V. C. Summer Cycle 25 JUNE 2019 1.0 Core Operating Limits Report This Core Operating Limits Report (COLR) for V. C. Summer Station Cycle 25 has been prepared in accordance with the requirements of Technical Specification 6.9.1.11.
The Technical Specifications affected by this report are listed below:
3.1.1.3 Moderator Temperature Coefficient 3.1.3.5 Shutdown Rod Insertion Limits 3.1.3.6 Control Rod Insertion Limits 3.2.1 Axial Flux Difference 3.2.2 Heat Flux Hot Channel Factor - Fq(z) 3.2.3 RCS Flow Rate and Nuclear Enthalpy Rise Hot Channel Factor 3.3.3.11 Power Distribution Monitoring System (PDMS) 1 Revision I
V. C. Summer Cycle 25 JUNE 2019 2.0 Operating Limits The cycle-specific parameter limits for the specifications listed in Section 1.0 are presented in the subsections which follow. These limits have been developed using the NRC-approved methodologies specified in Technical Specification 6.9.1.11.
2.1 Moderator Temperature Coefficient (Specification 3.1.1.3):
2.1.1 The Moderator Temperature Coefficient (MTC) limits are:
The BOL/ARO-MTC shall be less positive than the limits shown in Figure I.
The EOL/ARO/RTP-MTC shall be less negative than -4.8x10 4 !ik/k/°F (-48 pcm/°F).
where: BOL stands for Beginning of Cycle Life ARO stands for All Rods Out RTP stands for RA TED THERMAL POWER EOL stands for End of Cycle Life 2.1.2 The MTC Surveillance limit is:
The 300 ppm/ARO/RTP-MTC should be less negative than or equal to -4.lxl0 4 !ik/k/°F
(-41 pcm/°F).
2.1.3 The Revised Predicted near-EOL 300 ppm MTC shall be calculated using the following algorithm from Reference 2:
Revised Predicted MTC = Predicted MTC + AFD Correction*+ Predictive Correction**
- AFD Correction is 0.05 pcm/°F/%!iAFD.
- Predictive Correction is -3 pcm/°F.
If the Revised Predicted MTC is less negative than the SR 4.1. l.3b limit of
-4.lx10 4 !ik/k/°F, and all of the benchmark data contained in the surveillance procedure are met, then an MTC measurement in accordance with SR 4. l .1.3b is not required.
2.2 Shutdown Rod Insertion Limits (Specification 3.1.3.5):
The shutdown rods shall be withdrawn to at least 228 steps.
2 Revision 1
V. C. Summer Cycle 25 JUNE 2019 2.3 Control Rod Insertion Limits (Specification 3.1.3.6):
Control Bank A and B rods shall be withdrawn to at least 228 steps. Control Bank C and D Rod Insertion Limits are specified by Figure 2. Control rod overlap is 100 steps.
2.4 Axial Flux Difference (Specification 3.2.1):
2.4.1 The Axial Flux Difference (AFD) Limits for Relaxed Axial Offset Control (RAOC) operation for Cycle 25 are shown in Figure 3.
2.4.2 The Axial Flux Difference (AFD) target band during base load operations for Cycle 25 is:
BOL - EOL (0 - 23,000 MWD/MTU): +/-5% about a measured target value. The base load band will remain inside the RAOC band.
2.4.3 The Axial Flux Difference (AFD) Limits for Alternate Relaxed Axial Offset Control (RAOC) operation for Cycle 25 are shown in Figure 5.
2.4.4 The minimum allowable power level for base load operation, APL ND, is 75% of RATED THERMAL POWER.
2.5 Heat Flux Hot Channel Factor - FQ(z) (Specification 3.2.2):
fRTP FQ (Z) ::; _Q_ x K(Z) for P > 0.5 p
fRTP Thermal Power FQ (Z)::; _Q_ x K(Z) forP s; 0.5 where: P = - - - - - - - -
0.5 Rated Thermal Power 2.5.1 FiTP =2.45 2.5.2 K(z) is provided in Figure 4.
2.5.3 Elevation dependent W(z) values for RAOC operation at 150, 3000, 5000, 8000, 10000, 14000 and 20000 MWD/MTU are shown in Tables 1 through 2, respectively. This information is sufficient to determine W(z) versus core height in the range of 0 MWD/MTU to EOL bumup through the use of three point interpolation. Table 3 shows 3 Revision 1
V. C. Summer Cycle 25 JUNE 2019 FQ margin decreases for RAOC operation that are greater than 2% per 31 Effective Full Power Days (EFPD). These values shall be used to increase FoM(z) as per Surveillance Requirement 4.2.2.2.e. A 2% penalty factor shall be used at all bumups that are outside the range of Table 3.
2.5.4 Elevation dependent W(z) values for Alternate RAOC operation at 150, 3000, 5000, 8000, 10000, 14000 and 20000 MWD/MTU are shown in Tables 4 through 5, respectively. This information is sufficient to determine W(z) versus core height in the range of OMWD/MTU to EOL bumup through the use of three point interpolation. Table 6 shows FQ margin decreases for RAOC operation that are greater than 2% per 31 Effective Full Power Days (EFPD). These values shall be used to increase FoM(z) as per Surveillance Requirement 4.2.2.2.e. A 2% penalty factor shall be used at all bumups that are outside the range of Table 6.
2.5.5 Elevation dependent W(z)BL values for Baseload operation between 75 and 100% of rated thermal power with the Section 2.4.2 specified target band about a measured target value at 150, 3000, 5000, 8000, 10000, 14000 and 20000 MWD/MTU are shown in Tables 7 through 8, respectively. This information is sufficient to determine W(z)BL versus core height for bum ups in the range of O MWD/MTU to EOL bumup through the use of three point interpolation. Table 9 shows FQ margin decreases for base load operation that are greater than 2% per 31 Effective Full Power Days (EFPD). These values shall be used to increase FoM(z) as per Surveillance Requirement 4.2.2.4.e. A 2% penalty factor shall be used at all bumups that are outside the range of Table 9.
2.6 RCS Flow Rate and Nuclear Enthalpy Rise Hot Channel Factor - F,fk (Specification 3.2.3):
pN Thermal Power R = ~H where: P =- - - - - - - - -
FliJP x (1 + PF,fk x (1- P)) RatedThermalPower 2.6.1 F:t = 1.62 2.6.2 PF~= 0.3 2.6.3 The Acceptable Operation Region from the combination of Reactor Coolant System total flow and R is provided in Figure 6.
