Reference (a):
J. G. Keppler letter to Cordell Reed dated August 18, 1981.
(b):
T. J. Rausch letter to J. G. Keppler dated May 8, 1981.
Dear Mr. Keppler:
Reference (a) requested the Commonwealth Edison Company to review the subject bulletin supplement for applicability to our operating stations and report the results within thirty (30) days.
This letter is provided to fulfill this thirty (30) day requirement for our Dresden, Quad Cities and Zion Statioris.
In addition, this latter also provides the requested sixty (60) day report for our LaSalle County Station.
Commonwealth Edison has reviewed Supplement 1 to I.E.
7M Bulletin 81-02.
We have determined that none of the valves in question have been installed, or are maintained as spares for 3
installation, in safety-related systems where they are required to
/
close against a differential pressure at our Dresden, Quau Cities,
//9 Zion, or LaSalle County Stations with the following exception.
As stated in Reference (b), one spare valve of the Westinghouse EMD 4-inch type is maintained as a spare at Zion.
This valve was placed in the Q.A. hold area and will not be used unless it is qualified for its intended service.

Based upon the above and the directive given in the subject bullatin supplement, no further action or response is required for our Dresden, Quad Cities, Zion or LaSalle County Stations regarding this issue.
Our current schedule for submittal of the Byron and Braidwood sixty (60) uay report is on or before October 17, 1981.
To the best of my knowledge and belief, the statements contained herein are true and correct.

Such information has been reviewed in accordance with Company practice and I believe it to be reliable.
Please address any questions you may have concerning this matter to this office.
