(c): T. M. Novak letter to Cordell Reed dated September 8, 1982.

Dear Mr. Novak:

Re ference (a) requires that Commonwealth Edison Company submit the results of an independent review of the HVAC system prior to exceeding 50% power operation at LaSalle County Station. Re ference (b) explained that we currently expect that C. F. Braun will complete their review by approximately October 8, 1982.

The purpose of this letter is to transmit to you the C.F. Braun Independent HVAC Review - Interim Report, dated September 15, 1982. As explained in Reference (b), it is our understanding that much of the information in this report will be directly incorporated into the final report to be prepared by C.F. Braun. Therefore, a detailed review o f this report should reduce the time required for the final report review by your staff.

The NRC has identified six items in Reference (c) which require clarification of the Braun work plan. In order to address these comments, outlined below are our comments and a brief description o f the sections af the Braun Interim Report which address and further clarify these items:

e8 Item 1 Commonwealth Edison and C.F. Braun concur with this

  • $ item. See the Work Plan Statement referenced on Page gy 5, para. 2. g($ f 00 Item 2 Commonwealth Edison and C.F. Braun concur with this S o item. See the Work Plan Statement referenced on Page un 6, para . 4.

ONO "U

All observations that Braun's site review committee submits to CECO for disposition will be acknowledged in the C.F. Braun final report. C.F. Braun concurs with this item.

T. M. Novak September 20, 1982 Item 4 All observstions that the C.F. Braun internal review committee determines are safety concerns are to be discussed in the C.F. Braun final report. C.F. Braun concurs with this item.

Item 5 C.F. Braun will submit their final report to Commonwealth Edison and the NRC simultaneously as addressed by C.F. Braun in their August 25, 1982 Technical Proposal - Revision 1, Page 1-3. C.F.

Braun's statement in the last paragraph on page 1-2 o f this technical proposal should have been revised to agree with the statement of simultaneous submittal.

This was a typographical oversight by C.F. Braun.

Item 6 (ref. Appendix B, Procedure 3, Ob se rva tions/ Findings Report page B3-1, last three paragraphs.

The oversight by C.F. Braun in their technical proposal is clarified in the above Quality Control Procedure confirming that Commonwealth Edison will be notified immediately for any item required for disposition by the second level review committee.

In addition to the above clarifications, Commonwealth Edison is issuing a Change Order to C.F. Braun & Co. specifically addressing these six items.

You should note that a copy of the Interim Report was also directly transmitted to Mr. James G. Keppler, Regional Administrator, Region III by C. F. Braun.

Enclosed for your use are one (1) signed original and thirty-nine (39) copies of this letter and the enclosure.

Please contact this office if there are any questions in this j matter.

Very truly yours,
