This Radial Peaking Factor Limit Report is provided in accordance with paragraph ; 6.9.1.9 of the Braidwood Unit 1 Nuclear Plant Technical Specifications. The Fxy limit for RATED THERMAL POWER within specified core plans for Cycle SA shall be: ; a: For the lower core region from greater than or equal to 0% to less than or } equal to 50%:
- 1) For all core planes containing bank "D" control rods:
i FNPs2.700
- 2) For all unrodded core planes:
l FN"s1.755 { b: For the upper core region from greater than 50% to less than or equal to ; 100 %: ;
- 1) For all core planes containing bank "D" control rods:
- i i
FN"s2.052
- 2) For all unrodded core planes: i FN"s1.772 l t
These Fxy(z) limits were used to confirm that the heat flux hot channel factor FQ(z) will l be limited to the Technical Specification values of l i Fams ,2P} [xg>]for P>0.5 and i l Fams[5.00][xcz3]for Ps0.5 ; assuming the most limiting axial power distributions expected to result from the j 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 j
" Power Distribution Control and Load Following Procedures," WCAP-8403, September, ,
I 1974. Therefore, these Fxy limits provide assurance that the initial conditions assumed in the LOCA analysis and the ECCS acceptance criteria of 10 CFR 50.46 are met. .l 3 She attached figure for the plot of [F; *Pa.i] vs. Axial Core Height. Operating Limit Report 2
