t-This Peaking Factor Limit Report is provided in accordance with Paragraph 6.9.1.14 of the Sequoyah Unit 1 Technical Specifications.
The Cycle 3 W(z) functions for RAOC operation in the cycle bur,nup ranges of 0 to 2000 MWD /MTU, 2000 to 5000 MWD /MTU, 5000 to 11000 MWD /MTU, 11000 to 14000 MWD /MTU, 14000 MWD /MTU to EOL are shown in Figures 1 through 5 respectively. W(z) was calculated using the method described in Reference 1.
The appropriate W(z) function is used to confirm that the heat flux hot channel factor, F (z), will be limited to the Technical Specif.ications q
' values of:
F (z)
.237 [X(z)] for P.> 0.5 and q
F (z) n 4.474 [K(z)] for P < 0.5 f

I The appropriate W(z) functions, when applied to a power distribution measured under equilibrium conditions, demonstrates that the initial conditions assumed in the LOCA are met, along with the ECCS acceptance criteria of 10CFR50.46.
