The applicability of topical report NEDO-32205-A, Revision I has been confirmed for Quad Cities Units 1 and 2.

Quad Cities Units I and 2 Near-core material surveillance data for Quad Cities Units 1 and 2 were evaluated as specified in Appendix B of the NEDO Report. The Appendix H capsule data shown in Table 13 of Reference (e) (also provided as Enclosure 1 in Reference (d)) were excluded from this evaluation because the fluence values are below the range of Regulatory Guide 1.99 Rev. 2, ,

Figure 2. Ten of the surveillance data shown in Table 14 of Reference (e)(also provided as Enclosure 2 in Reference (d)) show a decrease in USE less than predicted in Regulatory Guide 1.99 Rev. 2, and the equivalent margin of the NEDO Report is bounding for the plant.

For the two Quad Cities Unit 2 submerged are weld surveillance data points which show a  ;

decrease in USE greater than predicted in Regulatory Guide ~ 1.99 Rev. 2, the plant applicability verification of Appendix B of the NEDO Report was performed, and the results show that the equivalent margin analysis is still bounding for the plant. This information is provided in the Enclosure to this letter.

To the best of my knowledge and belief, the information contained herein is true and correct. In some respect, this information is not based on my personal knowledge, but upon  ;

information furnished by other Commonwealth Edison and contractor employees. Such information has been reviewed in accordance with company practice, and I believe it to be reliable.

We trust that the information is satisfactory; however, should you have any questions, or desire.mtv. additional inrnym onn on ,

this issue, please do not hesitate to contact this office.
