Subject:

Supplement to Request for Amendment to Technical Specifications Section 3.4.11, `RCS Pressure and Temperature (PIT) Limits"

Reference:

Letter from K. R. gJury (Exelon Generation Company, LLC) to U. S. NRC, "Request for Amendment to Technical Specifications Section 3.4.11, 'RCS Pressure and Temperature (P/T) Limits,"' dated January 31, 2003 In the referenced letter, Exelon Generation Company, LLC (EGC) requested a license amendment to revise Technical Specifications (TS) Section 3.4.11, "RCS Pressure and Temperature (PIT) Limits," to incorporate revised PIT curves for LaSalle County Station (LCS),

Units 1 and 2. Subsequently, the vendor that performed the calculations for the PIT limits, General Electric (GE) Company, identified required changes to the proposed P/T limits and the supporting information.

Attachments 1 and 2 to this letter provide the TS markup pages incorporating the revised PIT limits for LCS. These pages replace in their entirety the TS pages provided in the referenced letter. Attachment 3 provides revised GE proprietary reports supporting the revised PIT limits.

These GE reports replace in their entirety the reports provided in the referenced letter.

Changes to the reports have been indicated by revision bars, and a summary of changes is provided on Page iii of each of the reports. Attachment 4 provides non-proprietary versions of the GE reports.

Requests for withholding this information from disclosure, in accordance with 10 CFR 2.390, "Public inspections, exemptions, requests for withholding," paragraph (a)(4), are provided in each report.

EGC has determined the enclosed information does not affect the finding of no significant hazards consideration provided in the referenced letter.

Should you have any questions concerning this submittal, please contact Mr. A. R. Haeger at (630) 657-2807.
