ENCLOSURE FARLEY UNIT 2 CYCLE 6 RADIAL PEAKING FACTOR LIMIT REPORT l

This Radial Peaking Factor Limit Report is provided in accordance with Paragraph 6.9.1.11 of the Joseph M. Farley Unit 2 Technical Specifications.

1 The F limits for RATED THERMAL POWER within specified core planes for Cycle k shall be:

x 1.

FpTP less than or equal to 1.77 for all core planes containing Bank "D

control rods, 2.

For all unrodded core planes:

P F[y less than or equal to 1.77 up to core elevations of 6.9 ft.

F!y less than or equal to 1.71 for core elevations above 6.9 ft.

TP These F v(z) limits are used to confirm that the heat flux hot x

channel Tactor F (z) will be limited to the Technical Specification q

values of:

F (z).< _2.31 [K(z)] for P > 0.5 and, q

7 F (z) $ 4,62 [M(z)] for P 1 0.5 q

assuming the most limiting axial power distributions expected to result from the insertion and removal of Control Banks 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-8385, September 1974.

Therefore, these F limits provide assurance that the initial xy conditions assumed in the LOCA analysis are met and the ECCS acceptance criterion limit of 2200 F for peak clad temperature is not exceeded.
