BEAVER VALLEY UNIT 2 CYCLE 2 RADIAL PEAKING FACTOR LIMIT REPORT This-Radial Peaking Factor Limit report is provided in accordance with paragraph 6.9.1.14 of the Beaver Valley Unit 2 Technical Specifications.
The F
limits-for RATED THERMAL POWER 'within specific core
. planes for Cycle 2 shall be:
x RTP 1.
F
$ 1.71 for all core planes containing D-BANK xy 2.
For unrodded core planes:
Fxy $ 1.69 from 1.8 ft. elevation to 2.5 ft. elevation Fxy 5 1.75 from 2.5 ft.. elevation to 10.2 ft. elevation Z
limits were. used to confirm that the heat flux hot These Fxy(ac) tor channel f
Fg(Z) will be limited to Lthe Technical Specification values of:
Pg(z) 5 [2.32] [K(z)] for P > 0.5 and, P
l l
l Fg(z) 5 [4.64] [K(z)] for P $ 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 accorapanying variations in the axial xenon and power distribution as described in the." Power Distribution Control and Load Following Procedures," WCAP-8403, September, 1974.
Therefore, these F limits provide assurance that the initial conditions assumed in Ehe'LOCA analyses are met, x
along with the ECCS acceptance criteria of 10-CFR 50.46.
