TABLE 1 RADIAL PEAKING FACTOR LIMIT REPORT
~
This Radial Peaking Factor Limit Report is provided in accordance with Paragraph 6.9.1.11 of the Joseph M. Farley Unit i Te:hnical Specifications.
The Fxy limits for RATED THERMAL POWER within specified core planes for Cycle 14 shall be:
For VANTAGE 5 fuel:
RTP 1.
F,y less than or equal to 2.46 for all core planes containing Bank "D" control rods.
2.
For all unrodded core planes:
RTP F,y less than or equal to 1.90.
These Fxy(z) limits are used to confirm that the heat flux hot channel factor Fq(z) will be limited to the Technical Specification values of:
VANTAGE 5 fuel:
Fq(z) _A
[2Mi ][K(z)] for P > 0.5 and, P
Fq(z) 1 4.90 (K(z)] for P A 0.5 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 Fxy limits provide assurance that the initial conditions assumed in the LOCA analysis are met and the ECCS acceptance criterion limit of 2200'F for peak clad temperature is not exceeded.
