V. C. Summer Cycle 20                                                                        April 2011 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 1.
The EOL/ARO/RTP-MTC shall be less negative than -4.8x10 4 Ak/k/&deg;F (-48 pcn/&deg;F).
where:     BOL stands for Beginning of Cycle Life ARO stands for All Rods Out RTP stands for RATED 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. lxl04 Ak/k/OF
(-41 pcm/&deg;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/ 0 F/%AAFD.
                          **Predictive Correction is -3 pcm/&deg;F.
If the Revised Predicted MTC is less negative than the SR 4.1.1.3b limit of
                 -4.lx104 Ak/k/ 0 F, and all of the benchmark data contained in the surveillance procedure are met, then an MTC measurement in accordance with SR 4.1.1.3b is not required.
2.2      Shutdown Rod Insertion Limits (Specification 3.1.3.5):
The shutdown rods shall be withdrawn to at least 230 steps.

Control Bank A and B rods shall be withdrawn to at least 230 steps. Control Bank C and D Rod Insertion Limits are specified by Figure 2. Control rod overlap is 102 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 20 are shown in Figure 3.
2.4.2    The Axial Flux Difference (AFD) target band during base load operations for Cycle 20 is:
BOL - EOL (0 - 23,000 MWD/MTU): +/-5% about a measured target value.
2.4.3    The minimum allowable power level for base load operation, APLN, is 75% of RATED THERMAL POWER.
2.5    Heat Flux Hot Channel Factor - FQ(z) (Specification 3.2.2):
FR7 FQ (Z) *Q
               <        x K(Z)           for P > 0.5 P
FQ (Z):5 Q x K(Z)                for P _0.5     where: P         Thermal Power 0.5                                                Rated Thermal Power 2.5.1    FQlTP =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 7, respectively. This information is sufficient to determine W(z) versus core height in the range of 0 MWD/MTU to EOL burnup through the use of three point interpolation. A 2% penalty factor shall be used for RAOC operation to increase FQM(z) as per Surveillance Requirement 4.2.2.2e. A 2% penalty factor shall be used at all bumups.
2.5.4    Elevation dependent W(Z)BL values for Baseload operation between 75 and 100% of rated thermal power with the item 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 8 3                                   Revision 0

V. C. Summer Cycle 20                                                                       April 2011 through 14, respectively. This information is sufficient to determine W(Z)BL versus core height for burnups in the range of 0 MWD/MTU to EOL burnup through the use of three point interpolation. Table 15 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 FQM(Z) as per Surveillance.
2.5.5   The W(z) values are generated assuming that they will be used for a full power surveillance. When a part power surveillance is performed, using a flux map instead of the Power Distribution Monitoring System the W(z) values must be multiplied by the factor lI/P, when P is > 0.5. When P is < 0.5, the W(z) values must be multiplied by the factor 11(0.5). This is consistent with the adjustment in the FQ(z) limit at part power conditions.
2.6    RCS Flow Rate and Nuclear Enthalpy Rise Hot Channel Factor - F. (Specification 3.2.3):
FH              where: P =       Thermal Power R =
FR"  x (1 + PFN x(l-P))                  Rated Thermal Power 2.6.1    FLRJT =1.62 2.6.2   PFAH =0.3 2.6.3   The Acceptable Operation Region from the combination of Reactor Coolant System total flow and R is provided in Figure 5.
2.7    Power Distribution Measurement Uncertainty (Specifications 3.2.2 and 3.2.3):
If the Power Distribution Monitoring System is OPERABLE, as defined in Technical Specification 3.3.3.11, the uncertainty,  UFAH,  to be applied to the Nuclear Enthalpy Rise Hot Channel Factor FN A shall be calculated by the following formula:
U*
U FAH = 1.0 +
100.0 where: UAH     = Uncertainty for enthalpy rise as defined in equation (5-19) in Reference 1 or 4.0, whichever is larger.

UFQ      (1.0+1UQ        .Ue where: UQ      = Uncertainty for FQ(z) = 5.0 when confirming FQ(z) for RAOC or Base Load operation, or as defined in equation (5-19) in Reference 1 for all other purposes.
Ue     = Engineering uncertainty factor.
                      = 1.03 If the Power Distribution Monitoring System is INOPERABLE, as defined in Technical Specification 3.3.3.11, the uncertainty,   UFAH,  to be applied to the Nuclear Enthalpy Rise Hot Channel Factor FN     shall be calculated by the following formula:
UFAH =    UFAHm where: U FAHm = Base FH measurement uncertainty.
                        = 1.04 If the Power Distribution Monitoring System is INOPERABLE, as defined in Technical Specification 3.3.3.11, the uncertainty, UFQ, to be applied to the Heat Flux Hot Channel Factor FQ(z) shall be calculated by the following formula:
UFQ =Uqu' U where: Uqu     = Base FQ measurement uncertainty.
                      = 1.05 Ue    = Engineering uncertainty factor.
