February 23, 1998 Mr. Oliver D. Kingsley President, Nuclear Generation Group Commonwealth Edison Company ATTN: Regulatory Services Executive Towers West lll 1400 Opus Place, Suite 500 Downers Grove,IL 60515
Dear Mr. Kings'ey:
This refers to the meeting conducted at the Region lli Office of the Nuclear Regulatory I
Commission (NRC) in Lisle, lilinois, on February 6,1998. This meeting was to discuss the status of your actions to improve fire protection at Quad Cities Station with regards to the 4
requirements of 10 CFR 50, Appendix R. During the meeting, a number of questions were highlighted regarding the use of the Interim Alternative Safe Shutdown Method (IASM),
Individual Plant Examination for External Event (IPEEE) sensitivities, and whether the revised safe shutdown analysis will fully comply with the requirements of 10 CFR 50, Appendix R.
In accordance with Section 2,790 of the NRC's " Rules of Practice," Part 2, Title 10, Code of Federal Regulations, a copy of this letter and the enclosures will be placed in the NRC's Public Document Room.
We appreciate your cooperation in this matter, if you have any questions regarding this meeting, please contact me at 620/829 9700.
Sincerely,
/
