RADIAL PEAKING FACTOR LIMIT REPORT This radial Peaking Factor Limit Report is provided in accordance with Paragraph 6.9.1.10 of the Salem Unit 2 Nuclear Plant Technical Specifications.

The F:icy limits for RATED THERMAL POYER within specific core plaries for Cycle 8 shall be:

1. For all core planes containing Bank "D" control Rods:

F:qltlP s 2.23 for all core elevations (INCORE axial points 1 through 61, inclusive).

2. For all unrodded planes:

ltlP F:q s 1.69 for all core elevations (INCORE axial points 1 through 61, inclusive.

These Fzy(z) limits were used to confirm that the heat flux hot changed factor F0 (z) will be limited to the Technical Specification values of:

F0 (z) s [ 2.p32]' [K(z) for P > 0.5, and

[K(z)] for P s 0.5 assuming the most lilliting 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 di*tributions as described in the "Power Distribution Control and Load Following Procedures", WCAP-8385, September, 1974. Therefore, these Fzy limits provide assurance that the initial conditions assumed in the LOCA analysis are met, along with the ECCS acceptance criteria of 10CFR50.46.

See Figure 1 for a plot of (FJ. Pb/] versus Axial Core Height.
