l Wolf Creek Unit 1 Cycle 2 Radial Peaking Factor Limit Report This Radial Peaking Factor Limit Report is provided in accordance with Section 6.9.1.9 of the Wolf Creek Generating Station Technical Specifications.
The Fxy limits for Rated Thermal Power (3411 MWt) within specific core planes tor Cycle 2 shall be:
RTP 1.
F xy less than or equal to 1.86 for all planes containing bank "D" control rods, and 2.
F xy less than or equal to 1.64 for all unrodded core planes.
These Fxy(z) limits were used to confirm that the heat flux hot channel factor F (z) will be limited to the Technical Specification values of:
F (z) < [
[K(z)] for P > 0.5 and 9
F (z) < [4.64] [K(z)] for P < 0.5 q
assuming the most limiting axial power distributions expected to result from the insertion and removal of control banks B, C,
and D during operation, including the accompanying variations in the axial xenon and power distributions as described in -the " Power Distribution Control and Load Following Procedures", WCAP-8403, September,1974.
Therefore, these Fxy limits provide assurance that the initial conditions assumed in the LOCA analysis are met, along with the ECCS acceptance criteria of 10 CFR 50.46.
