Dear Mr. Kingsley:
This refers to the meeting conducted at the Region ill office of the Nuclear Regulatory Commission (NRC) in Lisle, Illinois, on December 10,1997. This meeting was to discuss the status of your actions to improve fire protection at Quad Cities Station with regards to the requirements of 10 CFR Part 50, Appendix R.
During this meeting, you were unable to demonstrate that the current safe shutdown analysis and pmcedures were adequately reviewed, validated, and approved to assure that a design basis fire in any plant area will not prevent the performance of necessary safe shutdown functions.
Subsequently, you shut down Unit 1, the remaining operating unit, to further evaluate corrective actions to be taken.
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 630/829-9700.
Sincerely, John A. Grobe, Director Division of Reactor Safety Docket Nos. 50-254; 50 265 License Nos. DPR 29; DPR 30

Station Responded Conservatively to Appendix R Safe Shutdown Analysis Concerns Original Safe Shutdown Analysis Had Weaknesses That Went Uncorrected
~
Program was Subject to Enforcement in 1988 and 1993 September 26,1997 Identified un Apparent Major Problem (lack ofload shedding)
Prompt Conservative Action was Taken
- All Safe Shutdown Paths Were Declared Inoperable
- Voluntary Unit 2 Shutdown on September 27,1997 7
00 Background - Unit 1 ISSM Station Engineers' Thor (ough Review)of Sa Cont.
Analysis Led to Simplified Approach (ISSM) l Rigorous Detailed Review of Original Analysis Revealed More l
Issues
- Mal Operations - EDG
- Spurious Operations - 125VDC October 24,1997, Decided To Revise SSD Approach
- Simplified Paths
- Eliminated Many Previous Issues
