BRAIDWOOD UNIT 2, CYCLE 5 RP_ERATING LIMIT REPQBT - Fxy PORTION This Radial Peaking Factor Limit Report is provided in accordance with paragraph 6.9.1.9 of the Braidwood Unit 2 Nuclear Plant Technical Specifications. The Fxy limit for RATED THERMAL POWER within specified core plans for Cycle 5 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:

RTP

                                                   $2.052
2) For all unrodded core planes:

Ff 51.735 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:

Ff $2.052

2) For all unrodded core planes:

Ff 51.817 These Fxy(Ij amits weio used to confirm that the heat flux hot channel factor FQ(z) will be limited to the Technical Specification values of Fa(z)s[5.00][K(2)]/orP50.5 and u m. u m-w

    ~

Fa(z)s[ 2.-50][K(z)]forP>0.5 P 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-8403, September 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.
