NUCLEAR RESULATORY COMMISSION WASHINGTON, D.C. 3000H001 4

\ *** */ December 14, 1998 Mr. Brian A. McIntyre, Manager Advanced Plant Safety and Licensing Energy Systems Business Unit Westinghouse Electric Company P.O. Box 355 Pittsburgh, PA 15230

SUBJECT:

RETURN OF PROPRIETARY MATERIAL TO WESTINGrlOUSE DOCKETED UNDER THE AP600 DESIGN REVIEW ,

Dear Mr. McIntyre:

By Westinghouse letter NTD-NRC-95-4556, dated September 18,1955, you provided a status i

report on proprietary material submitted to the U. S. Nuclear Regulatory Commission (NRC) to support the AP600 design review effort. This report was in response to an NRC letter dated August 11,1995, to you which requested Westinghouse to determine if any of the AP600 submittals were: (1) no longer considered to be proprietary under 10 CFR 2.790, or; (2) no longer current and applicable to the AP600 design.

As a result of this review, you identified a number of proprietary submittals to be retumed to Westinghouse which you no longer considered necessary to support the AP600 design

, certification effort. The primary reason you cited for recalling this proprietary material was that most of the documents and submittals have been superseded or revised by a later version.

Subsequent to the September 18,1995, letter Westinghouse has provided proprietary material that was also superseded or revised by a later version. The staff has determined that in specific cases this material was not used by the staff to make a safety determination and should be retumed to Westinghouse. Discussions with members of your licensing staff revealed that Westinghouse also believes that it is important to retract these documents to i minimize the amount of proprietary material on the AP600 docket and reduce the chance that material outside of Westinghouse control could be inadvertently compromised. You have requested that this material be reiamed even if the NRO has determined that the materialis proprietary.

The NRC technical review staff has performed an assessment of the documents to be retracted to ensure that they are not relied on to support its safety determination relative to the AP600 review and are wholly superseded by later Westinghouse submittals which can support the staff's' safety determination independent of the retracted material. During discussions and a meeting with your staff, you were told that documents submitted in support of the AP600 q application are subject to the retention requirements of 10 CFR Part 50, Appendix A, ,

Criterion 1, and will be retained for the lifetime of the application. By Westinghouse letter ^'(o/

NSD-NRC-96-4689, dated April 12,1996, you provided written confirmation that all AP600 related proprietary documents, which have been identified for retraction, will be permanently retained by Westinghouse pursuant to 10 CFR Part 50. Based on your assurances that the retracted documents will be retained at Westinghouse, we are satisfied that an adequate mechanism exists for NRC retrieval and inspect!on of these documents if required.

g, l Mr. Brian A. McIntyre December 14, 1998 As a consequence of this effort, and in accordance with your request, the staff has removed the proprietary documents listed in the Enclosure from the AP600 docket file and is returning them to Westinghouse for your disposition or retention as necessary. The original document contained in the docket file is being retumed. NRC staff, contractors, or other parties who l received internal NRC distribution have been notified to destroy their copies. The staff notes l that the forwarding letter and the letter requesting that the material be treated as proprietary I information associated with the retracted material, along with any non-proprietary version of the submittal which have been placed in the Public Document Room, will remain on the docket.

The staff will continue to evaluate other proprietary documents identified in Westinghouse letter l NTD-NRC-95-4556 and retum them as appropriate.
