4 PEAKING FACTOR LIMIT REPORT FOR JOSEPH M. FARLEY UNIT 2 CYCLE 12 l

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

1 i

W(z) functions for Cycle 12 RAOC operation are shown in Figures 1 through 4. W(z) was calculated using the method described in Reference 1.

i l

This W(z) functio is used to confirm that the heat flux bot channel factor, Fo(z), will be limited to j

the Technical Specification values of:

VANTAGE 5 fuel:

5 Fo(z) 5 [2.45/P][K(z)] for P > 0.5, and, i.

Fo(z) s 4.90 [K(z)] for P s 0.5 low-Nysitic (LOPAR) fuel:

Fo(z) s [2.32/P][K(z)] for P > 0.5, and, Fo(z) s 4.64 [K(z)] for P s 0.5 C

The Fo (z) penalty factors are provided in Table 1.

This W(z) function, when applied to a power distribution measured under equilibrium conditions, 1

demanetrates that the initial conditions assumed in the LOCA are met along with the ECCS I

acceptance criteria of 10 CFR 50.46.

Fq (Z) PENALTY FACTOR Cycle Burnup (MWD /MTU) p,c(Z) Penalty Factor 531 1.0206 722-1.0226 913 1.0221 Nstes:

1.

The Penalty Factor, to be applied to Fo*(Z) in accordance with surveillance requirement 4.2.2.2.f, is the maxirr.um factor by which Fo*(Z) is expected to increase over a 39 EFPD interval (surveillance interval of j

31 EFPD p,lus the maximum allowable extension not to exceed 25 % of the surveillance interval per Technical Specification 4.0.2) starting from the burnup at which the Fo*(Z) was determined.

2.

Linear interpolation is adequate for intermediate cycle burnups.

3.

For all cycle burnups outside the range of the table, a penal y factor of 1.0200 shall be used.
