2 and SR 3.2.1.4) The linear heat rate shall not exceed the limits shown on COLR Figure 3.2.1-1. The axial shape index power dependent control limits are given in COLR Figure 3.2.1-2. When using the excore detector monitoring system (SR 3.2.1.2): The alarm setpoints are equal to the ASI limits; therefore when the alarms are adjusted, they provide indication to the operator that ASI is not within the limits. The axial shape index alarm setpoints are shown as a function of fraction of thermal power on COLR Figure 3.2.1-2. A scaling factor (N-Factor) vs. FxyT is shown in COLR Figure 3.2.1-3. The fraction of thermal power shown in COLR Figure 3.2.1-2 must be scaled by the N-Factor to determine the axial shape index alarm setpoints as a function of fraction of rated thermal power.

DEFINITIONS Axial Shape Index (ASI) ASI shall be the power generated in the lower half of the core less the power generated in the upper half of the core, divided by the sum of the power generated in the lower and upper halves of the core. ASI = lower- upper . YE lower + upper The Axial Shape Index (Y1 ) used for the trip and pretrip signals in the Reactor Protection System (RPS) is the above value (YE) modified by an appropriate multiplier (A) and a constant (B) to determine the true core axial power distribution for that channel. Y, = AYE + B Total Integrated Radial Peaking Factor - FrT The Total Integrated Radial Peaking Factor is the ratio of the peak pin power to the average pin power in an unrodded core. Total Planar Radial Peaking Factor - FxyT The Total Planar Radial Peaking Factor is the maximum ratio of the peak to average power density of the individual fuel rods in any of the unrodded horizontal planes.

CYCLE SPECIFIC LIMITS FOR UNIT 1, CYCLE 19 3.1.1 Shutdown Margin (SDM) (SR 3.1.1.1) Tavg > 200 0F- Modes 3 and 4: The shutdown margin shall be equal to or greater than the limit line of COLR Figure 3.1.1. Tavg*52000 F - Mode 5. The shutdown margin shall be > 3.0% Ap. 3.1.3 Moderator Temperature Coefficient (MTC) (SR 3.1.3.2) The Moderator Temperature Coefficient (MTC) shall be less negative than -3.0 x 10-4 Ap/°F at rated thermal power. 3.1.4 Control Element Assembly (CEA) Alignment (Action 3.1.4.B.1) The allowable time to realign a CEA may be provided by the full core power distribution monitoring system (Better Axial Shape Selection System - BASSS) or COLR Figure 3.1.4, "Allowable Time to Realign CEA Versus Initial Total Integrated Radial Peaking Factor (VrT).y, If COLR Figure 3.1.4 is used, the pre-misaligned F, value used to determine the allowable time to realign the CEA shall be the latest measurement taken within 5 days prior to the CEA misalignment. If no measurements have been taken within 5 days prior to the misalignment and the full core power distribution monitoring system is unavailable then the time to realign is zero (0) minutes. 3.1.6 Regulating Control Element Assembly (CEA) Insertion Limits (SR 3.1.6.1 and SR 3.1.6.2) The regulating CEA groups insertion limits are shown on COLR Figure 3.1.6. 3.2.1 Linear Heat Rate (LHR) (SR 3.2.1.2 and SR 3.2.1.4) The linear heat rate shall not exceed the limits shown on COLR Figure 3.2.1-1. The axial shape index power dependent control limits are given in COLR Figure 3.2.1-2. When using the excore detector monitoring system (SR 3.2.1.2): The alarm setpoints are equal to the ASI limits; therefore when the alarms are adjusted, they provide indication to the operator that ASI is not within the limits. The axial shape index alarm setpoints are shown as a function of fraction of thermal power on COLR Figure 3.2.1-2. A scaling factor (N-Factor) vs. FxyT is shown in COLR Figure 3.2.1-3. The fraction of thermal power shown in CQLR Figure 3.2.1-2 must be scaled by the N-Factor to determine the axial shape index alarm setpoints as a function of fraction of rated thermal power. Calvert Cliffs 1, Cycle 19 COLR Page 6 of 25 Rev. 3 1
CYCLE SPECIFIC LIMITS FOR UNIT 1, CYCLE 19 When using the incore detector monitoring system (SR 3.2.1.4): The alarm setpoints are adjusted to protect the Linear Heat Rate limits shown on COLR Figure 3.2. l-1 and uncertainty factors are appropriately included in the setting of these alarms. The uncertainty factors for the incore detector monitoring system are:
- 1. A measurement-calculational uncertainty factor of 1.062,
- 2. An engineering uncertainty factor of 1.03,
- 3. A linear heat rate uncertainty factor of 1.002 due to axial fuel densification and thermal expansion, and 4.a For measured thermal power less than or equal to 50 percent but greater than 20 percent of rated full core power a thermal power measurement uncertainty factor of 1.035.
4.b For measured thermal power greater than 50 percent of rated full core power a thermal power measurement uncertainty factor of 1.020. 3.2.2 Total Planar Radial Peaking Factor (FxyT) (SR 3.2.1.1 and SR 3.2.2.1) The calculated value of FxyT shall be limited to < 1.70.
