Mr. Steven A. Varga, Chief Operating Reactors Branch No. 1 Division of Licensing Gentlemen:
CYCLE 3 RADIAL PEAKING FACTOR LIMIT REPORT FACILITY OPERATING LICENSE DPR-75 UNIT NO. 2 SALEM GENERATING STATION DOCKET NO. 50-311 Attached is the Salem Unit 2 Cycle 3 Peaking Factor Limit Report.
It is provided in accordance with paragraph 6.9.1.10 of the Salem Unit 2 Technical Specifications.
The Radial Peaking Factor Limit Report has been prepared by Westinghouse in accordance with the Westinghouse Methodology, "Power Distribution Control and Load Following Procedure, WCAP-8385, September 1974".
PSE&G has reviewed this report and concurs with the proposed limits.

NFU 85-022 1/16/85 Radial Peaking Factor Limit Report This Radial Peaking Factor Limit Report ~s provided in accordance with Paragraph 6.9.1.10 of the Salem Unit 2 Nuclear Plant Technical Specifications.
The Fxy 1imits for RATED THERMAL POWER within specific c.ore planes for Cycle 3 sha11 be:
- 1.
For a11 core planes containing bank "D" control rods;
- F~~P !. 1.89 for core elevations up to 6.0 ft.,
F~~P !. 1.72 for core elevations fonn 6.0 to 12.0 ft., and
- 2.
For all unrodded planes; FRTP
< 1.61 for core elevations up to 6.0 ft., and xy *-
FRTP !. 1.66 for core elevations from 6.0to12.0 ft.
xy These Fxy(z) limits were* used to confirm that the heat flux hot channel factor FQ(z) will be limited to the Technical Specification values of:
F0(z) ~ [
2 p 3~]
[K(z)]
F0(z) ~ [4.64]
[K(z)]
for P
> 0.5 and, 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 po~r distri-butions as described in the "Power Distribution Control and Load Following Procedures 11, WCAP-8385, September, 1974.
Therefore, these Fxy limits provide assurance that the initial conditions assumed in the LOCA analysis are met, along with the ECCS acceptance criteria of 10CFRS0.46.
See Figure 1 for a plot of [F0T.pRel] vs. Axial Core Height.
