Westinghouse Non-Proprietary Class 3 CORE OPERATING LIMITS REPORT FOR VOGTLE UNIT 3 CYCLE 1 2.6 Heat Flux Hot Channel Factor (FQ(Z)) (Constant Axial Offset Control (CAOC) W(Z)

Methodology)

(LCO 3.2.1)

The FQ(Z) limits in MODE 1 with THERMAL POWER 25% RTP and with the OPDMS not functional with respect to LCO 3.2.5 a, b, and c are:

CFQ 2.6.1 FC Q (Z) : S - for P > 0.5 P

CFQ FCQ (Z) :S - - for P :S 0.5 0.5 THERMAL POWER where: P =

RATED THERMAL POWER CFQ = 2.60 2.6.2 FC M Q (Z) = FQ (Z)

  • FMU Q (Z) where: FM Q (Z) represents the measured value of FQ(Z), and is obtained from power distribution measurement results.

FMU Q (Z) is a factor that accounts for fuel manufacturing tolerances (net effect being a factor of 1.03) and power distribution measurement uncertainty, the latter being dependent on the fraction of inoperable incore detectors and the detector measurement variability at the conditions of the power distribution measurement. Therefore, FMU Q (Z) is defined at the time of measurement per equations (4) and (5) of Reference 1.

CFQ 2.6.3 FW Q (Z) :S - - for P > 0.5 P

CFQ FWQ (Z) :S - for P :S 0.5

0.5 where

FW C Q (Z) = FQ (Z)

  • W(Z)

W(Z) is a cycle-dependent function that accounts for power distribution transients encountered during normal operation:

2.6.3.a The W(Z) function is dependent on core elevation and core burnup, as well as the assumed power level and M-Bank sequence, as specified in Table 2.6.3.a.

[

Ja,c 2.6.3.b A Penalty Factor shall be used to increase the FW Q (Z) in accordance with Surveillance Requirement 3.2.1.4 as specified in Table 2.6.3.b.
