Reference:
Cycle 4 Roload License Amendment, ULNRC-1850 dated October 25, 1988 In accordance with Callaway Technical Specification 6.9.1.9, Attachment 1 to this letter provides the required Cycle 4 Peaking Factor Limit Report. The report summarizes the W(z) functions that are to be used in Callaway Technical Specifications 4.2.2.2, 4.2.2.3, and 4.2.2.4 for F surveillance. g Because significant marain exists between the values and their analytically determined F (z)* P limit, Restricted Axial F9ux DifE8 bence (RAFDO) operation is not expected to be required for Cycle 4. For this no W(z)RAFDO values are supplied for Cycle 4.

These values were determined assuming CAOC operation with a +3,-12 percent AI band about the target flux difference. This information is sufficient to determine.the height dependent W(z)NO va es for Cycle 4 burmps 6 the range of 0 W.m i to 19140 MVD/MTU through the use of three point interpolation. Figure 4 includes a W(z)NO funct n that is bon &g for all Cych 4 burmps. l The bounding W(z)NO value s consenathe to use for any Cycle 4 burnup, however additional margin can be obtained by using the burnup dependent values. - For Cycle 4, margin exist between the maximum calculated F (z)*P rel values and the F (z)*P limit. Therefore the Restricted Axial Flux g Difference Operation (RAFDO) portion of the FQ surveillance Technical I Specification is not expected to be used for Cycle 4. As such, the i minimum allowable power level for Restricted AFD operation, APLND, for Callaway Cycle 4 is 100 percent of rated thermal power. No values of W(z)RAFD0 are pr vided for Cycle 4 The W(z) values were calculated using the method described in Part B l of Reference 1. The appropriate W(z) function is used to confirm that the heat flux i hot channel factor, F (z), will be limited to the Technical q Specification values of: l F (z) (<) 2.50*(K(z)) for P (>) 50 i 9 P I. ---2--_-__.__-__._.______--__-____.__-__u_..om-*____._.____m._-._._m__ .__-.m._-_m_
