V. C. Suinmer Cycle 12 July 1999 2.0 _ Operating Limits 1 I

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 Mmicrator Temperature CoefTicient (Specification 3.1.1.3):

2.1.1 The Moderator Temperature Coefficient (MTC) limits are:

The BOIJARO-MTC shall be less positive than the limits shown in Figure 1.

The EOl>ARO/RTP-MTC shall be less negative than -5x10 4 Ak/k/*F.

2.1.2 The MTC Surveillance limit is: .

i The 300 ppm /ARO/RTP-MTC should be less negative than or equal to -4.1 x10 4 Ak/k/*F I

where: BOL stands for Beginning of Cycle Life I ARO stands for All Rods Out l RTP stands for RATED TilERM AL POWER I EOL stands for End of Cycle Life 2.2 Shutdown Rod Insertion Limits (Specification 3.1.3.5):

The shutdown rods shall be withdrawn to at least 228 steps.

2.3 Control RmlInsertion Limits (Specification 3.1.3.6):

The Control Bank Insertion Limits are specified by Figure 2.

2.J Axial Flux Difference (Specification 3.2.1):

2.4.1 The Axial Flux Difference (AFD) Limits for RAOC operation for Cycle 12 are shown in Figure 3.

2.4.2 The Axial Flux Difference (AFD) target band during base load operations for Cyclel2 is:

BOL - EOL (0 - 23,320 MWD /MTU): iS% about a measured target value.

2.4.3 The minimum allowatle power level for base load operation. APL*, is 85% of RATED TilERM AL POWER.

2 Revision I

l V. C. Summer Cycle 12 July 1999 2.5 lleat Flux Ilot Channel Factor - F 9(z) (Specification 3.2.2):

RTP F

n F9(z)s p x K(z) for P > 0.5

.p RTP F0(z)s x K(z) for P s 0.5 Thennal Pown

0.5 where

P' = Rated Thermal Power 2.5.1 F

" = 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, 800,6,000,10,000, and 20,000 MWD /MTU are shown in Figures 5 through 9, respectively. This infcnnation is sufficient to detennine W(z) versus core height in the mnge of 0 MWD /MTU to EOL burnup through the use of three point interpolation.

2.5.4 Elevation dependent W(z)st, values for base load operation between 85 and 100% of rated thennal power with the item 2.4.2 specified target band about a measured target value at 150,3,400,6,000,10,000, and 20,000 MWD /MTU are shown in Figures 10 through 14, respectively. This infonnation is sufficient to determine W(z)nt; versus core height for bumups in the range of 0 MWD /MTU to EOL burnup through the use of three point interpolation.

2.6 RCS Flow Rate and Nuclear Enthalpy Rise Ilot Channel Factor - F N H (SPecification 3.2.3):

N F

g, all ""' I "*"

R N where: P = Rated Thermal Power F3 [x(I + PF3g x (1 - P)

RTP 2.6.1 F3g = 1.62 2.6.1 PF3 n = 0.3 2.6.3 The Acceptable Operation Region from the combination of Reactor Coolant System tc al flow and R is provided in Figure 15.

3 Revision I i

I V. C. Summer Cycle 12 July 1999 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, Up3n, to be applied to the Nuclear Enthalpy Rise flot Channel Factor FN shall be calculated by the following fonnula U All U

Fall = LO + 100.0 where: U ,9 3 = Uncertainty for enthalpy rise as defined in equation (5-19)in Reference 1.

If the Power Distribution Monitoring System is OPERABLE, as defined in Techincal Specification 3.3.3.11, the uncertainty, Upg. to be applied to the 11 eat Flux Ilot Channel Factor Fn(z) shall be calculated by the following formula U 4 n '

FQ = 1.0 + 100.0, e where: Un = Uncertainty for power peaking factor as defined in equation (5-19) in Reference 1.

U c = Engineering uncertainty factor.

= 1.03 If the Power Distribution Monitoring System is INOPERABLE, as defined in Technical Specification 3.3.3.11, the uncertainty, Up3;i, to be applied to the Nuclear Enthalpy Rise 110t Channel Factor FN 3 shall be calculated by the following fonnula Upgy; = UFAHm where: U FAHm = Base F3n measurement uncertainty.

= 1.04 If the Power Distribution Monitoring System is INOPERABLE, as defined in Technical Specification 3.3.3.11, the uncertainty, Upg, to be applied to the Heat Flux Hot Channel Factor F9(z) shall be calculated by the following formula Upq = U qu U e where: U, q

= Base Fq meawenent uncenainty.

= 1.05 U = Engineering uncertainty factor.
