Dear Mr. Murley:
In Reference (a), Commonwealth Ediscn communicated its position that equipment installed as a result of TMI Lessons Learned implementation (NUREG 0737), should be removed from the Equipment Qualificatiori (EQ) program, pending completion of Detailed Control Room Design Review (DCRDR), Reg. Guide 1.97, Rev. 2 implementation. We also indfcated in Reference (a) that inclusion of such equipment as acoustic monitors and containment hydrogen analyzers will l
be re-evaluated in accordance with their respective schedules. This statement was reiterated in Reference (b).

g Mr. T.E. Murley May 29, 1987 In our August 1, 1985 submittal of completion to Reg. Guide 1.97 (Reference (d)), we stated that we comply with the EQ requirements of Reg.
Guide 1.97 commitments. Additionally, at this time, there is still one non-EQ component on each of the above systems. The remainder of the installation is qualified.
Pages 5 and 6 of your safety evaluation (Reference (c)) agree with our position as stated in the March 30, 1984 letter (Reference (b)). Thus, we believe that the acoustic monitoring and containment hydrogen analyzers (containment atmosphere) commitments for completion of EQ are similar to the commitments of the other Reg. Guide 1.97 mods. The schedule called for comple-tion of the Quad Cities Unit 1 Reg. Guide 1.97 mods in December 1987 and Quad Cities Unit 2 in Spring 1988. The most recent Reg. Guide 1.97 schedule update had been provided to you in References (e) and (f).
Please direct any questions you may have regarding this matter to this office.
Very truly yours, t
