• RADIAL PEAKING FACTOR LIMIT REPORT This radial Peaking Factor Limit Report is provided in accordance with Paragraph 6.9.l.10 of the Salem Unit 2 Nuclear Plant Technical Specifications.

The Fxy limits for RATED THERMAL POWER within specific core planes for Cycle 7 shall be:

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

_RTP r--xy -< 2.26 for all core elevations ',INCORE axial points 1 through 61, inclusive).

2. For all unrodded planes:

1-TP < 1.68 for all core elevations (INCORE axial points xy -

1 through 61, inclusive).

These F (z) limits were used to confirm that the heat flux hot xy channel factor FQ(z) will be limited to the Technical Specification values of:

32 F (z) < ( 2 * ] (K( z )]. f or P > 0 . 5 and ,

Q p FQ(z) ~ (4.64] (K(z)J for P < 0.5 assuming the most limiting axial power distributions expected to result from the insertion and removal of control Banlcs C and D during operation, including the accompanying variations in the axial xenon and power distributions as described in the "Power Distribution Control and Load Following Procedures", WCAP-8385, September, 1974.

Therefore, these F limits provide assurance that the initial xy conditions assumed in the I..OCA analysis are met, along w~th the ECCS acceptance criteria of lOCFR.50.46.
