  • RADIAL PEAKING FACTOR LIMIT REPORT This radial Peaking Factor Limit Report is provided in accordance with Paragraph 6.9.1.9 of the Salem Unit 1 Nuclear Plant Technical Specifications.

The Fxy limits for RATED THERMAL POWER within specific core planes for Cycle 11 shall be:

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

~TP xy -

< 2.28 for all core elevations (INCORE axial points 1 through 61, inclusive).

2. For all unrodded planes:

~TP xy -

< 1.67 for all core elevations (INCORE axial points 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:

FQ( z ) < [ 2. 32] [K(z)] for P > 0.5 and, p

[K(z)] for P < 0.5 assuming the most limiting 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 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 LOCA analysis are met, along with the ECCS acceptance criteria of 10CFRS0.46.

See Figure 1 for a plot of [FQT . PRel] versus Axial Core Height.
