MCEI-0400-349 Page2 Revisi.on 1 McGuire 1 Cycle 26 Core Operating Limits Report Implementation Instructions For Revision 1 Revision Description and CR Tracking Revision O of the McGuire Unit 1 Cycle 26 .COLR contains limits specific to the reload core.
Revision 1 of the McGuire Unit 1 Cycle 26 COLR is issued to adjust the burnup dependent minimum required CLA boron concentration for bumups > 200 EFPD. The revised values reflect the actual Cycle N-1 shutdown conditions, as opposed to applying an assumed shutdown window.
Revision 1 is being issued in accordance with NCR 02190882.
The power distribution monitoring factors from Appendix A of Revision O remain valid and are not transmitted as part of Revision 1.
Implementation Schedule The McGuire Unit 1 Cycle 26 COLR requires the reload 50.59 (AR #02147708) be approved prior to implementation and fuel loading.
Revision 1 to the McGuire Unit 1 Cycle 26 COLR is effective upon receipt.
The McGuire Unit 1 Cycle 26 COLR will cease to be effective during No MODE between cycles 26 and 27.
Data Files to be Implemented No data files are transmitted as part of this document.

F ~TP *K(Z)IP forP > 0.5 p~TP *K(Z)/0.5 for P :S 0.5 where, P = (Thermal Power)/(Rated Power)
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 Sections 2.6.5 and 2.6.6.
2.6.2 p~TP = 2.70 x K(BU) 2.6.3 K(Z) is the normalized FQ(X,Y,Z) as a function of core height. The K(Z) function for Westinghouse RFA fuel is provided in Figure 4.
2.6.4 K(BU) is the normalized FQ(X,Y,Z) as a function of bumup. F ~TP with the K(BU) penalty for Westinghouse RFA fuel is analytically confirmed in cycle-specific reload calculations. K(BU) is set to 1.0 at all bumups.

- f1 (t.I) negative breakpoints and slopes for OT.t.T are less restrictive than the OP.t.T fi{Af) negative breakpoint and slope. Therefore, during a transient which challenges the negative imbalance limits, OPL'i.T f2 (Af) limits will result in a reactor trip before OT.t.T f1 (Af) limits are reached. This makes implementation of an OTL'i.T f1 (ti.I) negative breakpoint and slope unnecessary.
