PEAKING FACTOR LIMIT REPORT FOR CATAWBA-UNIT.2 CYCLE 3 RAOC OPERATION This Peaking Factor Limit Report is provided in accordance with Paragraph 6.9.1.9 of the Catawba Unit 2 Technical Specifications.
I i
The Catawba Unit 2 Cycle 3 elevation dependent'W(z) values for RAOC operation at beginning, middle (6000 MWD /MTU), middle (10,000 MWD /MTU), and.near end-of-life are shown in Figures:1 through 4,
. This information-is sufficient to determine W(z) versus
.respectively.
core height for Cycle 3 burnups in the range of,0 MWD /MTU to 13800 i
1 MWD /MTU through the use of three point interpolation.
W(z) values for RAOC operation were calculated using the method described in'Part B of Reference 1.
The appropriate W(z) function is used to confirm that the heat flux hot channel factor, Fq(z), will be limited to the Technical Specification j
values of:
[K(z)] f r P > 0.50 and FM z) $
Fq(z) $ 4.64 [K(z)] for P $ 0.50 The apptspriate"e'evation dependent W(z) values, when applied tu a power dutribution measured under equilibrium. conditions, demonstrates that the initial canditions assume 1 in the LOCA are met, along with the ECCS acceptance criteria of 10CFR50.46.
