Note: The measured FQ(X,Y,Z) shall be increased by 3% to account for manufacturing tolerances and 5% to account for measurement uncertainty when comparing against the LCO limits. The manufacturing tolerance and measurement uncertainty are implicitly included in the FQ surveillance limits as defined in COLR Sections 2.7.5 and 2.7.6.

2.7.2 F" =2.60 x K(BU) 2.7.3 K(Z) is the normalized FQ(X,YZ) as a function of core height. The K(Z) function for Westinghouse RFA fuel is provided in Figure 4.

2.7.4 K(BU) is the normalized FQ(X,YZ) as a function of burnup. K(BU) for Westinghouse RFA fuel is 1.0 for all burnups.

The fl(Al) "negative" breakpoints and the fl(AI) "negative" slope are less restrictive than the OPAT f2 (AI) negative breakpoint and slope. Therefore, during a transient which challenges the negative imbalance limits, the OPAT f2(AI) limits will result in a reactor trip before the OTAT fl(A1) limits are reached. This makes implementation of the OTAT fl(Al) negative breakpoint and slope unnecessary.
