LaSalle County Station Unit 2 Environmental Qualification of Electrical Equipment NRC Docket-50-374-References (a): September 4, 1981 letter from L. O. DelGeorge to A. Schwencer. (b): Section 3.11, SER (March 1981), SSER #1 (June 1981), SSER #2 (Feb. 1982). 7 (c): Janauary 8, 1985 letter from J. G. Marshall to H. R. Denton.

Dear Mr. Denton:

In accordance with a. request made by Dr. A. Bournia during a'telecon of January 22, 1985, the following information is provided. It is intended to supplement the Reference (c) submittal regarding an extension.on the schedular requirements of 10CFR 50.49 (g). Provided as Attachment A is a table which identifies by. equipment. number each application for which an extension is being sought. Also identified is the manufacturer and model number of the . pertinent item. -This table corresponds directly to the report r provided in Reference (c) which broadly reviews the actions required to attain a qualified status and proposes a schedule for implementa- -tion. Further,'in the column headed " Reference", the page number is

identified.from the LaSalle County Assessment to Justify Interim Operation, VOL II, QUAD-1-81-852 (Rev. 3, June 1982) compiled by Quadrex, Corporation, where the item was individually reviewed by function, failure mode and effects, and whether operator action was required for the needed safety function.

For your convenience, copies of the pertinent pages are provided in Attachment B. A048 . 85021 tr)?ti cgyg-DR ADOCM 05000374 PDR j

}f 9 s H. R. Denton January 30, 1985 Recall that the main volume of the report was transmitted ~ to the Commission per Reference (a) and followed-up by explanatory FMEA's via letter of October 22, 1981; the commission's acceptance was provided in Reference (b) following the field audit of October 1981. The up-dated revision of the JIO report which included the Component Application Statements was transmitted to the Commission as a part of the 90-day response to the SER in June 1982. Although this study was undertaken prior to issuance of the rule, it is our judgement that all provisions of 10CFR 50.49 (i) are adequately addressed. Should you need any further information, please contact this office. Very truly yours, E j90 w/wkb[ J. G. Marshall Nuclear Licensing Administrator 1m cc: A.
