Response for Clarification on List of Commitments

1) January 31, 2003 Letter from Michael P. Gallagher (Exelon), to NRC Document Control Desk Regarding Response to Request for Additional Information Related to License Renewal

2) Conference call between Exelon and NRC staff on February 5, 2003 regarding list of commitments

Dear Sir/Madam:

Reference letter 1 Attachment 1 transmitted a list of commitments that included future actions as identified in the Updated Final Safety Analysis Report (UFSAR) Supplement Appendix A, of the Reference letter 1. Subsequently in the Reference 2 telephone call, the NRC provided comments on the commitment list and requested two additional commitments be incorporated that were included in the UFSAR Supplement. to this letter revises the list of commitments and includes these two additional commitments as line items 26 and 27. These commitments relate to RPV studs and to environmental fatigue.

If you have any questions or require additional information, please do not hesitate to call.

I declare under penalty of perjury that the foregoing is true and correct.

Respectfully, Executed on 0__06__0_
